UBUNTU-CVE-2023-52436: High severity ubuntu/linux-aws vulnerability

Q: Which Ubuntu kernel packages are listed as affected?

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

Q: Does exploitation require authentication or special privileges?

The supplied vector indicates network attack access, low attack complexity, no privileges required, and user interaction is required. The impact is limited to availability; confidentiality and integrity impacts are listed as none.

Q: What filesystem functionality is involved?

The issue affects f2fs extended-attribute handling when an xattr is set. The fix explicitly null-terminates the xattr list rather than relying on unused xattr space being zeroed.

Published Feb 20, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved: f2fs: explicitly null-terminate the xattr list When setting an xattr, explicitly null-terminate the xattr list. This eliminates the fragile assumption that the unused xattr space is always zeroed.
