Title

net: macb: fix a memory corruption in extended buffer descriptor mode

Summary

In the Linux kernel, the following vulnerability has been resolved: net: macb: fix a memory corruption in extended buffer descriptor mode For quite some time we were chasing a bug which looked like a sudden permanent failure of networking and mmc on some of our devices. The bug was very sensitive to any software changes and even more to any kernel debug options. Finally we got a setup where the problem was reproducible with CONFIG_DMA_API_DEBUG=y and it revealed the issue with the rx dma: [ 16.992082] ------------[ cut here ]------------ [ 16.996779] DMA-API: macb ff0b0000.ethernet: device driver tries to free DMA memory it has not allocated [device address=0x0000000875e3e244] [size=1536 bytes] [ 17.011049] WARNING: CPU: 0 PID: 85 at kernel/dma/debug.c:1011 check_unmap+0x6a0/0x900 [ 17.018977] Modules linked in: xxxxx [ 17.038823] CPU: 0 PID: 85 Comm: irq/55-8000f000 Not tainted 5.4.0 #28 [ 17.045345] Hardware name: xxxxx [ 17.049528] pstate: 60000005 (nZCv daif -PAN -UAO) [ 17.054322] pc : check_unmap+0x6a0/0x900 [ 17.058243] lr : check_unmap+0x6a0/0x900 [ 17.062163] sp : ffffffc010003c40 [ 17.065470] x29: ffffffc010003c40 x28: 000000004000c03c [ 17.070783] x27: ffffffc010da7048 x26: ffffff8878e38800 [ 17.076095] x25: ffffff8879d22810 x24: ffffffc010003cc8 [ 17.081407] x23: 0000000000000000 x22: ffffffc010a08750 [ 17.086719] x21: ffffff8878e3c7c0 x20: ffffffc010acb000 [ 17.092032] x19: 0000000875e3e244 x18: 0000000000000010 [ 17.097343] x17: 0000000000000000 x16: 0000000000000000 [ 17.102647] x15: ffffff8879e4a988 x14: 0720072007200720 [ 17.107959] x13: 0720072007200720 x12: 0720072007200720 [ 17.113261] x11: 0720072007200720 x10: 0720072007200720 [ 17.118565] x9 : 0720072007200720 x8 : 000000000000022d [ 17.123869] x7 : 0000000000000015 x6 : 0000000000000098 [ 17.129173] x5 : 0000000000000000 x4 : 0000000000000000 [ 17.134475] x3 : 00000000ffffffff x2 : ffffffc010a1d370 [ 17.139778] x1 : b420c9d75d27bb00 x0 : 0000000000000000 [ 17.145082] Call trace: [ 17.147524] check_unmap+0x6a0/0x900 [ 17.151091] debug_dma_unmap_page+0x88/0x90 [ 17.155266] gem_rx+0x114/0x2f0 [ 17.158396] macb_poll+0x58/0x100 [ 17.161705] net_rx_action+0x118/0x400 [ 17.165445] __do_softirq+0x138/0x36c [ 17.169100] irq_exit+0x98/0xc0 [ 17.172234] __handle_domain_irq+0x64/0xc0 [ 17.176320] gic_handle_irq+0x5c/0xc0 [ 17.179974] el1_irq+0xb8/0x140 [ 17.183109] xiic_process+0x5c/0xe30 [ 17.186677] irq_thread_fn+0x28/0x90 [ 17.190244] irq_thread+0x208/0x2a0 [ 17.193724] kthread+0x130/0x140 [ 17.196945] ret_from_fork+0x10/0x20 [ 17.200510] ---[ end trace 7240980785f81d6f ]--- [ 237.021490] ------------[ cut here ]------------ [ 237.026129] DMA-API: exceeded 7 overlapping mappings of cacheline 0x0000000021d79e7b [ 237.033886] WARNING: CPU: 0 PID: 0 at kernel/dma/debug.c:499 add_dma_entry+0x214/0x240 [ 237.041802] Modules linked in: xxxxx [ 237.061637] CPU: 0 PID: 0 Comm: swapper/0 Tainted: G W 5.4.0 #28 [ 237.068941] Hardware name: xxxxx [ 237.073116] pstate: 80000085 (Nzcv daIf -PAN -UAO) [ 237.077900] pc : add_dma_entry+0x214/0x240 [ 237.081986] lr : add_dma_entry+0x214/0x240 [ 237.086072] sp : ffffffc010003c30 [ 237.089379] x29: ffffffc010003c30 x28: ffffff8878a0be00 [ 237.094683] x27: 0000000000000180 x26: ffffff8878e387c0 [ 237.099987] x25: 0000000000000002 x24: 0000000000000000 [ 237.105290] x23: 000000000000003b x22: ffffffc010a0fa00 [ 237.110594] x21: 0000000021d79e7b x20: ffffffc010abe600 [ 237.115897] x19: 00000000ffffffef x18: 0000000000000010 [ 237.121201] x17: 0000000000000000 x16: 0000000000000000 [ 237.126504] x15: ffffffc010a0fdc8 x14: 0720072007200720 [ 237.131807] x13: 0720072007200720 x12: 0720072007200720 [ 237.137111] x11: 0720072007200720 x10: 0720072007200720 [ 237.142415] x9 : 0720072007200720 x8 : 0000000000000259 [ 237.147718] x7 : 0000000000000001 x6 : 0000000000000000 [ 237.15302 ---truncated---

