CVE-2024-35910

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

Description The vulnerability is related to the improper termination of timers for kernel sockets in the Linux kernel. When TCP sockets are closed, the function inet csk clear xmit timers() is called to stop the timers. However, this function can be called from any context, including when the socket lock is held, which can lead to ongoing timers finishing much later. For kernel sockets, this can cause the netns to be freed before the timer can complete, because kernel sockets do not hold a reference on the netns. The patch adds a new function inet csk clear xmit timers sync() that uses sk stop timer sync() to ensure all timers are terminated before the kernel socket is released.

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