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...

CVE-2026-43071

A flaw was found in the Linux kernel's dcache component. When the 'dhashentries' parameter is set to one, an out-of-bounds OOB read occurs in the dentryhashtable. This issue arises due to an incorrect calculation of the 'dhashshift' value, causing the system to attempt to access unallocated memor...
