CVE-2026-53392

CVE-2026-53392 affects the Linux kernel’s NFSv4/flexfiles path. The flaw arises in ff_layout_alloc_lseg(), which decodes the filehandle-version array count and uses it to allocate with kzalloc_objs(). A zero count can yield ZERO_SIZE_PTR and get stored in dss_info->fh_versions, while later fle...

CVE-2026-53385

CVE-2026-53385 relates to a Linux kernel issue in vc_screen where a race in vcs_write() can yield a stale vc_data after the console_lock is dropped and re-acquired. If the vc has been deallocated in the interim, a subsequent call to vcs_scr_updated() uses a NULL vc, causing a null-pointer derefer...

CVE-2026-53381

The CVE-2026-53381 issue affects the Linux kernel’s virtiofs path for submount umount. The root cause is a use-after-free (UAF) in iput() invoked from fuse_release_end() when the superblock has already been destroyed; the existing safeguard (wait for num_waiting to drop to zero) only covered the ...
