"value": "AV:L - The vulnerability is reached only through the local mount(2)/fsconfig(2)+fsmount(2) filesystem-mount path on an erofs image plus its `device=` parameters; there is no network-facing consumer of this code.\nAC:L - The trigger is fully deterministic \u2014 an erofs image whose on-disk device table count matches the supplied `device=` options, with one such path naming a regular file instead of a block device, reliably yields -ENOTBLK and the use-after-free write on every attempt. Heap reuse of the freed `erofs_sb_info` is attacker-assisted because the free\u2192write window spans an attacker-influenceable `filp_open()` path walk that can be stalled arbitrarily, and the spray runs from the attacker\u0027s own threads.\nPR:N - The attacker needs no account or capability on the target: they only supply the malicious erofs image and/or arrange the `device=` path (which is resolved with symlink following at fill_super time, in directories such as container blob/staging dirs) to be a non-block file, while a privileged mounter \u2014 automounter, container/composefs runtime, or mount helper handling multi-device erofs images \u2014 performs the mount. This matches the kernel CNA treatment of crafted-image mount bugs (e.g. CVE-2025-38204, CVE-2025-38230, CVE-2025-38652).\nUI:R - The flaw only fires when someone mounts the attacker-supplied erofs image with the corresponding `device=` parameters; it cannot be triggered without that mount action.\nS:U - The freed object, the corrupted slab memory, and the resulting crash or escalation are all inside the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `file_inode(sbi-\u003edif0.file)-\u003ei_mode` is read back out of the freed `erofs_sb_info`; if a sprayed object has taken the slot the kernel dereferences an attacker-groomed pointer and reads memory at an attacker-chosen location, and use-after-free of a kmalloc object is generally leverageable into kernel-memory disclosure.\nI:H - `sbi-\u003edif0.file = file` writes a valid kernel `struct file *` at a fixed offset (16) into a freed generic-kmalloc chunk, clobbering whatever live object has been reallocated there \u2014 a classic UAF write primitive that overwrites pointers/state of an unrelated kernel object and is a strong stepping stone to control-flow hijacking.\nA:H - Even without grooming, the UAF read of poisoned/reused memory and the follow-on `get_tree_nodev()` path (which calls `erofs_fc_fill_super()` with `s_fs_info == NULL`, immediately writing through a NULL `sbi`) produce a kernel oops/panic, and the path also leaks a `struct file` reference on every attempt."

Although the same helpers are also reached from the server-side listen path, the freeing side of the race is not remotely controllable, so local access is the realistic delivery vector.\nAC:L - The attacker controls both sides of the race: they create the netdev and route in their own network namespace, initiate the SMC connect that caches the dst, and delete the device concurrently; the reader blocks on rtnl_lock held by the deleting task and dereferences the device immediately after netdev_run_todo() frees it, making the window wide and the trigger reliably repeatable in a loop.\nPR:L - No capability check exists on AF_SMC socket creation and the module autoloads via net-pf-43 for unprivileged users; the netdev create/delete side needs only CAP_NET_ADMIN inside a user+network namespace obtainable with unshare -Urn by any unprivileged local user.\nUI:N - The attacker performs every step \u2014 socket creation, local SMC listener, connect, and device deletion \u2014 with no action required from any other user or administrator.\nS:U - The use-after-free corrupts kernel memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed net_device is read and its adj_list is walked, yielding an attacker-influenceable pointer that is further dereferenced (dev.parent, dev_port, dev_net()-\u003enet_generic()); with a page-level heap spray of the freed kvmalloc allocation this provides an arbitrary-read oriented primitive over kernel memory.\nI:H - Controlling the freed net_device contents lets the attacker steer base_ndev to a crafted address that is then used for mutex_lock(\u0026pnettable-\u003elock) and list traversal, giving a controlled write/corruption primitive suitable for privilege escalation.\nA:H - The use-after-free reliably produces a KASAN-detected invalid access and, on production kernels, wild-pointer dereferences leading to kernel oops or panic, and it can be re-triggered at will."

Per CNA guidance Bluetooth-reachable code is Adjacent, and an attacker-controlled LE Audio device can drive the CIS/BIS setup and teardown events that complete the race.\nAC:L - The attacker controls both sides of the race directly \u2014 one thread calls `listen()` (which drops the socket lock across `iso_listen_bis()`, leaving `sk_state == BT_BOUND` while `conn-\u003esk` is set) while another calls `close()`, hitting the `default:` arm of `__iso_sock_close()` that zaps the socket without clearing `conn-\u003esk`. The window can be retried indefinitely, and the delayed conn put gives a long, tunable reallocation window.\nPR:L - `iso_sock_create()` performs no capability check, so any unprivileged local user can open a `BTPROTO_ISO` `SOCK_SEQPACKET` socket and drive the listen/close race; no CAP_NET_ADMIN or root is required.\nUI:N - The race is driven entirely by the attacker\u0027s own threads plus asynchronous HCI events; no action by a legitimate user or administrator is needed.\nS:U - The corruption is confined to kernel slab memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - A use-after-free on a freed `struct iso_pinfo` lets the attacker reoccupy the slab slot with a chosen object, and the stale `conn-\u003esk` plus the `iso_sock_hold()` read of freed memory can be leveraged into kernel memory disclosure.\nI:H - `iso_conn_free()` performs an 8-byte write at a fixed offset into the freed socket object; after heap spraying this becomes a targeted write into an attacker-chosen kernel structure, enabling pointer/refcount corruption and control-flow hijack.\nA:H - The use-after-free reliably corrupts slab memory and causes kernel oops/panic (as demonstrated by the KASAN slab-use-after-free report in the sibling SCO fix), and it can be triggered repeatedly."

