In the Linux kernel, the following vulnerability has been resolved: media: rainshadow-cec: The TOCTOU race condition in raininterrupt has been fixed. In the interrupt handler raininterrupt, the check for buffer fullness on rain-buflen is performed before acquiring rain-buflock. This creates a...

CVE-2026-98047 bpf: Check ancestor frames for rbtree callbacks

In the Linux kernel, the following vulnerability has been resolved: bpf: Check ancestor frames for rbtree callbacks bpfrbtreeadd invokes its comparator while the caller holds the root lock. The native insertion code retains raw parent and link pointers across the callback, so the verifier prohibi...

CVE-2026-98047

The Linux kernel contains a vulnerability in the BPF subsystem where bpf_rbtree_add() fails to properly enforce callback restrictions during nested static subprogram calls. Because in_rbtree_lock_required_cb() only checks the innermost verifier frame, a subprogram can push a frame without the in_...

In the Linux kernel, the following vulnerability has been resolved: net: au1000: move free irq out of the close-time spinlocked section au1000 close calls free irq while aup-lock is still held with spin lock irqsave. free irq can sleep because it takes the IRQ descriptor request mutex, so it does...

SUSE CVE-2026-90317

In the Linux kernel, the following vulnerability has been resolved: bpf: Invalidate RCU pointers after final spin unlock In a sleepable BPF program, a spin lock can provide the only RCU protection for a kptr. The final bpfspinunlock ends that protection, but the verifier leaves the pointer valid...

PT-2026-94665

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description In sleepable BPF programs, a spin lock may serve as the sole RCU Read-Copy-Update protection for a kptr. The bpf spin unlock function ends this protection, but the verifier incorrectly...
