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...
