CVSS: 8.6EPSS: 0%CPEs: 27EXPL: 2CVE-2022-1055 – Use after Free in tc_new_tfilter allowing for privilege escalation in Linux Kernel
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 •

CVSS: 8.2EPSS: 0%CPEs: 6EXPL: 2CVE-2021-4120 – snapd could be made to bypass intended access restrictions through snap content interfaces and layout paths
https://notcve.org/view.php?id=CVE-2021-4120
snapd 2.54.2 fails to perform sufficient validation of snap content interface and layout paths, resulting in the ability for snaps to inject arbitrary AppArmor policy rules via malformed content interface and layout declarations and hence escape strict snap confinement. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 snapd versión 2.54.2, no lleva a cabo una comprobación suficiente de la interfaz de contenido de snap y de las rutas de diseño, resultando en una posibilidad de que los snaps inyecten reglas de política de AppArmor arbitrarias por medio de declaraciones de interfaz de contenido y de diseño mal formadas y, por tanto, escapen al confinamiento estricto de snap.
