CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 0CVE-2023-3390 – Use-after-free in Linux kernel's netfilter subsystem
https://notcve.org/view.php?id=CVE-2023-3390
A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97. Se encontró una vulnerabilidad de use-after-free en el subsistema netfilter del kernel de Linux en net/netfilter/nf_tables_api.c. El manejo de errores mal manejado con NFT_MSG_NEWRULE permite usar un puntero colgante en la misma transacción que causa una vulnerabilidad de use-after-free. Esta falla permite que un atacante local con acceso de usuario cause un problema de escalada de privilegios. • http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=1240eb93f0616b21c675416516ff3d74798fdc97 https://kernel.dance/1240eb93f0616b21c675416516ff3d74798fdc97 https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://security.netapp.com/advisory/ntap-20230818-0004 https://www.debian.org/security/2023/dsa-5448 https&# • CWE-416: Use After Free •
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 •
