Description
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.
