CVE-2026-98185
In the Linux kernel, the following vulnerability has been resolved:

wifi: mwifiex: validate scan response extents

mwifiex_ret_802_11_scan() subtracts the fixed response fields and the
firmware-provided BSS length from resp->size without first proving that
either extent fits. A short response or oversized BSS length can
therefore underflow tlv_buf_size and make the TLV parser walk beyond the
command response.

Compute the fixed extent from the selected normal or background scan
response. Validate that the fixed fields and BSS data fit before deriving
the TLV extent and entering the parser.
