CVE-2026-72034

A flaw was found in the Linux kernel's file handle fhandle mechanism. A local attacker could exploit a vulnerability in the capablewrtmount function, which incorrectly handles detached mounts. By performing specific operations, an attacker could trigger a null pointer dereference, leading to a...

CVE-2026-72034

In the Linux kernel, the following vulnerability has been resolved: fhandle: reject detached mounts in capablewrtmount The recent fhandle RCU fix moved the mount namespace capability check into capablewrtmount, so a non-NULL mntnamespace survives the nscapable dereference. The helper still assume...
