Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue is related to a use-after-free vulnerability in the net/sched subsystem of the Linux kernel. Specifically, the
tcf ct flow table process conn function may access memory after it has been freed, leading to a slab-use-after-free error. This can occur when a clash is resolved but the ct object is still passed to the tcf ct flow table process conn function for further processing. The vulnerability can be fixed by retrieving the ct object from the skb again after confirming the conntrack.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
