Description

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 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2.

Affected configurations

• linux linux kernel (>= 4.14 < 5.10.169) • linux linux kernel (>= 5.11 < 5.15.95) • linux linux kernel (>= 5.16 < 6.1.13) • linux linux kernel 6.2
