Out-of-bounds read in Linux kernel - CVE-2026-80722

Vulnerability identifier: #VU146056

CSH Severity: Medium

CVSS v4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-80722

CWE-ID: CWE-125

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to an out-of-bounds read in mac80211 TWT setup handling when processing a received S1G TWT setup frame. A remote attacker can send a specially crafted TWT setup frame with an individual agreement and a truncated parameters block to cause a denial of service.

Broadcast agreements are rejected locally after accessing only req_type.
