CVE-2022-50340

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

media: vimc: Fix wrong function called when vimc_init() fails

In vimc_init(), when platform_driver_register(&vimc_pdrv) fails, platform_driver_unregister(&vimc_pdrv) is wrongly called rather than platform_device_unregister(&vimc_pdev), which causes kernel warning:
