Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-98348)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 0 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to trigger an out-of-bounds read.

The vulnerability exists due to unsigned length arithmetic wrapping in libipw_handle_assoc_resp() when processing association response frames shorter than the 30-byte fixed prefix. A remote attacker can send a truncated association response frame to trigger an out-of-bounds read.

The ipw2100 and ipw2200 management receive paths check only for the generic 24-byte three-address header before reaching this function. The wrapped length is truncated to a 16-bit value near 64 KiB and passed to libipw_parse_info_param(), which reads beyond the receive buffer.
