          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvhost-scsi: Fix handling of multiple calls to vhost_scsi_set_endpoint\n\nIf vhost_scsi_set_endpoint is called multiple times without a\nvhost_scsi_clear_endpoint between them, we can hit multiple bugs\nfound by Haoran Zhang:\n\n1. Use-after-free when no tpgs are found:\n\nThis fixes a use after free that occurs when vhost_scsi_set_endpoint is\ncalled more than once and calls after the first call do not find any\ntpgs to add to the vs_tpg. When vhost_scsi_set_endpoint first finds\ntpgs to add to the vs_tpg array match=true, so we will do:\n\nvhost_vq_set_backend(vq, vs_tpg);\n...\n\nkfree(vs-\u003evs_tpg);\nvs-\u003evs_tpg = vs_tpg;\n\nIf vhost_scsi_set_endpoint is called again and no tpgs are found\nmatch=false so we skip the vhost_vq_set_backend call leaving the\npointer to the vs_tpg we then free via:\n\nkfree(vs-\u003evs_tpg);\nvs-\u003evs_tpg = vs_tpg;\n\nIf a scsi request is then sent we do:\n\nvhost_scsi_handle_vq -\u003e vhost_scsi_get_req -\u003e vhost_vq_get_backend\n\nwhich sees the vs_tpg we just did a kfree on.\n\n2. Tpg dir removal hang:\n\nThis patch fixes an issue where we cannot remove a LIO/target layer\ntpg (and structs above it like the target) dir due to the refcount\ndropping to -1.\n\nThe problem is that if vhost_scsi_set_endpoint detects a tpg is already\nin the vs-\u003evs_tpg array or if the tpg has been removed so\ntarget_depend_item fails, the undepend goto handler will do\ntarget_undepend_item on all tpgs in the vs_tpg array dropping their\nrefcount to 0. At this time vs_tpg contains both the tpgs we have added\nin the current vhost_scsi_set_endpoint call as well as tpgs we added in\nprevious calls which are also in vs-\u003evs_tpg.\n\nLater, when vhost_scsi_clear_endpoint runs it will do\ntarget_undepend_item on all the tpgs in the vs-\u003evs_tpg which will drop\ntheir refcount to -1. Userspace will then not be able to remove the tpg\nand will hang when it tries to do rmdir on the tpg dir.\n\n3. Tpg leak:\n\nThis fixes a bug where we can leak tpgs and cause them to be\nun-removable because the target name is overwritten when\nvhost_scsi_set_endpoint is called multiple times but with different\ntarget names.\n\nThe bug occurs if a user has called VHOST_SCSI_SET_ENDPOINT and setup\na vhost-scsi device to target/tpg mapping, then calls\nVHOST_SCSI_SET_ENDPOINT again with a new target name that has tpgs we\nhaven\u0027t seen before (target1 has tpg1 but target2 has tpg2). When this\nhappens we don\u0027t teardown the old target tpg mapping and just overwrite\nthe target name and the vs-\u003evs_tpg array. Later when we do\nvhost_scsi_clear_endpoint, we are passed in either target1 or target2\u0027s\nname and we will only match that target\u0027s tpgs when we loop over the\nvs-\u003evs_tpg. We will then return from the function without doing\ntarget_undepend_item on the tpgs.\n\nBecause of all these bugs, it looks like being able to call\nvhost_scsi_set_endpoint multiple times was never supported. The major\nuser, QEMU, already has checks to prevent this use case. So to fix the\nissues, this patch prevents vhost_scsi_set_endpoint from being called\nif it\u0027s already successfully added tpgs. To add, remove or change the\ntpg config or target name, you must do a vhost_scsi_clear_endpoint\nfirst."

