CVE-2026-80633

CVE-2026-80633 affects the Linux kernel 's iommufd subsystem. The root cause is that iopt_release_pages() calls dma_buf_unpin() without holding the exporter's dma_resv lock, as required by the function's assertion. This causes a kernel WARN to fire on every iommufd_ioas_destroy() or iommufd_ioas_...

CVE-2026-80628

CVE-2026-80628 is a data race in the Linux kernel's ALSA seq:oss subsystem. The function snd_seq_oss_readq_clear() resets the ring buffer state (qlen, head, tail) without holding q->lock, while concurrent reader/producer paths (snd_seq_oss_readq_free(), snd_seq_oss_readq_put_event()) serialize...

Implement a...

CVE-2026-80547

A flaw was found in the Linux kernel's s390/vfioccw component. This vulnerability arises from the lack of a proper lock to manage the list of Channel Report Word CRW payloads, which are asynchronous events from hardware. Without this lock, these payloads may not be read cohesively, potentially...

CVE-2026-80547

This vulnerability affects the Linux kernel 's s390/vfio_ccw subsystem (Virtual Function Interface for Channel-Word devices on the s390 architecture). The root cause is a missing lock on the CRW (Control Region Word) region, which handles asynchronous hardware events; without it, the list of payl...

CVE-2026-74733

A flaw was found in the Linux kernel's gpio: pca953x driver, which manages General Purpose Input/Output GPIO expanders. The driver uses its own locking mechanism, but the pca953xirqbussyncunlock function failed to acquire the necessary lock when performing register operations. This oversight coul...

CVE-2026-74646

A flaw was found in the Linux kernel's fastrpc subsystem. When an invoke operation is interrupted by a signal, the fastrpcinternalinvoke function moves memory mappings without properly holding the fl-lock. This missing lock during memory map manipulation creates a race condition, which could lead...
