10

High

VectorAV:N/AC:L/Au:N/C:C/I:C/A:C
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.
