Linux Kernel CVE-2026-53257

The primary fix is to upgrade to Linux kernel 7.0.13 or the patched 7.1 mainline release, applying stable commits 0f5e9ddd7e8e7758771a63cdd498a2007dc8da7a and cb9959ab5f99611d27a06586add84811fe8102dc (available at https://git.kernel.org/stable/c/). Distribution-specific stable kernels incorporating these commits should be applied as available. As a compensating control where patching is not immediately possible, disabling EHT/Wi-Fi 7 support via driver module parameters or blacklisting the affected wireless driver prevents the vulnerable code path from executing, at the cost of reducing Wi-Fi performance to 802.11ax (Wi-Fi 6/6E) speeds. On multi-user systems, restricting unprivileged user access to wireless subsystem controls (e.g., via udev rules or MAC policy) reduces exposure consistent with the PR:L requirement in the CVSS vector. No special considerations apply to systems without Wi-Fi 7 hardware, as they cannot reach the affected code path.
