CVE-2026-53392 NFSv4/flexfiles: reject zero filehandle version count

In the Linux kernel, the following vulnerability has been resolved: NFSv4/flexfiles: reject zero filehandle version count fflayoutalloclseg decodes the filehandle-version array count from the flexfiles layout body. The value is used as the count for kzallocobjs, and the current code only rejects...

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...
