Overview
About vulnerability
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.
