During rapid bond up/down cycles, rlb_deinitialize()\nfrees rx_hashtbl while RX handlers are still running, leading\nto a null pointer dereference detected by KASAN.\n\nHowever, the root cause is that rlb_arp_recv() can still be accessed\nafter setting recv_probe to NULL, which is actually a use-after-free\n(UAF) issue.

Commit\n826af7fa62e3 (\"ALSA: aloop: Fix racy access at PCM trigger\") moved\nthe peer lookup under cable-\u003elock, but the actual snd_pcm_stop() still\nruns after dropping that lock.\n\nA concurrent close can clear the capture entry from cable-\u003estreams[] and\ndetach or free its runtime while the playback trigger path still holds a\nstale peer substream pointer.\n\nKeep a per-cable count of in-flight peer stops before dropping\ncable-\u003elock, and make free_cable() wait for those stops before\ndetaching the runtime. This preserves the existing behavior while\nmaking the peer runtime lifetime explicit."

This assumption breaks for shadow paging if the guest\npage tables are modified between VM entries (similar to commit\naad885e77496, \"KVM: x86/mmu: Drop/zap existing present SPTE even\nwhen creating an MMIO SPTE\", 2026-03-27).  The flow is as follows:\n\n- a PDE is installed for a 2MB mapping, and a page in that area is\n  accessed.  KVM creates a kvm_mmu_page consisting of 512 4KB pages;\n  the kvm_mmu_page is marked by FNAME(fetch) as direct-mapped because\n  the guest\u0027s mapping is a huge page (and thus contiguous).\n\n- the PDE mapping is changed from outside the guest.\n\n- the guest accesses another page in the same 2MB area.  KVM installs\n  a new leaf SPTE and rmap entry; the SPTE uses the \"correct\" GFN\n  (i.e. based on the new mapping, as changed in the previous step) but\n  that GFN is outside of the [sp-\u003egfn, sp-\u003egfn + 511] range; therefore\n  the rmap entry cannot be found and removed when the kvm_mmu_page\n  is zapped.\n\n- the memslot that covers the first 2MB mapping is deleted, and the\n  kvm_mmu_page for the now-invalid GPA is zapped.  However, rmap_remove()\n  only looks at the [sp-\u003egfn, sp-\u003egfn + 511] range established in step 1,\n  and fails to find the rmap entry that was recorded by step 3.\n\n- any operation that causes an rmap walk for the same page accessed\n  by step 3 then walks a stale rmap and dereferences a freed kvm_mmu_page.\n  This includes dirty logging or MMU notifier invalidations (e.g., from\n  MADV_DONTNEED).\n\nThe underlying issue is that KVM\u0027s walking of shadow PTEs assumes that\nif a SPTE is present when KVM wants to install a non-leaf SPTE, then the\nexisting kvm_mmu_page must be for the correct gfn.  Because the only way\nfor the gfn to be wrong is if KVM messed up and failed to zap a SPTE...\nwhich shouldn\u0027t happen, but *actually* only happens in response to a\nguest write.\n\nThat bug dates back literally forever, as even the first version of KVM\nassumes that the GFN matches and walks into the \"wrong\" shadow page.\nHowever, that was only an imprecision until 2032a93d66fa (\"KVM: MMU:\nDon\u0027t allocate gfns page for direct mmu pages\") came along.\n\nFix it by checking for a target gfn mismatch and zapping the existing\nSPTE.  That way the old SP and rmap entries are gone, KVM installs\nthe rmap in the right location, and everyone is happy."

In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system."

Split the control handler so the frame\npath can pass an opcode that has already been pulled, and keep the\nbyte-buffer wrapper for extension control payloads.\n\nFor BNEP_SETUP_CONN_REQ, name the UUID-size byte before pulling the\nsetup payload. struct bnep_setup_conn_req carries destination and source\nservice UUIDs after that byte, each uuid_size bytes, so the parser now\ndocuments that tuple explicitly instead of leaving the pull length as an\nopaque multiplication.\n\nValidation reproduced this kernel report:\nKASAN slab-out-of-bounds in bnep_rx_frame.isra.0+0x130c/0x1790\nThe buggy address belongs to the object at ffff88800c0f7908 which belongs\nto the cache kmalloc-8 of size 8\nThe buggy address is located 0 bytes to the right of allocated 1-byte\nregion [ffff88800c0f7908, ffff88800c0f7909)\nRead of size 1\nCall trace:\n  dump_stack_lvl+0xb3/0x140 (?:?)\n  print_address_description+0x57/0x3a0 (?:?)\n  bnep_rx_frame+0x130c/0x1790 (net/bluetooth/bnep/core.c:306)\n  print_report+0xb9/0x2b0 (?:?)\n  __virt_addr_valid+0x1ba/0x3a0 (?:?)\n  srso_alias_return_thunk+0x5/0xfbef5 (?:?)\n  kasan_addr_to_slab+0x21/0x60 (?:?)\n  kasan_report+0xe0/0x110 (?:?)\n  process_one_work+0xfce/0x17e0 (kernel/workqueue.c:3200)\n  worker_thread+0x65c/0xe40 (?:?)\n  __kthread_parkme+0x184/0x230 (?:?)\n  kthread+0x35e/0x470 (?:?)\n  _raw_spin_unlock_irq+0x28/0x50 (?:?)\n  ret_from_fork+0x586/0x870 (?:?)\n  __switch_to+0x74f/0xdc0 (?:?)\n  ret_from_fork_asm+0x1a/0x30 (?:?)"

The rmap_remove()\ncall would miss entries created after the PDE change because the GFN\nof the leaf SPTE does not match the GFN of the struct kvm_mmu_page.\n\nA similar hole however remains if the modified PDE points to a non-leaf\npage.  In this case the gfn can be made to match, but the role does not\nmatch: the original large 2MB page creates a kvm_mmu_page with direct=1,\nwhile the new 4KB needs a kvm_mmu_page with direct=0.  However,\nkvm_mmu_get_child_sp() does not compare the role, and therefore reuses\nthe page.\n\nThe next step is installing a leaf (4KB) SPTE on the new path which\nrecords an rmap entry under the gfn resolved by the walk.  But when\nthat child is zapped its parent kvm_mmu_page has direct=1 and\nkvm_mmu_page_get_gfn() computes the gfn for the 4KB page as\nsp-\u003egfn + index instead of using sp-\u003eshadowed_translation[] (or sp-\u003egfns[]\nin older kernels).  It therefore fails to remove the recorded entry.\n\nWhen the memslot is dropped the shadow page is freed but the rmap\nentry survives, as in the scenario that was already fixed.  Code that\nlater walks that gfn (dirty logging, MMU notifier invalidation, and\nso on) dereferences an sptep that lies in the freed page, causing the\nuse-after-free."
