CVE-2026-46061

Summary: CVE-2026-46061 is a Linux kernel issue in jbd2/journal handling that can cause an ABBA deadlock when filesystem blocksize is smaller than pagesize. The root cause is a lock-order conflict introduced by switching to __find_get_block_nonatomic() which can hold folio and buffer locks in the...

CVE-2026-46052

The CVE-2026-46052 issue concerns the Linux kernel Ceph filesystem where a negative dentry that is already hashed can be re-added to the dcache, corrupting the d_hash bucket and leading to an RCU stall or system hang. The root cause is that d_add() can rehash and reinstate a dentry that is alread...

CVE-2026-46052

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...
