Title

media: nxp: imx8-isi: m2m: Fix streaming cleanup on release

Summary

In the Linux kernel, the following vulnerability has been resolved: media: nxp: imx8-isi: m2m: Fix streaming cleanup on release If streamon/streamoff calls are imbalanced, such as when exiting an application with Ctrl+C when streaming, the m2m usage_count will never reach zero and the ISI channel won't be freed. Besides from that, if the input line width is more than 2K, it will trigger a WARN_ON(): [ 59.222120] ------------[ cut here ]------------ [ 59.226758] WARNING: drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c:631 at mxc_isi_channel_chain+0xa4/0x120, CPU#4: v4l2-ctl/654 [ 59.238569] Modules linked in: ap1302 [ 59.242231] CPU: 4 UID: 0 PID: 654 Comm: v4l2-ctl Not tainted 6.16.0-rc4-next-20250704-06511-gff0e002d480a-dirty #258 PREEMPT [ 59.253597] Hardware name: NXP i.MX95 15X15 board (DT) [ 59.258720] pstate: 80400009 (Nzcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 59.265669] pc : mxc_isi_channel_chain+0xa4/0x120 [ 59.270358] lr : mxc_isi_channel_chain+0x44/0x120 [ 59.275047] sp : ffff8000848c3b40 [ 59.278348] x29: ffff8000848c3b40 x28: ffff0000859b4c98 x27: ffff800081939f00 [ 59.285472] x26: 000000000000000a x25: ffff0000859b4cb8 x24: 0000000000000001 [ 59.292597] x23: ffff0000816f4760 x22: ffff0000816f4258 x21: ffff000084ceb780 [ 59.299720] x20: ffff000084342ff8 x19: ffff000084340000 x18: 0000000000000000 [ 59.306845] x17: 0000000000000000 x16: 0000000000000000 x15: 0000ffffdb369e1c [ 59.313969] x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000000 [ 59.321093] x11: 0000000000000000 x10: 0000000000000000 x9 : 0000000000000000 [ 59.328217] x8 : ffff8000848c3d48 x7 : ffff800081930b30 x6 : ffff800081930b30 [ 59.335340] x5 : ffff0000859b6000 x4 : ffff80008193ae80 x3 : ffff800081022420 [ 59.342464] x2 : ffff0000852f6900 x1 : 0000000000000001 x0 : ffff000084341000 [ 59.349590] Call trace: [ 59.352025] mxc_isi_channel_chain+0xa4/0x120 (P) [ 59.356722] mxc_isi_m2m_streamon+0x160/0x20c [ 59.361072] v4l_streamon+0x24/0x30 [ 59.364556] __video_do_ioctl+0x40c/0x4a0 [ 59.368560] video_usercopy+0x2bc/0x690 [ 59.372382] video_ioctl2+0x18/0x24 [ 59.375857] v4l2_ioctl+0x40/0x60 [ 59.379168] __arm64_sys_ioctl+0xac/0x104 [ 59.383172] invoke_syscall+0x48/0x104 [ 59.386916] el0_svc_common.constprop.0+0xc0/0xe0 [ 59.391613] do_el0_svc+0x1c/0x28 [ 59.394915] el0_svc+0x34/0xf4 [ 59.397966] el0t_64_sync_handler+0xa0/0xe4 [ 59.402143] el0t_64_sync+0x198/0x19c [ 59.405801] ---[ end trace 0000000000000000 ]--- Address this issue by moving the streaming preparation and cleanup to the vb2 .prepare_streaming() and .unprepare_streaming() operations.

No network or adjacent-network path exists to this code.\nAC:L - Triggering is fully deterministic and requires no race \u2014 a single process does S_FMT, STREAMON, then close() without STREAMOFF, and the leaked usage_count/chained state plus the WARN_ON are guaranteed on the next STREAMON. The slab-reuse variant that aliases the dangling `last_ctx` is freely repeatable in a loop by the same attacker.\nPR:L - The attacker needs only an unprivileged local account with access to the video device node, which is the norm for logged-in users (video group / uaccess ACL), camera services on Android, and application accounts on embedded and automotive i.MX8/i.MX9 systems. No root or CAP_SYS_ADMIN is required anywhere along the path.\nUI:N - The attacking process performs every step itself \u2014 open, set format, streamon, close, reopen \u2014 with no victim action needed. No other user must mount, open, or interact with anything.\nS:U - The corrupted state (`m2m-\u003eusage_count`, `chained_count`, `pipe-\u003echained`, dangling `last_ctx`) and all resulting impact are confined to the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The stale `last_ctx` pointer suppresses hardware reconfiguration in `mxc_isi_m2m_device_run()`, leaving the ISI programmed with the prior context\u0027s geometry so it reads far beyond the new, smaller source buffer and copies adjacent kernel physical memory into a destination buffer the attacker mmaps and reads back. That is an attacker-steerable kernel memory disclosure primitive.\nI:H - The same stale-configuration path makes the ISI DMA engine write a full previous-geometry frame (up to 4096x2160) into a buffer allocated for a much smaller format, overwriting adjacent dma-contig/CMA kernel memory with attacker-supplied pixel data. The leaked channel/chaining state additionally leaves the hardware operating with a configuration no context owns.\nA:H - The leaked `chained_count`/`pipe-\u003echained` reliably trips `WARN_ON()` in `mxc_isi_channel_chain()`, which is a kernel panic under panic_on_warn, and the never-released channel permanently returns -EBUSY from `mxc_isi_channel_acquire()`, wedging both pipe 0 and the chained pipe so the camera capture and m2m devices are unusable until reboot."

Detection rules are retrieved from Rulezet.

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.
