CVE-2026-68156

The CVE-2026-68156 issue affects the Linux kernel libceph path: during an authorizer update, ceph_x_update_authorizer() may rebuild the authorizer and, if the new authorizer won’t fit in the existing buffer, it frees the old buffer while auth->authorizer_buf still points to the freed memory. A...

CVE-2026-68154

The CVE-2026-68154 vulnerability affects the Linux kernel’s libceph component, where CRUSH map decoding accepts bucket type 0 (reserved for devices) can let a malformed map cause a negative bucket ID to index the OSD weight array, leading to denial of service. The issue is fixed by rejecting zero...

CVE-2026-68109

CVE-2026-68109 : In the Linux kernel’s drm/amdgpu/sdma7.1 path, the vulnerability was resolved by replacing a failing assertion: replace BUG_ON() with WARN_ON() so the kernel no longer crashes in these cases. The commit cherry-picks the fix (c4f230b51cf2d3e7e8b1c800331f3dbed2a9e3f5). Affected com...

CVE-2026-68108

In CVE-2026-68108, the Linux kernel component drm/amdgpu/vce is vulnerable to a 32-bit integer overflow when processing VCE command streams with oversized dimensions (e.g., 65536×65536), allowing out-of-bounds memory access by the GPU firmware. The issue is addressed by using 64-bit arithmetic to...
