CVSS: 7.8EPSS: 0%CPEs: 10EXPL: 1CVE-2023-3090 – Out-of-bounds write in Linux kernel's ipvlan network driver
https://notcve.org/view.php?id=CVE-2023-3090
A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. Una vulnerabilidad de escritura fuera de los límites de la memoria en el controlador de red ipvlan del kernel de Linux se puede explotar para lograr la escalada de privilegios locales. La escritura fuera de los límites se debe a la falta de inicialización skb->cb en el controlador de red ipvlan. La vulnerabilidad es accesible si CONFIG_IPVLAN está habilitada. • http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html http://packetstormsecurity.com/files/175072/Kernel-Live-Patch-Security-Notice-LSN-0098-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=90cbed5247439a966b645b34eb0a2e037836ea8e https://kernel.dance/90cbed5247439a966b645b34eb0a2e037836ea8e https://lists.debian.org/debian-lts-announce/2023/07/msg00030.html https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://security • CWE-787: Out-of-bounds Write •
