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...

PT-2026-38946

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in libceph where the system fails to properly verify the length of key material during decoding. Specifically, the process auth done function does not ensure that the key...

The vulnerability of the handle_auth_session_key() function in the net/ceph/auth_x.c module, which is part of the Linux kernel’s networking functions, allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the handleauthsessionkey function in the net/ceph/authx.c module, which is part of the Linux kernel’s networking functions, relates to buffer out-of-buffer writing. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...
