SUSE CVE-2022-50428

In the Linux kernel, the following vulnerability has been resolved: ext4: fix off-by-one errors in fast-commit block filling Due to several different off-by-one errors, or perhaps due to a late change in design that wasn't fully reflected in the code that was actually merged, there are several ve...

SUSE CVE-2022-50435

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid crash when inline data creation follows DIO write When inode is created and written to using direct IO, there is nothing to clear the EXT4STATEMAYINLINEDATA flag. Thus when inode gets truncated later to say 1 byte and...

SUSE CVE-2023-53503

In the Linux kernel, the following vulnerability has been resolved: ext4: allow ext4getgroupinfo to fail Previously, ext4getgroupinfo would treat an invalid group number as BUG, since in theory it should never happen. However, if a malicious attaker or fuzzer modifies the superblock via the block...
