CVE-2026-80633

In the Linux kernel, the following vulnerability has been resolved: iommufd: Take dmaresv lock before dmabufunpin in release path dmabufunpin requires the caller to hold the exporter's dmaresv lock: void dmabufunpinstruct dmabufattachment attach ... dmaresvasserthelddmabuf-resv;...

CVE-2026-80633

CVE-2026-80633 is a locking bug in the Linux kernel iommufd subsystem. The function iopt_release_pages() calls dma_buf_unpin() without holding the required dma_resv lock, causing a kernel WARN every time iommufd_ioas_destroy() or iommufd_ioas_unmap() releases the last reference on a DMABUF-backed...

CVE-2026-80628

CVE-2026-80628 is a data race in the Linux kernel's ALSA sequencer OSS subsystem. The function snd_seq_oss_readq_clear() resets ring queue state (qlen, head, tail) without holding the q->lock spinlock, while the normal reader and producer paths serialize the same state under that lock. This ra...
