CVE-2026-74468

A flaw was found in the Linux kernel's GPIO PCH driver. On systems configured with PREEMPTRT, a local attacker could trigger a specific interrupt handler pchirqtype in a non-sleepable context. This improper use of a spinlock, which attempts to acquire a sleeping lock in an atomic context, can lea...
