https://notcve.org/view.php?id=CVE-2023-39192
A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a crash or information disclosure. Se encontró una falla en el subsistema Netfilter en el kernel de Linux. El módulo xt_u32 no validó los campos en la estructura xt_u32. • https://access.redhat.com/errata/RHSA-2024:2950 https://access.redhat.com/errata/RHSA-2024:3138 https://access.redhat.com/security/cve/CVE-2023-39192 https://bugzilla.redhat.com/show_bug.cgi?id=2226784 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://www.zerodayinitiative.com/advisories/ZDI-CAN-18408 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2023-39191
An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel. Se encontró una falla de validación de entrada incorrecta en el subsistema eBPF del kernel de Linux. El problema se debe a una falta de validación adecuada de los punteros dinámicos dentro de los programas eBPF proporcionados por el usuario antes de ejecutarlos. • https://access.redhat.com/errata/RHSA-2023:6583 https://access.redhat.com/errata/RHSA-2024:0381 https://access.redhat.com/errata/RHSA-2024:0439 https://access.redhat.com/errata/RHSA-2024:0448 https://access.redhat.com/security/cve/CVE-2023-39191 https://bugzilla.redhat.com/show_bug.cgi?id=2226783 https://www.zerodayinitiative.com/advisories/ZDI-CAN-19399 • CWE-20: Improper Input Validation •

A flaw was found in the Netfilter subsystem of the Linux kernel. A race condition between IPSET_CMD_ADD and IPSET_CMD_SWAP can lead to a kernel panic due to the invocation of `__ip_set_put` on a wrong `set`. This issue may allow a local user to crash the system.

CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2023-5197 – Use-after-free in Linux kernel's netfilter: nf_tables component
https://notcve.org/view.php?id=CVE-2023-5197
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free. We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325. Una vulnerabilidad de use-after-free en el componente netfilter: nf_tables del kernel de Linux puede explotarse para lograr una escalada de privilegios local. La adición y eliminación de reglas de enlaces de cadena dentro de la misma transacción provoca que se produzca un use-after-free. Recomendamos actualizar después del compromiso f15f29fd4779be8a418b66e9d52979bb6d6c2325. • http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f15f29fd4779be8a418b66e9d52979bb6d6c2325 https://kernel.dance/f15f29fd4779be8a418b66e9d52979bb6d6c2325 https://lists.debian.org/debian-lts-announce/2024/01/msg00005.html • CWE-416: Use After Free •
