UBUNTU-CVE-2024-53155: Medium severity ubuntu/linux vulnerability

Q: What conditions are required to trigger this issue?

An attacker needs local access with low privileges. The reported path involves io_uring reads reaching OCFS2 file read handling, where a kiocb structure may have an uninitialized private field.

Q: Which Ubuntu kernel packages are identified as affected?

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

Q: What is the expected impact?

The issue is an uninitialized-value condition in OCFS2 read handling. The supplied vector rates availability impact as low and indicates no confidentiality or integrity impact.

Q: What change resolves the underlying problem?

The fix introduces ocfs2_iocb_init_rw_locked() and uses it in OCFS2 read and write iteration paths where ocfs2_dio_end_io() may handle the I/O control block.

Frequently Asked Questions

What conditions are required to trigger this issue?

An attacker needs local access with low privileges. The reported path involves io_uring reads reaching OCFS2 file read handling, where a kiocb structure may have an uninitialized private field.

Which Ubuntu kernel packages are identified as affected?

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

What is the expected impact?

The issue is an uninitialized-value condition in OCFS2 read handling. The supplied vector rates availability impact as low and indicates no confidentiality or integrity impact.

What change resolves the underlying problem?

The fix introduces ocfs2_iocb_init_rw_locked() and uses it in OCFS2 read and write iteration paths where ocfs2_dio_end_io() may handle the I/O control block.