There is no network-facing path \u2014 a guest can index the freed array but cannot itself perform the ioctl that frees it.\nAC:L - Triggering is fully deterministic and race-free: one successful `SET_ENDPOINT` followed by a second `SET_ENDPOINT` with a wwpn matching no tpg unconditionally frees the array still installed as the vq backend. Heap-spraying the freed 2048-byte kmalloc-2k object is standard and entirely under the attacker\u0027s control.\nPR:L - Neither `vhost_scsi_open()`, `vhost_scsi_ioctl()`, nor the vhost core performs any `capable()`/`CAP_*` check \u2014 only an open fd on `/dev/vhost-scsi` is needed, which the unprivileged QEMU/libvirt-qemu process routinely holds in any host actually using vhost-scsi. A compromised or malicious deprivileged VMM process reaches the bug with a single additional ioctl, so no real root is required.\nUI:N - The attacker performs both ioctls and the subsequent virtqueue kick entirely on its own; no action by any other user or administrator is needed. The LIO tpg configuration is pre-existing baseline state in any vhost-scsi deployment, not a victim action.\nS:U - The dangling backend and corrupted heap are host kernel memory, and the attacker is already a host-local process, so the compromise stays within the kernel\u0027s own security authority. This is standard local kernel privilege escalation rather than a VM-escape or IOMMU boundary crossing.\nC:H - `vhost_scsi_get_req()` performs `READ_ONCE(vs_tpg[*vc-\u003etarget])` on the freed array with an attacker-chosen index, then downstream code dereferences the resulting pointer, giving a use-after-free read that can be steered into arbitrary kernel memory disclosure. Per UAF guidance the attacker controls the contents of the reclaimed slab object, enabling arbitrary read.\nI:H - Reclaiming the freed kmalloc-2k object yields a fully attacker-controlled `struct vhost_scsi_tpg *` that is dereferenced and whose `tpg_nexus-\u003etvn_se_sess` is passed into `target_init_cmd()`/`target_submit_tmr()`, a classic fake-object path to arbitrary write and control-flow hijack. The configfs `config_item` refcount underflow to \u22121 additionally corrupts target-core object lifetime state.\nA:H - The dangling backend reliably produces a kernel oops/panic on the next SCSI request even without successful exploitation. The refcount underflow also permanently wedges the LIO tpg so `rmdir` on the tpg/target directory hangs and the objects can never be removed short of reboot."

          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nx86/mm/pat: Fix VM_PAT handling when fork() fails in copy_page_range()\n\nIf track_pfn_copy() fails, we already added the dst VMA to the maple\ntree. As fork() fails, we\u0027ll cleanup the maple tree, and stumble over\nthe dst VMA for which we neither performed any reservation nor copied\nany page tables.\n\nConsequently untrack_pfn() will see VM_PAT and try obtaining the\nPAT information from the page table -- which fails because the page\ntable was not copied.\n\nThe easiest fix would be to simply clear the VM_PAT flag of the dst VMA\nif track_pfn_copy() fails. However, the whole thing is about \"simply\"\nclearing the VM_PAT flag is shaky as well: if we passed track_pfn_copy()\nand performed a reservation, but copying the page tables fails, we\u0027ll\nsimply clear the VM_PAT flag, not properly undoing the reservation ...\nwhich is also wrong.\n\nSo let\u0027s fix it properly: set the VM_PAT flag only if the reservation\nsucceeded (leaving it clear initially), and undo the reservation if\nanything goes wrong while copying the page tables: clearing the VM_PAT\nflag after undoing the reservation.\n\nNote that any copied page table entries will get zapped when the VMA will\nget removed later, after copy_page_range() succeeded; as VM_PAT is not set\nthen, we won\u0027t try cleaning VM_PAT up once more and untrack_pfn() will be\nhappy. Note that leaving these page tables in place without a reservation\nis not a problem, as we are aborting fork(); this process will never run.\n\nA reproducer can trigger this usually at the first try:\n\n  https://gitlab.com/davidhildenbrand/scratchspace/-/raw/main/reproducers/pat_fork.c\n\n  WARNING: CPU: 26 PID: 11650 at arch/x86/mm/pat/memtype.c:983 get_pat_info+0xf6/0x110\n  Modules linked in: ...\n  CPU: 26 UID: 0 PID: 11650 Comm: repro3 Not tainted 6.12.0-rc5+ #92\n  Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-2.fc40 04/01/2014\n  RIP: 0010:get_pat_info+0xf6/0x110\n  ...\n  Call Trace:\n   \u003cTASK\u003e\n   ...\n   untrack_pfn+0x52/0x110\n   unmap_single_vma+0xa6/0xe0\n   unmap_vmas+0x105/0x1f0\n   exit_mmap+0xf6/0x460\n   __mmput+0x4b/0x120\n   copy_process+0x1bf6/0x2aa0\n   kernel_clone+0xab/0x440\n   __do_sys_clone+0x66/0x90\n   do_syscall_64+0x95/0x180\n\nLikely this case was missed in:\n\n  d155df53f310 (\"x86/mm/pat: clear VM_PAT if copy_p4d_range failed\")\n\n... and instead of undoing the reservation we simply cleared the VM_PAT flag.\n\nKeep the documentation of these functions in include/linux/pgtable.h,\none place is more than sufficient -- we should clean that up for the other\nfunctions like track_pfn_remap/untrack_pfn separately."

