The nla_ok() added by commit c96adff956191 (\"cls_flower:call nla_ok() before nla_next()\") only validates the mask pointerthat was just consumed; the pointer produced by nla_next() is used bythe next iteration (fl_set_geneve_opt() and siblings) without anyvalidation.\nThe mask's nested attributes are validated with NL_VALIDATE_LIBERAL,which merely warns on trailing bytes that do not form a completeattribute.  A mask carrying one valid attribute plus 1-3 residuebytes (or a non-aligned attribute length making msk_depth negative)therefore reaches the next iteration with msk_depth != 0, so neitherthe !msk_depth check in fl_set_enc_opt() nor the !depth check in theper-type helpers fires.  nla_type() then reads past the mask payloadand nla_parse_nested_deprecated() iterates with an nla_len takenfrom those bytes, reading well beyond the mask attribute (KASAN:slab-out-of-bounds read in __nla_validate_parse from fl_change()).\nValidate the advanced mask pointer as well: when the mask is notlegitimately exhausted (msk_depth != 0) and the new pointer failsnla_ok(), reject the filter with -EINVAL.  An exactly exhausted maskstill skips the check, preserving exact-match behaviour for theremaining key attributes.\nhttps://www.cve.org/CVERecord?id=CVE-2026-99112https://git.kernel.org/stable/c/45e60747a9db2307929260d9aa9c1c6cbb70ee77https://git.kernel.org/stable/c/bb187146c7e5c666874784e4f3fc1bc5126e6e92https://git.kernel.org/stable/c/fee10655709c5c597e8e9f722f3035d9ea31ff3a#kernel
