  - xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete KASAN reproduces a slab-use-after-free in
    __xfrm_state_delete()'s hlist_del_rcu calls under syzkaller load on linux-6.12.y stable (reproduced on     6.12.47, also reachable via the same code path on torvalds/master and on the ipsec tree). Nine unique     signatures cluster in the xfrm_state lifecycle, the load-bearing one being: BUG: KASAN: slab-use-after-     free in __hlist_del include/linux/list.h:990 [inline] BUG: KASAN: slab-use-after-free in hlist_del_rcu     include/linux/rculist.h:516 [inline] BUG: KASAN: slab-use-after-free in __xfrm_state_delete     net/xfrm/xfrm_state.c Write of size 8 at addr ffff8881198bcb70 by task kworker/u8:9/435 Workqueue: netns     cleanup_net Call Trace: __hlist_del / hlist_del_rcu __xfrm_state_delete xfrm_state_delete xfrm_state_flush     xfrm_state_fini ops_exit_list cleanup_net The other observed signatures hit the same slab object from
    __xfrm_state_lookup, xfrm_alloc_spi, __xfrm_state_insert and an OOB write variant of __xfrm_state_delete,     all on the byseq/byspi hash chains. __xfrm_state_delete() guards its byseq and byspi unhashes with value-     based predicates: if (x->km.seq) hlist_del_rcu(&x->byseq); if (x->id.spi) hlist_del_rcu(&x->byspi); while     everywhere else in the file (e.g. state_cache, state_cache_input) the safer hlist_unhashed() check is     used. xfrm_alloc_spi() sets x->id.spi = newspi inside xfrm_state_lock and then immediately inserts into     byspi, but a path that observes x->id.spi != 0 outside of xfrm_state_lock can still skip-or-hit the byspi     unhash inconsistently with whether x is actually on the list. The same holds for x->km.seq versus byseq,     and the bydst/bysrc unhashes have no predicate at all, so a second __xfrm_state_delete() on the same     object writes through LIST_POISON pprev. The defensive change here: - Use hlist_del_init_rcu() instead of     hlist_del_rcu() on bydst, bysrc, byseq and byspi so a second deletion is a no-op rather than a write     through LIST_POISON pprev. The byseq/byspi nodes are already initialised in xfrm_state_alloc(). - Test     hlist_unhashed() rather than the value predicate for byseq/byspi, so the unhash decision tracks list state     rather than mutable scalar fields. Empirical verification: applied this patch on top of v6.12.47, rebuilt,     and re-ran the same syzkaller harness for 1h16m on a previously-crashy configuration that produced ~100     hits each of slab-use-after-free Read in xfrm_alloc_spi / Read in __xfrm_state_lookup / Write in
    __xfrm_state_delete. After the patch, 7.1M execs across 32 VMs at ~1550 exec/sec produced zero xfrm_state     UAF/OOB hits. /proc/slabinfo confirms the xfrm_state slab is actively allocated and freed during the run     (~143 KiB resident), so the fuzzer is still exercising those code paths -- they just no longer crash.
    Reproduction: - Linux 6.12.47 x86_64 + KASAN_GENERIC + KASAN_INLINE + KCOV - syzkaller @     746545b8b1e4c3a128db8652b340d3df90ce61db - 32 QEMU/KVM VMs x 2 vCPU on AWS c5.metal bare metal - 9 unique     signatures collected in ~9h, all within xfrm_state lifecycle (CVE-2026-46116)

Note that Nessus relies on the presence of the package as reported by the vendor.
