CVE-2026-31573

Medium

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.
