CVE-2026-14671 1 Postgresql 1 Postgresql 2026-08-29 8.8 High
Type confusion in PostgreSQL module "refint" allows an object creator to execute arbitrary code as the operating system user running the database. The fix for this emerged as a non-security bug report, and the fix appear in the git repository with subject "refint: Remove plan cache.", without a CVE number. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
CVE-2026-6471 1 Postgresql 1 Postgresql 2026-08-29 7.2 High
Missing authorization in PostgreSQL logical decoding allows a non-superuser holding REPLICATION privilege to dlopen any file visible to the operating system account running the server, via the choice of logical decoding plugin. This in turn runs arbitrary code as that account. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
CVE-2026-6470 1 Postgresql 1 Postgresql 2026-08-29 4.3 Medium
Missing authorization in PostgreSQL DDL commands allows an object creator to achieve denial of service against ALTER and DROP of the type, via creating a dependency on the type. Many DDL operations did check the privilege, but assigning a range subtype and referencing the type from an SQL expression did not. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
CVE-2026-6464 1 Postgresql 1 Postgresql 2026-08-29 8.1 High
Untrusted data inclusion in PostgreSQL psql COPY may allow a server administrator to elicit execution of data lines as psql commands, via error injection. If the "COPY FROM STDIN" or "\copy FROM STDIN" command fails before the server indicates that it awaits input rows, psql processes the in-line data rows as psql commands. "COPY FROM" with a filename is unaffected. The server administrator has no inherent control over the data rows, so a complete attack requires the attacker to separately acquire control of both the server and the data rows. Alternatively, an attacker controlling data rows alone might complete an attack through a coincidental error that they don't control. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
CVE-2026-18408 1 Postgresql 1 Postgresql 2026-08-29 8.8 High
Untrusted data inclusion in pg_dump in PostgreSQL allows a malicious superuser of the origin server to inject arbitrary code for restore-time execution as the client operating system account running psql to restore the dump, via psql \restrict meta-command input expansion. The fix for CVE-2025-8714 introduced \restrict and \unrestrict to block this attack, but \unrestrict itself was sufficient for an attack. pg_dumpall is also affected. pg_restore is affected when used to generate a plain-format dump. Non-core use of \restrict would be affected, but we've not identified non-core use. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
CVE-2026-16239 1 Postgresql 1 Postgresql 2026-08-29 8.8 High
Type confusion in PostgreSQL "portal"/cursor lifecycle allows a user to execute arbitrary code as the operating system user running the database, via re-creation of a cursor or other portal with different types. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
CVE-2026-16238 1 Postgresql 1 Postgresql 2026-08-29 8.8 High
Type confusion in PostgreSQL pg_restore_attribute_stats() allows an object creator to execute arbitrary code as the operating system user running the database, via conflation of range and multirange values. Within major version 18, minor versions before PostgreSQL 18.6 are affected. Versions before PostgreSQL 18 are unaffected.
CVE-2026-15741 1 Postgresql 1 Postgresql 2026-08-29 8.8 High
SQL injection in PostgreSQL EXTRACT() deparse allows an object owner to execute arbitrary SQL as a superuser via a hostile object definition. Attacks affect expression deparse consumers broadly, including pg_dump, psql commands like \sf, and any similar usage in non-core tools. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
CVE-2026-14680 1 Postgresql 1 Postgresql 2026-08-29 8.8 High
Type confusion with PostgreSQL "internal" data type arguments allows any user to execute arbitrary code as the operating system user running the database, via calls to functions with that argument type. Type "internal" represents a class of mutually-incompatible data structures not intended for access from SQL. The system intended to prevent such function calls, but this prevention had gaps. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
CVE-2026-14668 1 Postgresql 1 Postgresql 2026-08-29 8.1 High
Type confusion regarding input of PostgreSQL ctid data type selectivity estimator allows an object creator to view a calculation derived from the value of an arbitrary 4-byte span of memory, via a chosen non-ctid input. While the calculation loses precision, substantial memory value recovery appears possible. Versions before PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 are affected.
CVE-2026-69555 1 Microsoft 1 Azure Arc 2026-08-29 10 Critical
Incorrect authorization in Azure Arc allows an unauthorized attacker to elevate privileges over a network.