With `HWTSTAMP_FILTER_ALL` (TSTAMP_ALL_FRAMES) every received frame is timestamped, and even under the PTPv2 filter the MAC classifies routable unicast PTP-over-UDP (ports 319/320) at wire level without any listening socket, so a remote off-link attacker can drive the bug.\nAC:L - Within the affected configuration the hardware sets DMA_RXVALID deterministically on every timestamped descriptor, so each packet reliably produces the wrong unmap address \u2014 no race, no memory-layout dependency, infinitely repeatable. `CONFIG_MACB_USE_HWSTAMP` is `default y` and extended BD mode is enabled unconditionally on all GEM-with-TSU parts, and PTP timestamping is the headline feature of these industrial/telecom/automotive SoCs, so nothing exotic must be overcome.\nPR:N - The attacker only needs to place frames on the wire toward the device; no account, credential, or authentication of any kind exists on the path from packet arrival through the RX interrupt into `gem_rx()`. The one privileged action (SIOCSHWTSTAMP, `ns_capable(CAP_NET_ADMIN)`) is performed by the legitimate operator\u0027s PTP daemon, not by the attacker.\nUI:N - Descriptor processing happens autonomously in the NAPI softirq driven by the RX interrupt; no victim ever has to open, mount, or click anything.\nS:U - The faulty DMA bookkeeping and its consequences are confined to the kernel\u0027s own security authority; no hypervisor, guest, or sandbox boundary is crossed. Although the damage spreads to other devices\u0027 DMA (MMC), those all share the same kernel authority.\nC:H - The buffer\u0027s real mapping is never released and DMA ownership is never correctly handed back, so bounce-buffer copies run 4 bytes off (pulling adjacent bounce-pool bytes into the skb that `napi_gro_receive()` then delivers toward userspace) and an IOVA range can be freed while live and reissued to an unrelated mapping. This is maintainer-acked memory corruption leaking kernel-owned bytes into attacker-observable packet data.\nI:H - A DMA mapping left alive after the buffer is freed and reused lets the MAC write received data into memory the kernel has reassigned, and the shifted bounce copy / prematurely released IOVA modify memory outside the driver\u0027s ownership \u2014 the commit is titled \"fix a memory corruption\" and the observed blast radius reached the MMC controller\u0027s DMA.\nA:H - The reported real-world outcome is \"sudden permanent failure of networking and mmc\" on production devices \u2014 a persistent, system-wide loss of both network and storage requiring a reboot. It is additionally accompanied by DMA-API WARN splats (\"device driver tries to free DMA memory it has not allocated\", \"exceeded 7 overlapping mappings\"), which are fatal under `panic_on_warn`."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
