CVE-2022-50340

Summary

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:

Unexpected driver unregister! WARNING: CPU: 1 PID: 14517 at drivers/base/driver.c:270 driver_unregister+0x8f/0xb0 RIP: 0010:driver_unregister+0x8f/0xb0 Call Trace: <TASK> vimc_init+0x7d/0x1000 [vimc] do_one_initcall+0xd0/0x4e0 do_init_module+0x1cf/0x6b0 load_module+0x65c2/0x7820
