In the Linux kernel, the following vulnerability has been resolved:

wifi: libipw: reject too-short beacon and probe responses

libipw_process_probe_response() and the libipw_network_init() call it
makes assume the frame contains the full 36-byte beacon and probe
response prefix, but the ipw2100 and ipw2200 receive paths only
establish that a management frame carries the generic 24-byte
three-address header.

libipw_network_init() then computes the information element length as

	stats->len - sizeof(*beacon)

stats->len is a u16 and sizeof() has type size_t, so the subtraction is
evaluated as size_t and wraps instead of going negative.  Truncating
that to the u16 length parameter of libipw_parse_info_param() yields
65524 for a 24-byte beacon, and the parser then walks the receive
buffer as if it held almost 64 KiB of information elements, reading
past the allocation.

Reject the frame before any fixed field is touched.

Found by an AI-assisted review of length arithmetic in management frame
parsers.  Verified with a KUnit case under Generic KASAN on arm64 under
QEMU; I do not have the hardware, so it is not tested on a real device.
