Descriptions
In the Linux kernel, the following vulnerability has been resolved:
wireguard: netlink: access device through ctx instead of peer
The previous commit fixed a bug that led to a NULL peer->device being
dereferenced. It's actually easier and faster performance-wise to
instead get the device from ctx->wg. This semantically makes more sense
too, since ctx->wg->peer_allowedips.seq is compared with
ctx->allowedips_seq, basing them both in ctx. This also acts as a
defence in depth provision against freed peers.
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.
