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: 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...

CVE-2026-74561

A flaw was found in the Linux kernel, specifically within its nexthop component responsible for network routing. A timing issue, known as a race condition, allows the system to access memory after it has been freed. This occurs when the kernel attempts to flush its routing cache while other...

CVE-2026-74511

A flaw was found in the Linux kernel's Bluetooth management component. A race condition exists during Extended Inquiry Response EIR updates when the MGMTOPSETLOCALNAME operation is processed concurrently with modifications to the UUID list. This can lead to a use-after-free vulnerability in the...

CVE-2026-74503

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. An unprivileged local user with access to the /dev/snd/timer and /dev/snd/seq devices can exploit a race condition where a timer instance's SNDRVTIMERIFLGDEAD flag is not properly cleared after closing...

CVE-2026-74565

A flaw was found in the Linux kernel's netfilter subsystem. The global nature of the nftobject rhltable allows a local attacker to access objects that are being deallocated by other network namespaces. This can lead to a use-after-free vulnerability, potentially resulting in memory corruption or...

CVE-2026-74529

A flaw was found in the Linux kernel's Bluetooth Host Controller Interface HCI synchronization component. This vulnerability, a Use-After-Free UAF, occurs when a connection object is prematurely released while the hcisync task is still active. A local attacker could potentially exploit this to...
