CVE-2026-89990

A flaw was found in the Ceph filesystem module of the Linux kernel. A local attacker could trigger a use-after-free vulnerability in the cephmdscheckaccess function. This occurs when a concurrent session reopens and frees an array while it is still being accessed, leading to a system crash and...

CVE-2026-89990

This use-after-free vulnerability in the Linux kernel's Ceph filesystem driver occurs when ceph_mds_check_access() traverses the mdsc->s_cap_auths array without holding mdsc->mutex. A concurrent MDS session OPEN replaces and frees that array, so a racing file-open path (e.g. ceph_atomic_ope...

CVE-2024-56564: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ceph: pass cred pointer to cephmdsauthmatch This eliminates a redundant getcurrentcred call, because cephmdscheckaccess has already obtained this pointer. As a side effect, this also fixes a reference leak in cephmdsauthmatch: by...
