CVE-2026-80817

A NULL pointer dereference in the Linux kernel's iommu/iommufd subsystem (drivers/iommufd/ioas.c) can cause a kernel crash. The root cause is a race condition : iopt_map_pages() inserts an IOAS area into the interval tree with area->pages still NULL, then later fills it under a different lock....

CVE-2026-80743

CVE-2026-80743 affects the Linux kernel's ASoC xilinx formatter_pcm driver . The root cause is a race condition: IRQ handlers call dev_get_drvdata() to retrieve driver data, but that data is only assigned at the end of the probe function—after devm_request_irq(). If an interrupt fires in that win...
