"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mscc: ocelot: fix incorrect IFH SRC_PORT field in ocelot_ifh_set_basic()\n\nPackets injected by the CPU should have a SRC_PORT field equal to the\nCPU port module index in the Analyzer block (ocelot->num_phys_ports).\n\nThe blamed commit copied the ocelot_ifh_set_basic() call incorrectly\nfrom ocelot_xmit_common() in net/dsa/tag_ocelot.c. Instead of calling\nwith \"x\", it calls with BIT_ULL(x), but the field is not a port mask,\nbut rather a single port index.\n\n[ side note: this is the technical debt of code duplication :( ]\n\nThe error used to be silent and doesn't appear to have other\nuser-visible manifestations, but with new changes in the packing\nlibrary, it now fails loudly as follows:\n\n------------[ cut here ]------------\nCannot store 0x40 inside bits 46-43 - will truncate\nsja1105 spi2.0: xmit timed out\nWARNING: CPU: 1 PID: 102 at lib/packing.c:98 __pack+0x90/0x198\nsja1105 spi2.0: timed out polling for tstamp\nCPU: 1 UID: 0 PID: 102 Comm: felix_xmit\nTainted: G W N 6.13.0-rc1-00372-gf706b85d972d-dirty #2605\nCall trace:\n __pack+0x90/0x198 (P)\n __pack+0x90/0x198 (L)\n packing+0x78/0x98\n ocelot_ifh_set_basic+0x260/0x368\n ocelot_port_inject_frame+0xa8/0x250\n felix_port_deferred_xmit+0x14c/0x258\n kthread_worker_fn+0x134/0x350\n kthread+0x114/0x138\n\nThe code path pertains to the ocelot switchdev driver and to the felix\nsecondary DSA tag protocol, ocelot-8021q. Here seen with ocelot-8021q.\n\nThe messenger (packing) is not really to blame, so fix the original\ncommit instead."

"value": "AV:N - The vulnerable code is the transmit/injection path of an Ethernet switch driver, reached whenever the kernel emits a frame on an ocelot/felix port — including replies to unauthenticated remote traffic (ARP/ICMP/TCP) and routed traffic, and specifically the ocelot-8021q PTP response path shown in the reported stack trace, where a remote PTP peer's Delay_Req elicits the injection.\nAC:L - The defect is unconditional and deterministic — every CPU-injected frame on affected hardware passes the out-of-range value to the packing helper, requiring no race, no memory grooming, and no state the attacker cannot induce.\nPR:N - No credentials or privileges are required; an unauthenticated remote peer that causes the device to transmit a single frame out an ocelot port (PTP exchange, ARP, ping, forwarded traffic) reaches the code, and locally the path is the ordinary ndo_start_xmit with no capability check.\nUI:N - No victim action is needed — normal packet transmission, which the attacker can induce remotely, is sufficient to reach the faulty field encoding.\nS:U - The fault and its consequences stay within the kernel's own security authority on the affected host; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The injection frame header is a fixed 16-byte stack buffer written at compile-time-constant bit offsets, and the packing helper rejects/masks the oversized value, so no out-of-bounds read occurs and no kernel data is disclosed.\nI:N - No memory is corrupted and no attacker-controlled data is modified; the only altered state is a switch metadata field that was already zero before the offending commit, so there is no exploitable write or data-integrity loss.\nA:H - Each injected frame hits an unconditional WARN() (not WARN_ONCE) in the packing library, producing a stack dump per transmitted packet — this taints the kernel, floods the log and cripples throughput on embedded switch platforms, and panics outright on systems configured with panic_on_warn, all repeatable at will by a remote peer."
