The vulnerability of the tcf_exts_exec() function in the tcindex indexing filter of the tcindex traffic control system in Linux kernels allows a hacker to increase their privileges.

The vulnerability of the tcfextsexec function in the tcindex indexing filter of the tcindex traffic control system in Linux operating systems is related to the use of memory after it is freed during the processing of the tcfext parameter. Exploiting this vulnerability can allow an attacker to...

CVE-2023-1281

Use After Free vulnerability in Linux kernel traffic control index filter tcindex allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcfextsexec' is called with the destroyed tcfext. A local attacker user can u...
