CVSS v3.1 |
| Time-of-check time-of-use (toctou) race condition in Microsoft Defender for Linux allows an authorized attacker to deny service locally. |
| Inadequate encryption strength in .NET, .NET Framework, Visual Studio allows an authorized attacker to disclose information over a network. |
| Improper link resolution before file access ('link following') in .NET allows an authorized attacker to elevate privileges locally. |
| Type Confusion in V8 in Google Chrome prior to 142.0.7444.175 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High) |
| In the Linux kernel, the following vulnerability has been resolved:
Revert "NFSD: Remove the cap on number of operations per NFSv4 COMPOUND"
I've found that pynfs COMP6 now leaves the connection or lease in a
strange state, which causes CLOSE9 to hang indefinitely. I've dug
into it a little, but I haven't been able to root-cause it yet.
However, I bisected to commit 48aab1606fa8 ("NFSD: Remove the cap on
number of operations per NFSv4 COMPOUND").
Tianshuo Han also reports a potential vulnerability when decoding
an NFSv4 COMPOUND. An attacker can place an arbitrarily large op
count in the COMPOUND header, which results in:
[ 51.410584] nfsd: vmalloc error: size 1209533382144, exceeds total
pages, mode:0xdc0(GFP_KERNEL|__GFP_ZERO),
nodemask=(null),cpuset=/,mems_allowed=0
when NFSD attempts to allocate the COMPOUND op array.
Let's restore the operation-per-COMPOUND limit, but increased to 200
for now. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix memory leak of qgroup_list in btrfs_add_qgroup_relation
When btrfs_add_qgroup_relation() is called with invalid qgroup levels
(src >= dst), the function returns -EINVAL directly without freeing the
preallocated qgroup_list structure passed by the caller. This causes a
memory leak because the caller unconditionally sets the pointer to NULL
after the call, preventing any cleanup.
The issue occurs because the level validation check happens before the
mutex is acquired and before any error handling path that would free
the prealloc pointer. On this early return, the cleanup code at the
'out' label (which includes kfree(prealloc)) is never reached.
In btrfs_ioctl_qgroup_assign(), the code pattern is:
prealloc = kzalloc(sizeof(*prealloc), GFP_KERNEL);
ret = btrfs_add_qgroup_relation(trans, sa->src, sa->dst, prealloc);
prealloc = NULL; // Always set to NULL regardless of return value
...
kfree(prealloc); // This becomes kfree(NULL), does nothing
When the level check fails, 'prealloc' is never freed by either the
callee or the caller, resulting in a 64-byte memory leak per failed
operation. This can be triggered repeatedly by an unprivileged user
with access to a writable btrfs mount, potentially exhausting kernel
memory.
Fix this by freeing prealloc before the early return, ensuring prealloc
is always freed on all error paths. |
| VestaCP commit a3f0fa1 (2018-05-31) up to commit ee03eff (2018-06-13) contain embedded malicious code that resulted in a supply-chain compromise. New installations created from the compromised installer since at least May 2018 were subject to installation of Linux/ChachaDDoS, a multi-stage DDoS bot that uses Lua for second- and third-stage components. The compromise leaked administrative credentials (base64-encoded admin password and server domain) to an external URL during installation and/or resulted in the installer dropping and executing a DDoS malware payload under local system privileges. Compromised servers were subsequently observed participating in large-scale DDoS activity. Vesta acknowledged exploitation in the wild in October 2018. |
| In the Linux kernel, the following vulnerability has been resolved:
mtd: parsers: ofpart: Fix refcount leak in bcm4908_partitions_fw_offset
of_find_node_by_path() returns a node pointer with refcount incremented,
we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak. |
| This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. |
| A flaw was found in the Linux kernel's memory deduplication mechanism. The max page sharing of Kernel Samepage Merging (KSM), added in Linux kernel version 4.4.0-96.119, can create a side channel. When the attacker and the victim share the same host and the default setting of KSM is "max page sharing=256", it is possible for the attacker to time the unmap to merge with the victim's page. The unmapping time depends on whether it merges with the victim's page and additional physical pages are created beyond the KSM's "max page share". Through these operations, the attacker can leak the victim's page. |
| A null pointer dereference vulnerability was found in ath10k_wmi_tlv_op_pull_mgmt_tx_compl_ev() in drivers/net/wireless/ath/ath10k/wmi-tlv.c in the Linux kernel. This issue could be exploited to trigger a denial of service. |
| A null pointer dereference vulnerability was found in dpll_pin_parent_pin_set() in drivers/dpll/dpll_netlink.c in the Digital Phase Locked Loop (DPLL) subsystem in the Linux kernel. This issue could be exploited to trigger a denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: check stream id dml21 wrapper to get plane_id
[Why & How]
Fix a false positive warning which occurs due to lack of correct checks
when querying plane_id in DML21. This fixes the warning when performing a
mode1 reset (cat /sys/kernel/debug/dri/1/amdgpu_gpu_recover):

soc: amlogic: Fix refcount leak in meson-secure-pwrc.c
In meson_secure_pwrc_probe(), there is a refcount leak in one fail
path. |

virtio-gpu: fix a missing check to avoid NULL dereference
'cache_ent' could be set NULL inside virtio_gpu_cmd_get_capset()
and it will lead to a NULL dereference by a lately use of it
(i.e., ptr = cache_ent->caps_cache). Fix it with a NULL check.

ath9k: fix use-after-free in ath9k_hif_usb_rx_cb
Syzbot reported use-after-free Read in ath9k_hif_usb_rx_cb() [0]. The
problem was in incorrect htc_handle->drv_priv initialization.
Probable call trace which can trigger use-after-free:
ath9k_htc_probe_device()
/* htc_handle->drv_priv = priv; */
ath9k_htc_wait_for_target() <--- Failed
ieee80211_free_hw() <--- priv pointer is freed
<IRQ>
...
ath9k_hif_usb_rx_cb()
ath9k_hif_usb_rx_stream()
RX_STAT_INC() <--- htc_handle->drv_priv access
In order to not add fancy protection for drv_priv we can move
htc_handle->drv_priv initialization at the end of the
ath9k_htc_probe_device() and add helper macro to make
all *_STAT_* macros NULL safe, since syzbot has reported related NULL
deref in that macros [1] |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: use list_first_entry_or_null for opinfo_get_list()
The list_first_entry() macro never returns NULL. If the list is
empty then it returns an invalid pointer. Use list_first_entry_or_null()
to check if the list is empty. |
| In the Linux kernel, the following vulnerability has been resolved:
arm64: dts: qcom: x1e80100: Add GPU cooling
Unlike the CPU, the GPU does not throttle its speed automatically when it
reaches high temperatures. With certain high GPU loads it is possible to
reach the critical hardware shutdown temperature of 120°C, endangering the
hardware and making it impossible to run certain applications.
Set up GPU cooling similar to the ACPI tables, by throttling the GPU speed
when reaching 95°C and polling every 200ms. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: don't warn when if there is a FW error
iwl_trans_reclaim is warning if it is called when the FW is not alive.
But if it is called when there is a pending restart, i.e. after a FW
error, there is no need to warn, instead - return silently. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Don't treat wb connector as physical in create_validate_stream_for_sink
Don't try to operate on a drm_wb_connector as an amdgpu_dm_connector.
While dereferencing aconnector->base will "work" it's wrong and
might lead to unknown bad things. Just... don't. |
