CVE-2023-53218

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains an issue where a process waiting for an rxrpc call could be interrupted, leading to subsequent sendmsg() calls failing with an EBUSY error until an assignment is made. The fix allows the call to be aborted without failing due to EBUSY. This occurs when sendmsg() creates an rxrpc call and queues it while waiting for a connection and channel assignment, as the encrypted DATA packet content includes a summary of the connection parameters.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