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usb-audio: Fix potential overflow of PCM transfer buffer\n\nThe PCM stream data in USB-audio driver is transferred over USB URB\npacket buffers, and each packet size is determined dynamically. The\npacket sizes are limited by some factors such as wMaxPacketSize USB\ndescriptor. OTOH, in the current code, the actually used packet sizes\nare determined only by the rate and the PPS, which may be bigger than\nthe size limit above. This results in a buffer overflow, as reported\nby syzbot.\n\nBasically when the limit is smaller than the calculated packet size,\nit implies that something is wrong, most likely a weird USB\ndescriptor. So the best option would be just to return an error at\nthe parameter setup time before doing any further operations.\n\nThis patch introduces such a sanity check, and returns -EINVAL when\nthe packet size is greater than maxpacksize. The comparison with\nep-\u003epacksize[1] alone should suffice since it\u0027s always equal or\ngreater than ep-\u003epacksize[0]."

Although a malformed descriptor is one way to reach it, no physical interaction is required for a local attacker on a machine with an attached USB audio device.\nAC:L - The attacker deterministically chooses the rate and sample format that make `packsize[1] * stride` exceed the `wMaxPacketSize`-derived buffer, then triggers the copy by starting playback \u2014 no race, no memory-layout guessing, and the condition is fully reproducible on every URB submission.\nPR:L - Only access to the ALSA PCM device node is required, which is granted to the logged-in session user via logind ACLs or membership in the `audio` group; no CAP_SYS_ADMIN or root is needed.\nUI:N - The attacking process performs open/hw_params/prepare/write entirely on its own; no victim action is needed, and on desktop/Android systems PipeWire/AudioFlinger will even drive the stream automatically on hotplug.\nS:U - The corruption stays within the kernel\u0027s own memory and the USB host controller\u0027s DMA-coherent pool, managed by the same security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - The oversized `iso_frame_desc` lengths cause the host controller to DMA kernel memory beyond the allocated coherent buffer out to the USB device, disclosing adjacent kernel heap contents to the attacker; heap corruption can also be leveraged for broader arbitrary read.\nI:H - `copy_to_urb()` memcpy\u0027s an attacker-controlled length of attacker-controlled PCM bytes past the end of the coherent URB buffer, giving a heap out-of-bounds write with controlled content \u2014 a primitive suitable for corrupting adjacent objects and hijacking control flow.\nA:H - Overrunning the DMA-coherent transfer buffer corrupts neighbouring kernel/DMA-pool memory and reliably produces an oops or panic, as observed in the syzbot report and the related bugzilla crash reports."

H2C_DATA PDU for uninitialized command slot \u2192 both pointers NULL\n\nThe fix validates both cmd-\u003ereq.sg and cmd-\u003eiov before calling\nnvmet_tcp_build_pdu_iovec(). Both checks are required because:\n- Uninitialized commands: both NULL\n- READ commands: cmd-\u003ereq.sg allocated, cmd-\u003eiov NULL\n- WRITE commands: both allocated"

"value": "AV:N - The vulnerable code is in the NVMe over TCP target receive path and is reachable by sending NVMe/TCP PDUs to the target TCP listener. A remote peer can send ICREQ followed by malformed H2C_DATA over the network.\nAC:L - No race or hard-to-control state is required for the pre-CONNECT trigger; the attacker only needs to send a valid IC handshake and then an H2C_DATA PDU with coherent length fields. The required packet sequence is deterministic.\nPR:N - The simplest trigger occurs after ICREQ/ICRESP but before CONNECT, before host NQN allow-list checks, controller creation, or DH-HMAC-CHAP authentication are reached. Thus an unauthenticated network peer can reach the vulnerable handler on a non-TLS or plaintext-accepted target port.\nUI:N - Exploitation does not require any victim user action after the target service is listening. The attacker sends protocol messages directly to the NVMe/TCP target.\nS:U - The impact is within the vulnerable kernel/target system\u2019s own security authority. There is no VM escape, IOMMU bypass, or cross-authority boundary change.\nC:N - The bug is a NULL pointer dereference of uninitialized command buffers, not an out-of-bounds read or use-after-free. The investigated paths support a crash impact, not disclosure of kernel memory.\nI:N - The dereferences are to NULL command buffer pointers and do not provide a practical arbitrary write or control-flow primitive. The fix and related history characterize the issue as invalid state leading to NULL dereference.\nA:H - The vulnerable dereference occurs in kernel context and can produce an oops or panic in the nvmet-tcp workqueue path. Repeated unauthenticated network triggers can deny availability of the target system or service."
