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

Description A vulnerability in the Linux kernel has been resolved, related to the transmission of isotp PDUs. The issue arose from a single timer handling two functions: sending consecutive frames with a time gap and monitoring timeouts for flow control and echo frames. This led to larger txstate checks and potentially caused a problem discovered by syzbot, enabling the panic on warn feature during testing. The resolution involved splitting the former 'txtimer' function into 'txfrtimer' and 'txtimer' to handle these functionalities separately, resulting in simplified timers running in one-shot mode and improved state transitions.

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