CVE-2023-4206 – Use-after-free in Linux kernel's net/sched: cls_route component
https://notcve.org/view.php?id=CVE-2023-4206
A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to achieve local privilege escalation. When route4_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-free. We recommend upgrading past commit b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8. Una vulnerabilidad de use-after-free en el componente net/sched: cls_route del kernel de Linux se puede explotar para lograr una escalada de privilegios local. Cuando se llama a route4_change() en un filtro existente, toda la estructura tcf_result siempre se copia en la nueva instancia del filtro. Esto causa un problema al actualizar un filtro vinculado a una clase, ya que siempre se llama a tcf_unbind_filter() en la instancia anterior en la ruta exitosa, lo que disminuye filter_cnt de la clase a la que todavía se hace referencia y permite que se elimine, lo que lleva a un use-after-free. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8 https://kernel.dance/b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8 https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://www.debian.org/security/2023/dsa-5492 https://access.redhat.com/security/cve/CVE-2023-4206 https://bugzilla.redhat.com/show_bug.cgi?id=2225511 • CWE-416: Use After Free •
