CVE-2026-80953

A flaw was found in the Linux kernel's i3c master driver. A race condition exists where the adi_i3c_master_probe() function requests an interrupt and unmasks a register before a critical lock (xferqueue.lock) is properly initialized. This allows a pending interrupt to attempt to acquire an uninitialized lock, which can lead to a kernel crash and a denial of service. This issue can be triggered by a local attacker.
