In the Linux kernel, the following vulnerability has been resolved:
ext4: fix leaking uninitialized memory in fast-commit journal
When space at the end of fast-commit journal blocks is unused, make sure
to zero it out so that uninitialized memory is not leaked to disk.
A flaw was found in the Linux kernel. A local attacker could exploit an information disclosure vulnerability by not properly zeroing out unused space at the end of fast-commit journal blocks in the ext4 filesystem. This could lead to the leakage of uninitialized memory to disk, potentially allowing information disclosure.
