In the Linux kernel, the following vulnerability has been resolved:

ext4: fix memory leak in ext4 ext shift extents()

In ext4 ext shift extents(), if the extent is NULL in the while loop, the function returns immediately without releasing the path obtained via ext4 find extent(), leading to a memory leak.

Fix this by jumping to the out label to ensure the path is properly released.
