CVE-2026-89649

A flaw was found in the Linux kernel's Ceph file system CephFS component. A malicious or compromised metadata server can manipulate the length of an extended attribute xattr value, causing the system to read beyond the intended memory boundary. This out-of-bounds read allows a local user to acces...

CVE-2026-89649

This out-of-bounds read affects the Linux kernel's CephFS client , specifically the __build_xattrs() function. When decoding the xattr blob supplied by a Ceph metadata server (MDS), the 32-bit value length of the final attribute is never validated against the blob size via a ceph_decode_need() ch...

CVE-2026-53799

A symlink race condition in rsync allows a local attacker to achieve privilege escalation. By substituting a symlink at a predictable destination path between a file write and the application of access control lists ACLs or extended attributes xattrs, an attacker can redirect these permissions to...

CVE-2026-80809

CVE-2026-80809 affects the Linux kernel's ocfs2 filesystem . The root cause is that ocfs2_calc_xattr_set_need() fails to reserve metadata blocks for a new xattr value's extent tree when the file already has an external xattr block, leaving meta_ac as NULL. On a fragmented filesystem , this causes...

CVE-2026-80808

CVE-2026-80808 affects the Linux kernel ext4 filesystem. The bug is in ext4_xattr_block_set() , which retries indefinitely when an mbcache entry selected for reuse has a saturated reference count (≥ EXT4_XATTR_REFCOUNT_MAX , 1024). Normally this invariant holds because the count and MBE_REUSABLE_...
