NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150600_23_7-default package and not the kernel-livepatch-6_4_0-150600_23_7-default package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

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.