Then, rtnl_unlock() by Thread B will release RTNL\nand wait for netdev_put() by Thread A.\n\nThread A, however, must hold RTNL after the unlock in dev_ifsioc(),\nwhich may take long under RTNL pressure, resulting in the splat by\nThread B.\n\n  Thread A (SIOCBRDELIF)           Thread B (SIOCBRDELBR)\n  ----------------------           ----------------------\n  sock_ioctl                       sock_ioctl\n  `- sock_do_ioctl                 `- br_ioctl_call\n     `- dev_ioctl                     `- br_ioctl_stub\n        |- rtnl_lock                     |\n        |- dev_ifsioc                    \u0027\n        \u0027  |- dev = __dev_get_by_name(...)\n           |- netdev_hold(dev, ...)      .\n       /   |- rtnl_unlock  ------.       |\n       |   |- br_ioctl_call       `---\u003e  |- rtnl_lock\n  Race |   |  `- br_ioctl_stub           |- br_del_bridge\n  Window   |     |                       |  |- dev = __dev_get_by_name(...)\n       |   |     |  May take long        |  `- br_dev_delete(dev, ...)\n       |   |     |  under RTNL pressure  |     `- unregister_netdevice_queue(dev, ...)\n       |   |     |               |       `- rtnl_unlock\n       \\   |     |- rtnl_lock  \u003c-\u0027          `- netdev_run_todo\n           |     |- ...                        `- netdev_run_todo\n           |     `- rtnl_unlock                   |- __rtnl_unlock\n           |                                      |- netdev_wait_allrefs_any\n           |- netdev_put(dev, ...)  \u003c----------------\u0027\n                                                Wait refcnt decrement\n                                                and log splat below\n\nTo avoid blocking SIOCBRDELBR unnecessarily, let\u0027s not call\ndev_ioctl() for SIOCBRADDIF and SIOCBRDELIF.\n\nIn the dev_ioctl() path, we do the following:\n\n  1. Copy struct ifreq by get_user_ifreq in sock_do_ioctl()\n  2. Check CAP_NET_ADMIN in dev_ioctl()\n  3. Call dev_load() in dev_ioctl()\n  4. Fetch the master dev from ifr.ifr_name in dev_ifsioc()\n\n3. can be done by request_module() in br_ioctl_call(), so we move\n1., 2., and 4. to br_ioctl_stub().\n\nNote that 2. is also checked later in add_del_if(), but it\u0027s better\nperformed before RTNL.\n\nSIOCBRADDIF and SIOCBRDELIF have been processed in dev_ioctl() since\nthe pre-git era, and there seems to be no specific reason to process\nthem there.\n\n[0]:\nunregister_netdevice: waiting for wpan3 to become free.

