Overview
Affected versions of this package are vulnerable to Use After Free in the run_deferred process. An attacker can trigger a read of freed memory by exploiting a race condition between deferred request handling and the RCU grace period, potentially leading to system instability or execution of arbitrary code.
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
