Out-of-bounds read in Linux kernel - CVE-2026-92497

Vulnerability identifier: #VU151014

CSH Severity: Low

CVSS v4: 1.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-92497

CWE-ID: CWE-125

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local privileged user to cause an out-of-bounds read.

The vulnerability exists due to improper bounds checking in ath12k_wmi_op_rx() when processing a firmware buffer that is shorter than a WMI command header. A local privileged user can cause the function to access header data in an undersized firmware buffer to cause an out-of-bounds read.
