Description

A use-after-free flaws was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to incorrect handling of the existing filter, leading to a kernel information leak issue. There are 3 CVEs for these flaws: CVE-2023-4206, CVE-2023-4207, CVE-2023-4208. The older one CVE-2023-4128 similar to these 3 (CVE-2023-4206, CVE-2023-4207, CVE-2023-4208) and the CVE-2023-4128 rejected as duplicate.
