Official Description

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

media: verisilicon: Fix kernel panic due to __initconst misuse

Fix a kernel panic when probing the driver as a module:

Unable to handle kernel paging request at virtual address

ffffd9c18eb05000

of_find_matching_node_and_match+0x5c/0x1a0

hantro_probe+0x2f4/0x7d0 [hantro_vpu]

The imx8mq_vpu_shared_resources array is referenced by variant

structures through their shared_devices field. When built as a

module, __initconst causes this data to be freed after module

init, but it's later accessed during probe, causing a page fault.

The imx8mq_vpu_shared_resources is referenced from non-init code,

so keeping __initconst or __initconst_or_module here is wrong.

Drop the __initconst annotation and let it live in the normal .rodata

section.

A bug of __initconst called from regular non-init probe code

leading to bugs during probe deferrals or during unbind-bind cycles.

Technical Analysis

CVE-2026-31573 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in availability disruption (denial of service), with a CVSS base score of 5.5.
