Overview

Affected versions of this package are vulnerable to Use After Free in the vub300 process. An attacker can cause memory corruption or system instability by triggering a race condition between the probe error path and queued deadwork after a failure in mmc_add_host(). This is only exploitable if the mmc_add_host() operation fails and takes longer than one second to complete, allowing the inactivity timer to fire and deadwork to execute after the memory has been freed.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
