Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the
otx2 tc add flow() function within the octeontx2-pf module. The issue involves a potential use-after-free condition where memory is freed using kfree rcu() and then dereferenced before the free operation is completed. This occurs due to the order of operations, specifically dereferencing a node after queuing it for free, potentially leading to instability or unexpected behavior.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