No network protocol handler is involved, and physical access is not strictly required since loop and network-block-backed images work equally well.\nAC:L - The attacker fully controls every byte of the on-disk image, including the ea_inode feature bit, the inode\u0027s i_extra_isize, the xattr magic, the entry array, and which inode sits last in its inode-table block so the walk runs off the end of the buffer_head page allocation. The corruption is deterministic at mount during orphan cleanup with no race to win and no dependency on kernel memory layout the attacker cannot influence.\nPR:N - The attacker needs no account or privilege on the target system \u2014 they only supply the malicious filesystem image, which is then mounted by root, by an automount daemon such as udisks2, or by a container/VM image-handling service acting on the attacker\u0027s data. All privileged operations along the path are performed by the victim system on the attacker\u0027s behalf.\nUI:N - On the common desktop, kiosk, and appliance configurations where udisks2/systemd automounts removable media, plugging in the device triggers the mount with no human participation, and the bug fires immediately during ext4_orphan_cleanup() inside ext4_fill_super() rather than requiring any subsequent file access. Container and VM image-mount services likewise mount attacker-supplied images unattended.\nS:U - The out-of-bounds read and write occur in kernel heap memory within the same kernel security authority that hosts the vulnerable ext4 code. There is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The loop performs an unbounded (pre-mitigation) or several-byte-past-the-allocation (post-mitigation) out-of-bounds read of adjacent kernel heap memory past the inode-table buffer_head, and those leaked bytes are consumed as e_value_inum/e_hash/e_value_size values that steer subsequent inode lookups and quota accounting, making adjacent kernel memory contents observable through filesystem state and error output.\nI:H - `entry-\u003ee_value_inum = 0; entry-\u003ee_value_size = 0;` writes 8 zero bytes through an out-of-bounds entry pointer into adjacent kernel heap memory, and the OOB-derived inode numbers drive ext4_xattr_inode_dec_ref()/ext4_orphan_add() to decrement refcounts and orphan arbitrary inodes. This combination of controlled kernel heap zeroing plus arbitrary on-disk metadata corruption is a usable memory-corruption primitive, not a bounded misread.\nA:H - KASAN reproduces the issue as a use-after-free/out-of-bounds access past a page-sized buffer_head allocation during mount; on a production kernel the same access corrupts adjacent slab memory and the bogus inode ref-count decrements trigger EXT4-fs errors and oops/panic. The crash occurs during ext4_fill_super() and can be repeated on every mount attempt."

No local access is needed at any point.\nAC:L - The attacker drives both sides of the race by pipelining concurrent SMB2 requests on one connection (ksmbd\u0027s workqueue has no per-connection serialization), and the race window spans a blocking userspace IPC round-trip of up to 2 seconds, while the target handle ID is a predictable small `ida_alloc()` value.\nPR:L - Reaching create_smb2_pipe() requires a completed SMB2 SESSION_SETUP and a TREE_CONNECT to IPC$, i.e. any valid low-privileged SMB account (or a guest account where mapping is enabled). This matches the scoring of the sibling ksmbd session UAFs CVE-2025-22040/CVE-2025-22041.\nUI:N - The attacker generates every request in the sequence; no action by a legitimate user or administrator is required to trigger the race.\nS:U - The corruption is confined to the kernel\u0027s own heap and the ksmbd server\u0027s data structures, all within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The success path returns `entry-\u003eid` read from freed slab memory and sends it back to the attacker as the CREATE response VolatileFileId, directly leaking reclaimed kernel heap contents, and the UAF/double-free of a small generic-cache object gives a spray-controlled read primitive.\nI:H - The error path double-frees the entry and calls ksmbd_rpc_id_free() on a stale IDA id now owned by a different live RPC handle, yielding freelist corruption and cross-handle aliasing that are classic stepping stones to arbitrary write and control-flow hijack in kernel context.\nA:H - Use-after-free and double-free of a kmalloc object reliably produce slab corruption, oops, or panic, and the attacker can repeat the race indefinitely over new sessions to crash the server."

No remote peer data reaches the vulnerable code.\nAC:L - The attacker controls both sides of the race, looping RDMA_NLDEV_CMD_NEWLINK in one thread and RDMA_NLDEV_CMD_SET (rename) in another; `enable_device_and_get()` marks the device DEVICE_REGISTERED and drops to refcount 2 before the unprotected `kobject_uevent()`, leaving a reliably hittable window that syzkaller reproduced.\nPR:L - The gate is `netlink_capable(skb, CAP_NET_ADMIN)`, which checks init_user_ns and so is not obtainable via `unshare -Urn`, but CAP_NET_ADMIN in the initial user namespace is routinely delegated to non-root, container-confined workloads (Docker/K8s do not enable user namespaces by default, and RDMA/SR-IOV network plugins commonly run with `--cap-add=NET_ADMIN`). Scored as a low-privileged principal rather than real host root.\nUI:N - The attacker triggers both the device registration and the concurrent rename entirely on its own via netlink; no victim action is involved.\nS:U - The use-after-free is in kernel slab memory and its impact stays within the kernel\u0027s security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The freed `kobj-\u003ename` slab object is `strlen`\u0027d and `memcpy`\u0027d into the `DEVPATH=` uevent variable that is broadcast to userspace listeners and the uevent helper, so reallocated kernel heap contents are disclosed outside the kernel, and the unterminated `strlen` reads out of bounds past the freed chunk.\nI:H - This is a slab use-after-free where the attacker can spray the freed kmalloc chunk and control the data the kernel then consumes; per UAF-class scoring the reallocation primitive is treated as exploitable for kernel state corruption, and the resulting bogus DEVPATH also drives userspace device management onto the wrong sysfs path.\nA:H - KASAN reports a slab-use-after-free read that can fault and oops when the backing page is freed or under KFENCE/page poisoning, and `kobject_get_path()`\u0027s `retry` loop can spin under a sustained rename storm, both causing denial of service."

