**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The vulnerability is related to the Linux kernel's TCP implementation, specifically with the initialization of the accept queue's spinlocks. The issue can cause a corrupted lock value, leading to a warning and potential system instability. The vulnerability can be triggered by running a reproduction C program locally, which causes the pvqspinlock to have a corrupted value. The issue is analyzed in the context of two threads, Thread A and Thread B, where Thread A receives an ACK TCP packet and Thread B shuts down the connection, leading to a disconnect. The vulnerability is related to the `inet csk reqsk queue add` function and the `tcp check req` function. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
