CVE-2024-26950
Estado: ModificadaAlta (7.8)—
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: wireguard: netlink: acceda al dispositivo a través de ctx en lugar de peer. el commit anterior solucionó un error que provocaba que se desreferenciara un dispositivo NULL peer->. En realidad, es más fácil y rápido en cuanto a rendimiento obtener el dispositivo desde ctx->wg. Esto también tiene más sentido semánticamente, ya que ctx->wg->peer_allowedips.seq se compara con ctx->allowedips_seq, basándose ambos en ctx. Esto también actúa como una defensa en profundidad contra los pares liberados.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
