| CVE-2023-1829 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-08-02 | 7.8 High |
| A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root. We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. | ||||

| A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of the CPU similar to the speculative execution behavior kind of attacks. | ||||
| CVE-2023-1582 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2024-08-02 | 4.7 Medium |
| A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel. This issue may allow a local attacker with user privilege to cause a denial of service. | ||||
| CVE-2023-1583 | 1 Linux | 1 Linux Kernel | 2024-08-02 | 5.5 Medium |
| A NULL pointer dereference was found in io_file_bitmap_get in io_uring/filetable.c in the io_uring sub-component in the Linux Kernel. When fixed files are unregistered, some context information (file_alloc_{start,end} and alloc_hint) is not cleared. A subsequent request that has auto index selection enabled via IORING_FILE_INDEX_ALLOC can cause a NULL pointer dereference. An unprivileged user can use the flaw to cause a system crash. | ||||

| CVE-2023-1476 | 2 Linux, Redhat | 6 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 3 more | 2024-08-02 | 7 High |
| A use-after-free flaw was found in the Linux kernel’s mm/mremap memory address space accounting source code. This issue occurs due to a race condition between rmap walk and mremap, allowing a local user to crash the system or potentially escalate their privileges on the system. | ||||
| CVE-2023-1390 | 2 Linux, Redhat | 5 Linux Kernel, Enterprise Linux, Rhel Aus and 2 more | 2024-08-02 | 7.5 High |
| A remote denial of service vulnerability was found in the Linux kernel’s TIPC kernel module. The while loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system to instantly spike to 100%, causing a denial of service condition. | ||||
| CVE-2023-1380 | 5 Canonical, Debian, Linux and 2 more | 14 Ubuntu Linux, Debian Linux, Linux Kernel and 11 more | 2024-08-02 | 7.1 High |
| A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading to a denial of service. | ||||
| CVE-2023-1382 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2024-08-02 | 4.7 Medium |
| A data race flaw was found in the Linux kernel, between where con is allocated and con->sock is set. This issue leads to a NULL pointer dereference when accessing con->sock->sk in net/tipc/topsrv.c in the tipc protocol in the Linux kernel. | ||||
| CVE-2023-1295 | 2 Linux, Netapp | 6 Linux Kernel, H300s, H410c and 3 more | 2024-08-02 | 7.8 High |
| A time-of-check to time-of-use issue exists in io_uring subsystem's IORING_OP_CLOSE operation in the Linux kernel's versions 5.6 - 5.11 (inclusive), which allows a local user to elevate their privileges to root. Introduced in b5dba59e0cf7e2cc4d3b3b1ac5fe81ddf21959eb, patched in 9eac1904d3364254d622bf2c771c4f85cd435fc2, backported to stable in 788d0824269bef539fe31a785b1517882eafed93. | ||||
| CVE-2023-1249 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2024-08-02 | 5.5 Medium |
| A use-after-free flaw was found in the Linux kernel’s core dump subsystem. This flaw allows a local user to crash the system. Only if patch 390031c94211 ("coredump: Use the vma snapshot in fill_files_note") not applied yet, then kernel could be affected. | ||||
| CVE-2023-1252 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2024-08-02 | 7.8 High |
| A use-after-free flaw was found in the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch 9a2544037600 ("ovl: fix use after free in struct ovl_aio_req") not applied yet, the kernel could be affected. | ||||
| CVE-2023-1281 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-08-02 | 7.8 High |
| Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. | ||||
| CVE-2023-1206 | 3 Fedoraproject, Linux, Redhat | 5 Fedora, Linux Kernel, Enterprise Linux and 2 more | 2024-08-02 | 5.7 Medium |
| A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%. | ||||
| CVE-2023-1192 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-08-02 | 6.5 Medium |
| A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service. | ||||
| CVE-2023-1193 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2024-08-02 | 6.5 Medium |
| A use-after-free flaw was found in setup_async_work in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. This issue could allow an attacker to crash the system by accessing freed work. | ||||
| CVE-2023-1195 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2024-08-02 | 5.5 Medium |
| A use-after-free flaw was found in reconn_set_ipaddr_from_hostname in fs/cifs/connect.c in the Linux kernel. The issue occurs when it forgets to set the free pointer server->hostname to NULL, leading to an invalid pointer request. | ||||
