Description OSIDB Bzimport 2026-05-27 15:04:36 UTC
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.
