https://notcve.org/view.php?id=CVE-2022-28390
ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free. La función ems_usb_start_xmit en el archivo drivers/net/can/usb/ems_usb.c en el kernel de Linux versiones hasta 5.17.1, presenta una doble liberación A double-free flaw was found in the Linux kernel in the ems_usb_start_xmit function. This flaw allows an attacker to create a memory leak and corrupt the underlying data structure by calling free more than once. • https://github.com/torvalds/linux/commit/c70222752228a62135cee3409dccefd494a24646 https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6IHHC455LMSJNG4CSZ5CEAHYWY2DE5YW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LAWC35TO642FOP3UCA3C6IF7NAUFOVZ6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XFMPUI3WI4U2F7ONHRW36WDY4ZE7LGGT https://security.netapp.com/advis • CWE-415: Double Free •

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 •
