Vulnerability from github – Published: 2025-09-23 15:31 – Updated: 2025-09-23 15:31

Details

In the Linux kernel, the following vulnerability has been resolved:

media: imx-jpeg: fix a bug of accessing array out of bounds

When error occurs in parsing jpeg, the slot isn't acquired yet, it may be the default value MXC_MAX_SLOTS. If the driver access the slot using the incorrect slot number, it will access array out of bounds. The result is the driver will change num_domains, which follows slot_data in struct mxc_jpeg_dev. Then the driver won't detach the pm domain at rmmod, which will lead to kernel panic when trying to insmod again.

Severity

7.1 (High)

Real root is not required.\nUI:N - The attacker opens the device and queues buffers themselves; no separate victim action is needed to hit the parse-error path.\nS:U - The OOB write corrupts fields in the same kernel mxc_jpeg_dev object and does not cross a VM, IOMMU, or other security-authority boundary.\nC:N - The bug is a write-only store of a fixed false/0 into the byte overlapping num_domains; there is no out-of-bounds read or other disclosure primitive.\nI:H - Accessing slot_data[MXC_MAX_SLOTS].used is an out-of-bounds write into adjacent kernel memory (num_domains). Per kernel CVSS guidance, out-of-bounds writes are scored High.\nA:H - Corrupting num_domains skips PM-domain detach on rmmod and the fix commit documents a resulting kernel panic on re-insmod; kernel crash/panic is High availability impact."
