Descriptions

In the Linux kernel, the following vulnerability has been resolved: net: fix removing a namespace with conflicting altnames Mark reports a BUG() when a net namespace is removed. kernel BUG at net/core/dev.c:11520! Physical interfaces moved outside of init_net get "refunded"
to init_net when that namespace disappears. The main interface
name may get overwritten in the process if it would have
conflicted. We need to also discard all conflicting altnames.
Recent fixes addressed ensuring that altnames get moved
with the main interface, which surfaced this problem.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net: corrige la eliminación de un espacio de nombres con nombres alternativos en conflicto. Mark informa un ERROR() cuando se elimina un espacio de nombres de red. ¡ERROR del kernel en net/core/dev.c:11520! Las interfaces físicas movidas fuera de init_net se "reembolsan" a init_net cuando ese espacio de nombres desaparece. El nombre de la interfaz principal puede sobrescribirse en el proceso si hubiera entrado en conflicto. También debemos descartar todos los nombres alternativos en conflicto. Las correcciones recientes abordaron garantizar que los nombres alternativos se movieran con la interfaz principal, lo que provocó este problema.
