CVE-2026-46052

A flaw was found in the Linux kernel's Ceph filesystem. A local user or process interacting with the Ceph filesystem could trigger a dcache hash corruption when a negative dentry is incorrectly re-added to the dcache hash while it is already present. This can cause the system to experience an RCU...

EUVD-2026-32434

In the Linux kernel, the following vulnerability has been resolved: ceph: only dadd negative dentries when they are unhashed Ceph can call dadddentry, NULL on a negative dentry that is already present in the primary dcache hash. In the current VFS that is not safe. dadd goes through dadd to...

PT-2026-43919

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the Ceph component of the Linux kernel where d add can be called on a negative dentry that is already present in the primary dcache hash. This occurs because certain...

CVE-2022-50385

CVE-2022-50385 affects the Linux kernel NFS automount path: when mounting from an NFSv4 referral, path->dentry can become a negative dentry, so the fix derives the struct nfs_server from the dentry itself. The vulnerability is an Oops (local impact) and is resolved in the kernel by this change...
