CVE-2026-89492

A flaw was found in the Linux kernel's OCFS2 filesystem. A local attacker with the ability to mount a crafted on-disk image could exploit this vulnerability by providing excessive directory-index entry counts when reading metadata. This can lead to an out-of-bounds read, potentially causing...

CVE-2026-89653

A flaw was found in the Linux kernel's Ceph file system client. When decoding metadata server maps MDSMap, the client fails to properly validate rank identifiers within export targets against protocol limits. A malicious or compromised Ceph storage monitor can send a crafted map that triggers an...

CVE-2026-89661

A flaw was found in the Linux kernel's Network File System Daemon NFSD. A local administrator with CAPSYSADMIN capabilities can trigger a use-after-free vulnerability by writing to /proc/fs/nfsd/unlockfilesystem after the NFSD server has shut down. This can lead to memory corruption, potentially...

CVE-2026-89647

A flaw was found in the Linux kernel's Ceph file system. The cephtrimdentries function, when invoked by cephcapreclaimwork, can enter an infinite loop under specific conditions where no leases need to be reclaimed. This busy loop causes excessive CPU utilization, potentially leading to a Denial o...

CVE-2026-89617

A flaw was found in the Linux kernel's NTFS3 filesystem driver. An attacker with local access could craft a malicious NTFS log file. During log replay, insufficient validation of the lcnsfollow field in a DIRPAGEENTRY could lead to an out-of-bounds write. This memory corruption could result in a...
