In the Linux kernel, the following vulnerability has been resolved:
netlink: add nla be16/32 types to minlen array
BUG: KMSAN: uninit-value in nla_validate_range_unsigned lib/nlattr.c:222 [inline] BUG: KMSAN: uninit-value in nla_validate_int_range lib/nlattr.c:336 [inline] BUG: KMSAN: uninit-value in validate_nla lib/nlattr.c:575 [inline] BUG: KMSAN: uninit-value in __nla_validate_parse+0x2e20/0x45c0 lib/nlattr.c:631 nla_validate_range_unsigned lib/nlattr.c:222 [inline] nla_validate_int_range lib/nlattr.c:336 [inline] validate_nla lib/nlattr.c:575 [inline] ...
The message in question matches this policy:
[NFTA_TARGET_REV] = NLA_POLICY_MAX(NLA_BE32, 255),
but because NLA_BE32 size in minlen array is 0, the validation code will read past the malformed (too small) attribute.
Note: Other attributes, e.g. BITFIELD32, SINT, UINT.. are also missing: those likely should be added too.
