kernel: Use-after-free vulnerability in the Linux Kernel traffic control index filter

A use-after-free vulnerability was found in the traffic control index filter tcindex in the Linux kernel. The tcindexdelete does not properly deactivate filters, which can later lead to double freeing the structure. This flaw allows a local attacker to cause a use-after-free problem, leading to...

USN-6312-1 linux-gke, linux-ibm-5.4 vulnerabilities
