Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-68350)

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

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local attacker to disclose sensitive information.

The vulnerability exists due to an out-of-bounds read in carl9170_tx_process_status() when processing firmware-controlled TX status entries. A local attacker can provide a crafted firmware response with an oversized hdr.ext value to disclose sensitive information.

The issue is caused by an off-by-two bounds check error that allows two extra iterations past valid _tx_status entries.
