https://notcve.org/view.php?id=CVE-2022-1055
A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 se presenta un uso de memoria previamente liberada en el Kernel de Linux en la función tc_new_tfilter que podría permitir a un atacante local alcanzar una escalada de privilegios. La explotación requiere espacios de nombres de usuarios no privilegiados. Recomendamos actualizar el commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 A use-after-free vulnerability was found in the tc_new_tfilter function in net/sched/cls_api.c in the Linux kernel. • http://packetstormsecurity.com/files/167386/Kernel-Live-Patch-Security-Notice-LSN-0086-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 https://kernel.dance/#04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 https://security.netapp.com/advisory/ntap-20220506-0007 https://syzkaller.appspot.com/bug?id=2212474c958978ab86525fe6832ac8102c309ffc https://access.redhat.com/security/cve/CVE-2022-1055 https://bugzilla.redhat.com/show_bug.cgi?id=2070220 • CWE-416: Use After Free •
