1) Out-of-bounds read (CVE-ID: CVE-2026-68352)
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:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local attacker to disclose sensitive information.
The vulnerability exists due to out-of-bounds read in ath6kl_wmi_connect_event_rx() when parsing firmware-controlled connect event information elements. A local attacker can supply crafted length fields to trigger out-of-bounds reads and disclose sensitive information.
The issue can also corrupt the wmi->is_wmm_enabled state during parsing.
Remediation
