Description OSIDB Bzimport 2025-07-08 08:01:36 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: platform: exynos4-is: Add hardware sync wait to fimc_is_hw_change_mode()

In fimc_is_hw_change_mode(), the function changes camera modes without
waiting for hardware completion, risking corrupted data or system hangs
if subsequent operations proceed before the hardware is ready.

Add fimc_is_hw_wait_intmsr0_intmsd0() after mode configuration, ensuring
hardware state synchronization and stable interrupt handling.
