[PATCH 0/2] net: isolate SKB data area allocations

From: Pedro Falcato <pfalcato@suse.de>
Date: 2026-06-02 18:31:42
Also in: linux-hardening, linux-mm, lkml

This is a rather simple series that attempts to address a possible
exploitation avenue - the allocation of skbs around the network stack, which
frequently get user-controlled contents. Found while doing some amateur
exploitation analysis for some other issue, elsewhere.

Patch 0 is a precursor patch that adds a slab allocation helper, patch 1
does the actual bucketing.
I don't know what tree should pick this up, so I just based this on linux-next.

Pedro Falcato (2):
  mm/slab: add a node-track-caller variant for kmem buckets allocation
  net: skb: isolate skb data area allocations into a separate bucket
