01 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: caif_virtio: fix wrong pointer check in cfv_probe() del_vqs() frees virtqueues, therefore cfv->vq_tx pointer should be checked for NULL before calling it, not cfv->vdev. Also the current implementation is redundant because the pointer cfv->vdev is dereferenced before it is checked for NULL. Fix this by checking cfv->vq_tx for NULL instead of cfv->vdev before calling del_vqs(). In the Linux kernel, the following vulnerability has been resolv... • https://git.kernel.org/stable/c/0d2e1a2926b1839a4b74519e660739b2566c9386 •