CVE-2026-80707 1 Linux 1 Linux Kernel 2026-08-29 7.5 High
In the Linux kernel, the following vulnerability has been resolved: can: j1939: transport: j1939_session_fresh_new(): initialize receive buffer Zero the allocated buffer in j1939_session_fresh_new() to ensure it contains no residual data. While there is a potential performance impact if users allocate maximum sized ETP buffers, most real-world use cases are not noticeably affected since the maximum known buffer size is typically around 65K.

CVE-2026-80712 1 Linux 1 Linux Kernel 2026-08-29 8.4 High
In the Linux kernel, the following vulnerability has been resolved: spi: spi-qpic-snand: write the feature value before executing SET_FEATURE qcom_spi_send_cmdaddr() programs NAND_FLASH_CMD/NAND_EXEC_CMD and submits the descriptors, which makes the controller execute the command immediately. For SPINAND_SET_FEATURE the value to be written is only placed into NAND_FLASH_FEATURES afterwards, by qcom_spi_io_op(), in a second submission - so the chip is programmed with whatever that register happened to hold from a previous operation, and the intended value is only applied by the *next* SET_FEATURE. Measured on a TP-Link Archer AX55 v1 (IPQ5018, ESMT F50L1G41LB): writing 0x40 to the configuration register (0xb0) leaves the chip at 0x00, and the subsequent write of 0x00 leaves it at 0x40 - every write lands one operation late. This stayed unnoticed until v6.18 added SPI-NAND OTP support together with OTP entries for ESMT chips. spinand_otp_rw() enables OTP mode, reads, and disables it again, and mtd_otp_nvmem_add() does this during MTD registration. With the off-by-one, the "disable" write actually applies the previously requested value, so CFG_OTP_ENABLE ends up set: the chip stays in OTP mode, every subsequent array read returns the OTP area instead of the array (UBI reports an empty device) and all writes fail with -EIO because the OTP area is write protected. On this board that makes the whole flash unusable and the device unbootable. Write the feature value into NAND_FLASH_FEATURES as part of the same transaction, before NAND_EXEC_CMD. While at it, copy only the bytes the operation actually carries - the previous code dereferenced a 4-byte pointer on a one-byte buffer (spinand->scratchbuf). With this patch the flash contents read back bit-identical to a known-good dump of the same board taken under the vendor firmware (md5-verified across partitions), and writes work.
CVE-2026-80680 1 Linux 1 Linux Kernel 2026-08-29 7.8 High
In the Linux kernel, the following vulnerability has been resolved: i2c: amd-mp2: Unregister callback on adapter add failure amd_mp2_register_cb() stores the platform I2C context in the MP2 PCI driver's callback table before the adapter is registered. If i2c_add_adapter() fails, probe returns and devres frees the context, but the PCI driver can still dereference the stale pointer from its IRQ and system-sleep callbacks. Unregister the callback before returning the adapter registration error.
CVE-2026-80714 1 Linux 1 Linux Kernel 2026-08-29 9.8 Critical
In the Linux kernel, the following vulnerability has been resolved: ipvs: do not propagate one-packet flag to synced conns Synced connections can be created before their destination exists. When the destination is later added, ip_vs_bind_dest() copies connection flags from the destination into cp->flags. IP_VS_CONN_F_ONE_PACKET connections are not synced. If a synced connection inherits IP_VS_CONN_F_ONE_PACKET while it is already hashed, expiry can treat it as a one-packet connection and skip unlinking the existing conn_tab node, leaving stale hash nodes pointing at a freed struct ip_vs_conn. Drop IP_VS_CONN_F_ONE_PACKET from destination flags when binding synced connections.
