CVE-2026-43473

CVE-2026-43473 affects the Linux kernel's mpi3mr SCSI driver. The vulnerability occurs when the driver cleans up resources and the reply/request queues are NULL due to memory being freed after a failed queue creation. The cleanup code may then dereference or mem-set freed memory, causing a system...

CVE-2026-43447

Summary: CVE-2026-43447 affects the Linux kernel iavf driver. A race condition arises when a PTP worker that caches PHC time is not stopped during adapter reset/disable, potentially freeing AQ-backed resources while the worker runs. If the worker calls into ptp commands during teardown, memory/lo...
