CVE-2026-43407

The CVE-2026-43407 issue affects the Linux kernel libceph component, where a CEPH_MSG_AUTH_REPLY with a large payload_len could trigger an integer overflow and out-of-bounds read. The root cause is storing payload_len and related lengths in int, allowing negative values to underflow pointers. The...

CVE-2026-43406

CVE-2026-43406 affects the Linux kernel libceph component. The issue is in process_message_header() where, if a message frame is corrupted or misrepresented, an out-of-bounds read may occur due to a missing explicit bounds check before decoding the header. The vulnerability can enable remote expl...
