CVE-2026-64518

CVE-2026-64518 affects the Linux kernel TCP stack. Affected component is tcp_ao_established_key(), where an out-of-bounds access can occur due to the added lockdep_sock_is_held() annotation. The issue can be triggered from tcp_v46_timewait_ack() while handling a twsk, because the code path lacks ...

CVE-2026-64516

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vce1: Fix VCE 1 firmware size and offsets The VCPU BO contains the actual FW at an offset, but it was not calculated into the VCPU BO size. Subtract this from the FW size to make sure there is no out of bounds access...

In the Linux kernel, the following vulnerability has been resolved: drm/xe/gsc: Fix double-free of managed BO in error path The error path in xegscinitposthwconfig explicitly frees a BO allocated with xemanagedbocreatepinmap via xebounpinmapnovm. Since the managed BO already has a devm cleanup...

CVE-2026-64517 drm/xe/gsc: Fix double-free of managed BO in error path

In the Linux kernel, the following vulnerability has been resolved: drm/xe/gsc: Fix double-free of managed BO in error path The error path in xegscinitposthwconfig explicitly frees a BO allocated with xemanagedbocreatepinmap via xebounpinmapnovm. Since the managed BO already has a devm cleanup...

CVE-2026-64516

The CVE-2026-64516 issue affects the Linux kernel’s DRM/AMDGPU VCE1 path. Root cause: the VCPU BO size did not account for the actual firmware offset, risking out-of-bounds access; fixes include subtracting the firmware offset from the firmware size, aligning stack and data offsets to the 32K TLB...

CVE-2026-64517

The CVE-2026-64517 entry describes a Linux kernel issue in the DRM/xe/gsc path where the error handling in xe_gsc_init_post_hwconfig() explicitly frees a managed BO with xe_bo_unpin_map_no_vm(), causing a double-free because a devm cleanup action is already registered. The fix is to remove the ex...
