CVE-2026-31526 bpf: Fix exception exit lock checking for subprogs

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix exception exit lock checking for subprogs processbpfexitfull passes checklock = !curframe to checkresourceleak, which is false in cases when bpfthrow is called from a static subprog. This makes checkresourceleak to skip...

CVE-2026-31526

Summary: CVE-2026-31526 concerns the Linux kernel BPF verifier. A defect in exception exits for BPF subprograms allowed ORC unwinding to proceed without releasing user-held locks, risking resource leaks and instability. The root cause: process_bpf_exit_full() could set check_lock=false for except...

CVE-2026-31509 nfc: nci: fix circular locking dependency in nci_close_device

In the Linux kernel, the following vulnerability has been resolved: nfc: nci: fix circular locking dependency in nciclosedevice nciclosedevice flushes rxwq and txwq while holding reqlock. This causes a circular locking dependency because ncirxwork running on rxwq can end up taking reqlock too:...

CVE-2026-31509

CVE-2026-31509 affects the Linux kernel NFC NCI subsystem. The vulnerability stems from nci_close_device() flushing rx_wq and tx_wq while holding req_lock, creating a circular locking dependency with nci_rx_work() and related paths. The fix moves the rx_wq flush to after req_lock is released, rel...
