PT-2026-72749

In the Linux kernel, the following vulnerability has been resolved: vduse: hold vduse lock across IDR lookup in open path vduse dev open looks up struct vduse dev through the IDR and then acquires dev-lock only after vduse lock has been dropped. This leaves a window where a concurrent VDUSE DESTR...

CVE-2026-68424

CVE-2026-68424 affects the Linux kernel MTD virt_concat code. The root cause is a use-after-free: mtd_concat_destroy() frees item->concat, so calling mtd_virt_concat_put_mtd_devices(item->concat) can use freed memory. The fix migrates the call to mtd_virt_concat_put_mtd_devices() to occur b...

CVE-2026-68423

The vulnerability CVE-2026-68423 concerns the Linux kernel’s MTD subsystem, specifically the virt_concat code path. A use-after-free occurs in mtd_virt_concat_destroy() because mtd_concat_destroy() frees item->concat, after which mtd_virt_concat_put_mtd_devices(item->concat) may be invoked,...

CVE-2026-68191

The CVE reports a NULL pointer dereference in the Linux kernel’s ath12k wifi driver during unbind, when irq_work_sync() from rhashtable_destroy() runs if hash tables were never fully initialized. Two affected hash tables are ath12k_link_sta (ath12k_base) and ath12k_dp_link_peer (ath12k_dp). The r...
