Overview
Affected versions of this package are vulnerable to Use After Free in the mmc_hsq_pump_requests process when request_atomic returns -EBUSY, leading to retry_work being queued. If the driver is removed while work is still pending, the work may execute after the associated memory has been freed, resulting in dereferencing freed memory. An attacker can potentially cause system instability or execute arbitrary code by triggering driver removal while work is pending.
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
