  3. CVE-2022-49527
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: venus: hfi: evitar la desreferencia nula en deinit Si venus_probe falla en pm_runtime_put_sync, la gestión de errores primero llama a hfi_destroy y luego a hfi_core_deinit. Como hfi_destroy establece core->ops en NULL, hfi_core_deinit ya no puede llamar a la función core_deinit. Evite esta desreferencia de puntero nulo omitiendo la llamada cuando sea necesario.
