I think this is still present on Ubuntu 26.04 (Resolute) with kernel 7.0.0-15-generic.
Same symptoms: skbuff_small_head (~21 GB) + skbuff_head_cache (~8 GB) growing in unreclaimable slab until OOM killer fires. Trigger: DDEV Docker stack (Traefik + web + MySQL + Redis). The audit log shows repeated AppArmor denials for fusermount3, and kauditd_printk_skb: 12 callbacks suppressed appears just before each OOM event, consistent with the audit skb leak described here. Stopping the Docker containers drops SUnreclaim from ~28 GB back to ~450 MB immediately.
