CVE-2026-43304

CVE-2026-43304 affects the Linux kernel libceph component. The flaw arises when decoding key material in process_auth_done(), where the code failed to enforce an upper bound on key length. The fix defines and enforces CEPH_MAX_KEY_LEN and clamps key material to a fixed-size buffer, addressing a v...

kernel: out-of-bound read in memcpy_fromiovecend()

A flaw was found in the Linux kernel that allows the userspace to call memcpyfromiovecend and similar functions with a zero offset and buffer length. This can cause a read beyond the buffer boundaries flaw and, in certain cases, cause a memory access fault and a system halt by accessing invalid...
