CVE-2022-50181

CVE-2022-50181 affects the Linux kernel’s virtio-gpu driver. The vulnerability arises from a missing NULL check in virtio_gpu_cmd_get_capset(), where a NULL-ified cache_ent could be dereferenced (ptr = cache_ent->caps_cache). This results in a NULL pointer dereference. The issue has been resol...

CVE-2022-50064

CVE-2022-50064 involves a use-after-free in the Linux kernel’s virtio-blk path. The issue arises because hctx->user_data is assigned to vq in virtblk_init_hctx(), but vq is freed during suspend and reallocated on resume, making hctx->user_data invalid after resume and capable of causing a k...
