CVE-2026-80558

This Linux kernel vulnerability affects the libceph subsystem. A corrupted osdmap received from a Ceph monitor or OSD may contain OSD indices in its primary_temp field that are greater than max_osd or smaller than CEPH_HOMELESS_OSD (-1). While most OSD indices in the osdmap are validated, the one...

CVE-2026-80557 libceph: fix OOB read in decode_watchers() via missing bounds check

In the Linux kernel, the following vulnerability has been resolved: libceph: fix OOB read in decodewatchers via missing bounds check cephstartdecoding validates that structlen bytes remain in the buffer after the encoding header, but accepts structlen=0 as valid: cephdecodeneedp, end, 0, bad alwa...

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...
