CVE-2026-80557

CVE-2026-80557 is a 4-byte out-of-bounds read in the Linux kernel's libceph client, specifically in decode_watchers(). The function calls ceph_decode_32(p) without a preceding bounds check; when a malicious or compromised OSD sends an obj_list_watch_response_t with struct_len=0, the pointer equal...
