CVE-2026-68160

Summary: CVE-2026-68160 is a pre-auth, out-of-bounds read vulnerability in the Linux kernel’s Ceph code path (ceph_handle_caps) caused by using attacker-controlled snap_trace_len to compute an end pointer without proper bounds checks. The issue can lead to out-of-bounds reads of encoded snap data...

CVE-2026-68159 libceph: bound pg_{temp,upmap,upmap_items} length to CEPH_PG_MAX_SIZE

In the Linux kernel, the following vulnerability has been resolved: libceph: bound pgtemp,upmap,upmapitems length to CEPHPGMAXSIZE decodepgtemp decodes an user-controlled length but only rejects values large enough to overflow the allocation; it does not bound it to CEPHPGMAXSIZE. The helper back...

CVE-2026-68159

CVE-2026-68159 (Linux kernel libceph bound check) : The issue occurs when decoding pg_temp/pg_upmap entries in libceph within the kernel. __decode_pg_temp() may accept a user-controlled length that overflows the allocation, and the same applies to __decode_pg_upmap_items(); decoded data is later ...

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...
