UBUNTU-CVE-2024-50116: High severity ubuntu/linux vulnerability

Q: What conditions are needed to trigger the kernel bug?

The issue is triggered when nilfs2 reads a corrupted filesystem image and degrades to read-only. The resulting uncleared buffer delay flag can cause the BUG_ON check in submit_bh_wbc() to fail.

Q: Is normal nilfs2 write activity affected?

No. The described state inconsistency does not occur when the buffer is written normally by nilfs2 log writing.

Q: Which Ubuntu kernel package families are listed as affected?

The listed packages are ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, and ubuntu/linux-gcp-fips.

Updated

In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix kernel bug due to missing clearing of buffer delay flag Syzbot reported that after nilfs2 reads a corrupted file system image and degrades to read-only, the BUGON check for the buffer delay flag in submitbhwbc() may fail, causing a kernel bug. This is because the buffer delay flag is not cleared when clearing the buffer state flags to discard a page/folio or a buffer head. So, fix this. This became necessary when the use of nilfs2's own page clear routine was expanded. This state inconsistency does not occur if the buffer is written normally by log writing.

Frequently Asked Questions

What conditions are needed to trigger the kernel bug?

The issue is triggered when nilfs2 reads a corrupted filesystem image and degrades to read-only. The resulting uncleared buffer delay flag can cause the BUG_ON check in submit_bh_wbc() to fail.

Is normal nilfs2 write activity affected?

No. The described state inconsistency does not occur when the buffer is written normally by nilfs2 log writing.

Which Ubuntu kernel package families are listed as affected?

The listed packages are ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-aws, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, and ubuntu/linux-gcp-fips.
