CVE-2022-49527: media: venus: hfi: avoid null dereference in deinit
Published Feb 26, 2025
·Updated
In the Linux kernel, the following vulnerability has been resolved:
media: venus: hfi: avoid null dereference in deinit
If venusprobe fails at pmruntimeputsync the error handling first calls hfidestroy and afterwards hficoredeinit. As hfidestroy sets core->ops to NULL, hficoredeinit cannot call the coredeinit function anymore.
Avoid this null pointer derefence by skipping the call when necessary.
