Description
In the Linux kernel, the following vulnerability has been resolved:
vhost-vdpa: fix use after free in vhost_vdpa_probe()
The put_device() calls vhost_vdpa_release_dev() which calls
ida_simple_remove() and frees "v". So this call to
ida_simple_remove() is a use after free and a double free.
Affected configurations
• linux linux kernel (>= 6.0 < 6.1.64)
• linux linux kernel (>= 6.2 < 6.5.13)
• linux linux kernel (>= 6.6 < 6.6.3)
• linux linux kernel 6.7
