In the Linux kernel, the following vulnerability has been resolved:
virtiofs: fix memory leak in virtio_fs_probe()
When accidentally passing twice the same tag to qemu, kmemleak ended up reporting a memory leak in virtiofs. Also, looking at the log I saw the following error (that's when I realised the duplicated tag):
virtiofs: probe of virtio5 failed with error -17
Here's the kmemleak log for reference:
