Description OSIDB Bzimport 2025-09-16 17:02:24 UTC 
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
