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 •
