kernel: libceph: make decode_pool() more resilient against corrupted osdmaps

In the Linux kernel, the following vulnerability has been resolved: libceph: make decodepool more resilient against corrupted osdmaps If the osdmap is maliciously corrupted such that the encoded length of cephpgpool envelope is less than what is expected for a particular encoding version,...

kernel: libceph: fix potential use-after-free in have_mon_and_osd_map()

A use-after-free vulnerability was found in the Ceph client session initialization in the Linux kernel. The havemonandosdmap function checks map epochs without holding the appropriate locks, racing with concurrent map updates that free the old map. This can result in dereferencing freed memory...

UBUNTU-CVE-2025-68285

In the Linux kernel, the following vulnerability has been resolved: libceph: fix potential use-after-free in havemonandosdmap The wait loop in cephopensession can race with the client receiving a new monmap or osdmap shortly after the initial map is received. Both cephmonchandlemap and handleonem...
