Description
In the Linux kernel, the following vulnerability has been resolved:
media: venus: hfi: avoid null dereference in deinit
If venus_probe fails at pm_runtime_put_sync the error handling first
calls hfi_destroy and afterwards hfi_core_deinit. As hfi_destroy sets
core->ops to NULL, hfi_core_deinit cannot call the core_deinit function
anymore.
Avoid this null pointer derefence by skipping the call when necessary.
Affected configurations
• linux linux kernel (< 4.14.283)
• linux linux kernel (>= 4.15 < 4.19.247)
• linux linux kernel (>= 4.20 < 5.4.198)
• linux linux kernel (>= 5.5 < 5.10.121)
• linux linux kernel (>= 5.11 < 5.15.46)
• linux linux kernel (>= 5.16 < 5.17.14)
• linux linux kernel (>= 5.18 < 5.18.3)
