CVE-2026-45880 PCI/P2PDMA: Release per-CPU pgmap ref when vm_insert_page() fails

In the Linux kernel, the following vulnerability has been resolved: PCI/P2PDMA: Release per-CPU pgmap ref when vminsertpage fails When vminsertpage fails in p2pmemallocmmap, p2pmemallocmmap doesn't invoke percpurefput to free the per-CPU ref of pgmap acquired after genpoolallocowner, and...

CVE-2026-45880

The CVE-2026-45880 entry concerns the Linux kernel PCI/P2PDMA path. When vm_insert_page() fails inside p2pmem_alloc_mmap(), the code path does not call percpu_ref_put() to release the per-CPU reference of the pgmap acquired after gen_pool_alloc_owner(). As a result, memunmap_pages() can hang inde...

CVE-2026-45874

The CVE-2026-45874 entry concerns the Linux kernel component for Freescale IMX8QM HSIO. The vulnerability arises when probing the driver: the refclk_pad pointer may be NULL if the device tree property fsl,refclk-pad-mode is not defined, yet imx_hsio_configure_clk_pad() uses this pointer unconditi...

CVE-2026-45866

The CVE-2026-45866 issue is a use-after-free in caif_serial within the Linux kernel where handle_tx() may access ser->tty after the tty is freed due to tty_kref_put() occurring in ldisc_close() while the network device is still active. The race between ldisc_close() and packet transmission can...
