kernel: drm/amdkfd: Add TLB flush after MES queue eviction/suspension

A flaw was found in the Linux kernel's drm/amdkfd component. This vulnerability arises from a race condition where the Micro Engine Scheduler MES fails to perform a necessary Translation Lookaside Buffer TLB invalidation after unmapping queues. This oversight allows in-flight Direct Memory Access...

kernel: openvswitch: defer tunnel netdev_put to RCU release

A flaw was found in the Linux kernel's Open vSwitch OVS component. A race condition can occur during the destruction of a network device netdev tunnel, where the ovsnetdevtunneldestroy function may attempt to release a device reference while other parts of the system are still actively using it...

kernel: wifi: mac80211: defer link RX stats percpu free to RCU

A flaw was found in the mac80211 Wi-Fi driver of the Linux kernel. When an MLO Multi-Link Operation link is removed, the RX statistics per-CPU buffer is freed immediately, while the link container is deferred to RCU Read-Copy-Update. This timing issue can lead to a use-after-free vulnerability,...

kernel: drm/vmwgfx: use check_add_overflow for shader size+offset bound

A flaw was found in the drm/vmwgfx component of the Linux kernel. An integer overflow vulnerability exists in the vmwshaderdefine function due to improper validation of user-supplied shader window size and offset. When the offset value is close to its maximum, an unsigned addition can wrap around...

kernel: drm/amdgpu/vce: fix integer overflow in image size

A flaw was found in the drm/amdgpu/vce component of the Linux kernel. Malicious VCE Video Codec Engine command streams with oversized dimensions can cause a 32-bit integer overflow. This overflow bypasses validation, allowing the GPU firmware to perform out-of-bound memory access. This could lead...
