CVE-2026-23475
CVE-2026-23475 affects the Linux kernel SPI subsystem. The issue was a NULL pointer dereference window in per‑CPU controller statistics: stats were allocated only after controller registration with driver core, so early sysfs access could dereference NULL. The fix moves statistics allocation to t...
