kernel: drm/i915: Fix potential UAF in TTM object purge
A flaw was found in the Linux kernel's Intel i915 graphics driver drm/i915. This use-after-free UAF vulnerability occurs during the TTM object purge operation. An attacker could potentially exploit this to cause a system crash, leading to a denial of service...
kernel: drm/amdgpu: fix amdgpu_hmm_range_get_pages
A flaw was found in the Linux kernel, specifically within the drm/amdgpu component. This vulnerability arises from incorrect handling of a notifier sequence in the amdgpuhmmrangegetpages function, where the sequence can be read more than once. This can lead to the system processing invalid memory...
kernel: sched/psi: fix race between file release and pressure write
A flaw was found in the Linux kernel's Pressure Stall Information PSI subsystem. A race condition exists between the file release and pressure write operations, specifically concerning the priv member of struct kernfsopenfile. This can lead to a use-after-free vulnerability or a NULL dereference,...
kernel: mm/huge_memory: update file PMD counter before folio_put()
A flaw was found in the Linux kernel's memory management, specifically within the huge page mechanism. When a huge page is split, the system updates a counter after releasing a reference to the memory. This timing issue can lead to the system attempting to read from memory that has already been...
kernel: drm/amdgpu: Refactor amdgpu_gem_va_ioctl for Handling Last Fence Update and Timeline Management v4
A flaw was found in the Linux kernel's AMD GPU amdgpu driver. Incorrect management of graphics memory dmafence references within the amdgpugemvaioctl function can lead to a reference count underflow and a use-after-after-free condition. A local attacker could exploit this vulnerability to trigger...
Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update
An update for kernel is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from th...
kernel: netfilter: synproxy: refresh tcphdr after skb_ensure_writable
A flaw was found in the Linux kernel's netfilter synproxy module. When handling TCP timestamp options, a stale pointer can be used after memory reallocation. This can result in memory corruption, where data is written to a freed memory area, or lead to packets being sent with an incorrect checksu...
kernel: ip6_gre: Use cached t->net in ip6erspan_changelink()
A flaw was found in the Linux kernel's ip6gre module. An unprivileged user could exploit this vulnerability by migrating a network device, causing the ip6erspanchangelink function to incorrectly handle network namespace references. This error leads to a use-after-free condition when the original...
kernel: posix-cpu-timers: Prevent UAF caused by non-leader exec() race
A flaw was found in the Linux kernel's CPU timer functionality. A race condition, which is a timing issue between different operations, can occur when a process attempts to delete a timer while another operation is still trying to access it. This can lead to a Use-After-Free UAF vulnerability,...
kernel: blk-mq: pop cached request if it is usable
A flaw was found in the Linux kernel's blk-mq component. This use-after-free vulnerability occurs when a task attempts to submit a bio a data structure for I/O operations to blk-mq. If the task is interrupted and sleeps after checking for a cached request but before using it, the cached request c...

kernel: net: ieee802154: do not leave a dangling sk pointer in ieee802154_create()
A user-after-free vulnerability was found in the linux kernel. sockinitdata attaches the allocated sk object to the provided sock object. If ieee802154create fails later, the allocated sk object is freed, but the dangling pointer remains in the provided sock object, leading to a crash and loss of...