CVE-2026-80722 1 Linux 1 Linux Kernel 2026-08-29 8.8 High
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: validate individual TWT params before driver setup ieee80211_process_rx_twt_action() only partially validates a received S1G TWT setup frame before queueing it. An individual agreement can therefore reach ieee80211_s1g_rx_twt_setup() with twt->length too short for the full struct ieee80211_twt_params. The individual path passes twt to drv_add_twt_setup(). Both the tracepoint and the driver callback consume the complete parameters block, not merely req_type. Do not pass a short individual agreement to the driver. Broadcast agreements remain unchanged because they are rejected locally after accessing only req_type. [edit commit message to not overclaim lack of validation nor understate driver impact]
CVE-2026-80628 1 Linux 1 Linux Kernel 2026-08-29 7.8 High
In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: oss: Serialize readq reset state with q->lock snd_seq_oss_readq_clear() resets qlen, head, and tail without q->lock even though the normal reader and producer paths serialize the same ring state under that spinlock. A reset can therefore race snd_seq_oss_readq_free() or snd_seq_oss_readq_put_event() and leave stale records in the queue, drop freshly queued ones, or report the wrong readiness after wakeup. KCSAN reports a data race between snd_seq_oss_readq_clear() and snd_seq_oss_readq_free(). Take q->lock while clearing the ring and resetting input_time. Factor the enqueue logic into a caller-locked helper so snd_seq_oss_readq_put_timestamp() updates its suppression state under the same lock instead of racing the reset path. The buggy scenario involves two paths, with each column showing the order within that path: reset path: locked readq updater: 1. snd_seq_oss_reset() or 1. A reader or callback producer release reaches takes q->lock on the same queue. snd_seq_oss_readq_clear(). 2. snd_seq_oss_readq_clear() 2. The updater tests or modifies resets qlen, head, tail, qlen, head, and tail. and input_time. 3. snd_seq_oss_readq_clear() 3. The updater completes its wakes sleepers on read-modify-write sequence. q->midi_sleep. 4. Without q->lock, the reset 4. The resulting ring state drives can overlap the locked later reads and readiness. update. KCSAN reports: BUG: KCSAN: data-race in snd_seq_oss_readq_clear / snd_seq_oss_readq_free write to 0xffff8881069fe608 of 4 bytes by task 120516 on cpu 0: snd_seq_oss_readq_free+0x6c/0x80 snd_seq_oss_read+0xcb/0x250 odev_read+0x38/0x60 vfs_read+0xff/0x600 ksys_read+0xb4/0x140 __x64_sys_read+0x46/0x60 do_syscall_64+0xbb/0x2f0 entry_SYSCALL_64_after_hwframe+0x77/0x7f read to 0xffff8881069fe608 of 4 bytes by task 120517 on cpu 1: snd_seq_oss_readq_clear+0x1f/0x90 snd_seq_oss_reset+0xa7/0xf0 snd_seq_oss_ioctl+0x6f6/0x7e0 odev_ioctl+0x56/0xc0 __x64_sys_ioctl+0xd1/0x120 do_syscall_64+0xbb/0x2f0 entry_SYSCALL_64_after_hwframe+0x77/0x7f value changed: 0x00000001 -> 0x00000000
CVE-2026-80717 1 Linux 1 Linux Kernel 2026-08-29 7.5 High
In the Linux kernel, the following vulnerability has been resolved: sctp: validate Adaptation Indication parameter length The Adaptation Layer Indication parameter contains a fixed 32-bit Adaptation Code Point after its parameter header. However, sctp_verify_param() accepts a header-only parameter because the generic parameter walker only requires the header to be present. sctp_process_param() then reads adaptation_ind beyond the declared parameter. When the malformed parameter is last in an INIT, the read starts at the receive skb tail, and the value is copied into the state cookie returned in the INIT ACK. This may disclose four receive-buffer tail bytes. Require the declared parameter length to match the fixed structure size and abort the association through the existing invalid parameter length path otherwise.
CVE-2026-80661 1 Linux 1 Linux Kernel 2026-08-29 7.8 High
In the Linux kernel, the following vulnerability has been resolved: ufs: core: tracing: Do not dereference pointers in TP_printk() The trace events in drivers/ufs/core/ufs_trace.h were converted to take a pointer to the hba structure as an argument for the tracepoint and then in TP_printk() the printing of the dev_name from the ring buffer was converted to using the dev dereferenced pointer from the hba saved pointer. This is not allowed as the TP_printk() is executed at the time the trace event is read from /sys/kernel/tracing/trace file. That can happen literally, seconds, minutes, hours, weeks, days, or even months later! There is no guarantee that the hba pointer will still exist by the time it is dereferenced when the "trace" file is read. Instead, save the device name from the hba pointer at the time the tracepoint is called and place it into the ring buffer event. Then the TP_printk() can read the name directly from the ring buffer and remove the possibility that it will read a freed pointer and crash the kernel. This was detected when testing the trace event code that looks for TP_printk() parameters doing illegal derferences[1] [1] https://lore.kernel.org/all/20260630184836.74d477b6@gandalf.local.home/
CVE-2026-80600 1 Linux 1 Linux Kernel 2026-08-29 9.8 Critical
In the Linux kernel, the following vulnerability has been resolved: batman-adv: dat: acquire ARP hw source only after skb realloc The pskb_may_pull() called by batadv_get_vid() could reallocate the buffer behind the skb. Variables which were pointing to the old buffer need to be reassigned to avoid an use-after-free.
