CVE-2026-43218 Details
Description
In the Linux kernel, the following vulnerability has been resolved: media: i2c/tw9903: Fix potential memory leak in tw9903_probe() In one of the error paths in tw9903_probe(), the memory allocated in v4l2_ctrl_handler_init() and v4l2_ctrl_new_std() is not freed. Fix that by calling v4l2_ctrl_handler_free() on the handler in that error path.
A memory leak vulnerability has been identified in the Linux kernel's TW9903 video decoder I2C driver. The issue arises in the 'tw9903_probe()' function, where memory allocated for the V4L2 control handler is not properly released in certain error scenarios. This oversight can lead to increased memory usage over time.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability. The patch is included in the official Linux kernel repository.
