Overview
Affected versions of this package are vulnerable to Reachable Assertion in the rxrpc_service_prealloc_one process. An attacker can cause assertion failures and potential denial of service by triggering a preallocation collision with duplicate call IDs during AF_RXRPC server operations.
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
