CVE-2026-89646

A flaw was found in the Ceph filesystem component of the Linux kernel. When a writeback operation is aborted during an unmount process, a reference to an inode a data structure describing a filesystem object is not properly released. This prevents the inode from being evicted, potentially leading...

CVE-2026-89653

A flaw was found in the Linux kernel's Ceph filesystem. This vulnerability occurs when a malicious or malformed MDSMap exporttargets entry, controlled by a monitor, contains a rank value that exceeds the maximum allowed CEPHMAXMDS during the decoding process. This can lead to an out-of-bounds...

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...

In the Linux kernel, the following vulnerability has been resolved: ceph: fix leaked inode reference on writeback abort at umount cephdirtyfolio takes a wrbuffer claim on each newly dirtied folio: it bumps iwrbufferref taking an ihold on the 0-1 transition and attaches the snapcontext to...

CVE-2026-89647

In the Linux kernel, the following vulnerability has been resolved: ceph: do not repeat cephtrimdentries if no progress possible cephcapreclaimwork re-queues itself for as long as cephtrimdentries returns -EAGAIN, which happens whenever a lease walk exhausts its nrtoscan budget. This creates a bu...

CVE-2026-89648

In the Linux kernel, the following vulnerability has been resolved: ceph: cap delegated inode count in cephparsedeleginos cephparsedeleginos decodes interval sets of delegated inode numbers from an MDS create-with-delegation reply. For each set it reads a 64-bit start and a 64-bit len with...

CVE-2026-89652 ceph: bound copied dentry name length in NFS export get_name

In the Linux kernel, the following vulnerability has been resolved: ceph: bound copied dentry name length in NFS export getname cephgetname copies the MDS-supplied name into the caller's NAMEMAX-sized buffer with memcpyname, rinfo-dname, rinfo-dnamelen and then writes namerinfo-dnamelen = 0,...

CVE-2026-89648

CVE-2026-89648 affects the Linux kernel Ceph filesystem client . The vulnerable function, ceph_parse_deleg_inos() , decodes delegated inode interval sets from MDS replies but performs no bounds check on the 64-bit len field, which is fully attacker-controlled. A malicious or compromised Ceph MDS ...

CVE-2026-89647 ceph: do not repeat ceph_trim_dentries() if no progress possible

In the Linux kernel, the following vulnerability has been resolved: ceph: do not repeat cephtrimdentries if no progress possible cephcapreclaimwork re-queues itself for as long as cephtrimdentries returns -EAGAIN, which happens whenever a lease walk exhausts its nrtoscan budget. This creates a bu...

CVE-2026-89647

CVE-2026-89647 is a Linux kernel vulnerability in the Ceph filesystem driver. The root cause is a busy loop in ceph_cap_reclaim_work(): it re-queues itself whenever ceph_trim_dentries() returns -EAGAIN, which occurs when a lease walk exhausts its scan budget without freeing anything. The dir-leas...
