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...

CVE-2026-23467

CVE-2026-23467 affects the Linux kernel drm/i915/dmc driver. The vulnerability is a NULL pointer dereference that can occur during probe when DC6 is unexpectedly enabled, due to intel_power_domains_init_hw() calling intel_dmc_update_dc6_allowed_count() before intel_dmc_init(). The root cause is u...
