Out-of-bounds read in Linux kernel - CVE-2026-68326

Vulnerability identifier: #VU141748

CSH Severity: Low

CVSS v4: 2.4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-68326

CWE-ID: CWE-125

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local attacker to disclose sensitive information.

The vulnerability exists due to an out-of-bounds read in mwifiex_process_uap_event() and the assoc_req_ies parsing path when processing a firmware-reported uAP association event with a crafted event length. A local attacker can supply a malicious or malformed event from a mwifiex device to disclose sensitive information.

The issue can be triggered by a malicious or malfunctioning mwifiex USB, SDIO, or PCIe device while the interface is operating in AP/uAP mode. An underflow in the calculated length may also cause stale event buffer bytes to be exposed through an NL80211_CMD_NEW_STATION notification.
