CVE-2026-68293 net/mlx5: Fix MCIA register buffer overflow on 32 dword reads

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix MCIA register buffer overflow on 32 dword reads The MCIA register can return up to 32 dwords 128 bytes when the device advertises the mcia32dwords capability, but struct mlx5ifcmciaregbits only defines dword0..11,...

CVE-2026-68293

Summary (CVE-2026-68293) : A Linux kernel vulnerability in the net/mlx5 driver allows a buffer overflow when reading the MCIA register on devices advertising the mcia_32dwords capability. The function mlx5_query_mcia() may copy more bytes than the allocated output buffer, due to a mismatch betwee...

CVE-2026-68276 drm/amdgpu/gfx: fix cleaner shader IB buffer overflow

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx: fix cleaner shader IB buffer overflow The cleaner shader sysfs path allocates a 16-dword 64 byte IB but incorrectly fills alignmask + 1 dwords. On GFX rings alignmask is 0xff, so the loop wrote 256 dwords into a...

CVE-2026-68276

The CVE affects the Linux kernel driver path drm/amdgpu/gfx. The cleaner shader sysfs path allocated a 16-dword (64-byte) IB but incorrectly filled (align_mask + 1) dwords; with align_mask 0xff, the loop wrote 256 dwords into a 64-byte buffer, causing a kernel page fault. The fix is to fill 16 dw...