When multiple threads or VFs try to access the same\nregisters simultaneously, it can lead to race conditions. By using the\nRLCG interface, the driver can serialize access to the registers. This\nmeans that only one thread can access the registers at a time,\npreventing conflicts and ensuring that operations are performed\ncorrectly. Additionally, when a low-priority task holds a mutex that a\nhigh-priority task needs, ie., If a thread holding a spinlock tries to\nacquire a mutex, it can lead to priority inversion. register access in\namdgpu_virt_rlcg_reg_rw especially in a fast code path is critical.\n\nThe call stack shows that the function amdgpu_virt_rlcg_reg_rw is being\ncalled, which attempts to acquire the mutex. This function is invoked\nfrom amdgpu_sriov_wreg, which in turn is called from\ngmc_v11_0_flush_gpu_tlb.\n\nThe [ BUG: Invalid wait context ] indicates that a thread is trying to\nacquire a mutex while it is in a context that does not allow it to sleep\n(like holding a spinlock).\n\nFixes the below:\n\n[  253.013423] =============================\n[  253.013434] [ BUG: Invalid wait context ]\n[  253.013446] 6.12.0-amdstaging-drm-next-lol-050225 #14 Tainted: G     U     OE\n[  253.013464] -----------------------------\n[  253.013475] kworker/0:1/10 is trying to lock:\n[  253.013487] ffff9f30542e3cf8 (\u0026adev-\u003evirt.rlcg_reg_lock){+.+.}-{3:3}, at: amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu]\n[  253.013815] other info that might help us debug this:\n[  253.013827] context-{4:4}\n[  253.013835] 3 locks held by kworker/0:1/10:\n[  253.013847]  #0: ffff9f3040050f58 ((wq_completion)events){+.+.}-{0:0}, at: process_one_work+0x3f5/0x680\n[  253.013877]  #1: ffffb789c008be40 ((work_completion)(\u0026wfc.work)){+.+.}-{0:0}, at: process_one_work+0x1d6/0x680\n[  253.013905]  #2: ffff9f3054281838 (\u0026adev-\u003egmc.invalidate_lock){+.+.}-{2:2}, at: gmc_v11_0_flush_gpu_tlb+0x198/0x4f0 [amdgpu]\n[  253.014154] stack backtrace:\n[  253.014164] CPU: 0 UID: 0 PID: 10 Comm: kworker/0:1 Tainted: G     U     OE      6.12.0-amdstaging-drm-next-lol-050225 #14\n[  253.014189] Tainted: [U]=USER, [O]=OOT_MODULE, [E]=UNSIGNED_MODULE\n[  253.014203] Hardware name: Microsoft Corporation Virtual Machine/Virtual Machine, BIOS Hyper-V UEFI Release v4.1 11/18/2024\n[  253.014224] Workqueue: events work_for_cpu_fn\n[  253.014241] Call Trace:\n[  253.014250]  \u003cTASK\u003e\n[  253.014260]  dump_stack_lvl+0x9b/0xf0\n[  253.014275]  dump_stack+0x10/0x20\n[  253.014287]  __lock_acquire+0xa47/0x2810\n[  253.014303]  ? srso_alias_return_thunk+0x5/0xfbef5\n[  253.014321]  lock_acquire+0xd1/0x300\n[  253.014333]  ? amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu]\n[  253.014562]  ? __lock_acquire+0xa6b/0x2810\n[  253.014578]  __mutex_lock+0x85/0xe20\n[  253.014591]  ? amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu]\n[  253.014782]  ? sched_clock_noinstr+0x9/0x10\n[  253.014795]  ? srso_alias_return_thunk+0x5/0xfbef5\n[  253.014808]  ? local_clock_noinstr+0xe/0xc0\n[  253.014822]  ? amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu]\n[  253.015012]  ? srso_alias_return_thunk+0x5/0xfbef5\n[  253.015029]  mutex_lock_nested+0x1b/0x30\n[  253.015044]  ? mutex_lock_nested+0x1b/0x30\n[  253.015057]  amdgpu_virt_rlcg_reg_rw+0xf6/0x330 [amdgpu]\n[  253.015249]  amdgpu_sriov_wreg+0xc5/0xd0 [amdgpu]\n[  253.015435]  gmc_v11_0_flush_gpu_tlb+0x44b/0x4f0 [amdgpu]\n[  253.015667]  gfx_v11_0_hw_init+0x499/0x29c0 [amdgpu]\n[  253.015901]  ? __pfx_smu_v13_0_update_pcie_parameters+0x10/0x10 [amdgpu]\n[  253.016159]  ? srso_alias_return_thunk+0x5/0xfbef5\n[  253.016173]  ? smu_hw_init+0x18d/0x300 [amdgpu]\n[  253.016403]  amdgpu_device_init+0x29ad/0x36a0 [amdgpu]\n[  253.016614]  amdgpu_driver_load_kms+0x1a/0xc0 [amdgpu]\n[  253.0170\n---truncated---"

              "value": "AV:L - Triggering requires local operations \u2014 creating/tearing down a page_pool-backed netdev (veth NAPI/GRO toggle, XDP detach, `ip link set down`, channel/ring reconfiguration) while freeing socket-queued skbs via close/purge syscalls. A remote peer can supply the packets that populate the pool but cannot initiate `page_pool_destroy()`, so the attack vector is local.\nAC:L - The attacker controls both sides of the race: they create the page pool, park page_pool-backed skbs on their own socket receive queue, then concurrently destroy the pool and purge the queue from another thread. Per-attempt the window is short, but it is entirely attacker-created and repeatable indefinitely (the `page_pool_release_retry` worker re-opens it every DEFER_TIME), with no condition outside the attacker\u0027s influence.\nPR:L - The producer side (`skb_release_data` \u2192 `napi_pp_put_page` \u2192 `page_pool_recycle_in_ring`) needs no privileges at all \u2014 just an ordinary socket. The destroy side needs only CAP_NET_ADMIN inside a network namespace, which any unprivileged user obtains with `unshare -Urn` to create a veth pair and toggle its NAPI/XDP state; no real root in the init namespace is required.\nUI:N - The attacking process performs the pool teardown and the skb free itself from its own threads. No victim action or cooperating process is needed.\nS:U - The freed object and the corruption both live in the host kernel\u0027s own memory; no VM, hypervisor, or IOMMU boundary is crossed.\nC:H - This is a use-after-free on a `kzalloc_node()`-allocated `struct page_pool`, which an attacker can groom and replace with a controlled slab object; the stale `pool-\u003erecycle_stats` dereference then reads attacker-influenced kernel memory, and the lockdep `lock_release` path reads the freed `dep_map`, yielding a kernel-memory disclosure primitive.\nI:H - The racing producer writes into freed memory unconditionally \u2014 `r-\u003equeue[r-\u003eproducer++]` stores a netmem pointer, `r-\u003eproducer` is incremented, and `spin_unlock_bh()` performs a store-release to the freed lock word at a fixed offset in a reallocated object. With `CONFIG_PAGE_POOL_STATS`, `recycle_stat_inc(pool, ring)` additionally increments through a pointer read out of the reallocated object, giving a near-arbitrary write usable for control-flow hijack.\nA:H - The confirmed syzbot outcome is a KASAN slab-use-after-free splat (an oops, and a panic under `panic_on_warn`/`panic_on_oops`); unpoisoned, the stray writes corrupt the slab and the recycled page ends up double-owned, readily producing kernel panics and network-stack breakage."
