"value": "A race condition existed in the snapd 2.54.2 snap-confine binary when preparing a private mount namespace for a snap. This could allow a local attacker to gain root privileges by bind-mounting their own contents inside the snap's private mount namespace and causing snap-confine to execute arbitrary code and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1"

Esto pod\u00eda permitir a un atacante local alcanzar privilegios de root al montar su propio contenido dentro del espacio de nombres de montaje privado del snap y causar que snap-confine ejecutara c\u00f3digo arbitrario y por lo tanto obtuviera una escalada de privilegios. Corregido en snapd versiones 2.54.3+18.04, 2.54.3+20.04 y 2.54.3+21.10.1"
