FKIE_CVE-2017-15129
Vulnerability from fkie_nvd - Published: 2018-01-09 19:29 - Updated: 2026-06-17 01:07
Severity
Summary
A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.

Esta vulnerabilidad podr\u00eda permitir que un usuario local sin privilegios provoque una corrupci\u00f3n de memoria en el sistema, desembocando en un cierre inesperado. Debido a la naturaleza del error, no puede descartarse totalmente el escalado de privilegios, aunque se cree que es improbable."
