Linux Kernel wlcore EUVD-2026-25445

Vendor-released patches are available for all affected stable kernel branches. Upgrade to patched versions: 5.10.253+, 5.15.203+, 6.1.167+, 6.6.130+, 6.12.78+, 6.18.20+, 6.19.10+, or mainline 7.0+. Patch references and commits available at https://git.kernel.org/stable/ with specific fix commits listed in References section. For systems unable to immediately patch, the following compensating controls provide limited mitigation with noted trade-offs: (1) Disable the wlcore wireless driver via modprobe blacklist (add 'blacklist wlcore' to /etc/modprobe.d/blacklist.conf) - this prevents the vulnerable code path entirely but eliminates wireless functionality on affected hardware, requiring alternative network connectivity via Ethernet or external USB wireless adapters. (2) Implement memory pressure monitoring and proactive system restarts when available memory drops below operational thresholds - this reduces exploit window duration but does not prevent the vulnerability and introduces service interruption. (3) Deploy kernel watchdog timers with aggressive soft lockup detection thresholds to force system recovery - this limits DoS duration to watchdog timeout period (typically 20-60 seconds) but results in unclean reboots and potential data loss. These workarounds are inferior to patching and should only be temporary measures for systems in patch testing cycles or requiring change approval windows.
