Description

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.

Affected configurations

• linux linux kernel (>= 5.6 < 5.10.215) • linux linux kernel (>= 5.11 < 5.15.154) • linux linux kernel (>= 5.16 < 6.1.84) • linux linux kernel (>= 6.2 < 6.6.24) • linux linux kernel (>= 6.7 < 6.7.12) • linux linux kernel (>= 6.8 < 6.8.3) • debian debian linux 10.0
