CVE-2026-23165

CVE-2026-23165 affects the Linux kernel sfc (Solarflare) network driver. The issue is a deadlock when reading RSS config with ethtool -x because the driver locks the net_device rss_lock that is already held by the core; the fix is to remove the driver-side lock acquisition (deadlock avoidance). P...
