Description
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.
