UBUNTU-CVE-2024-46780: High severity ubuntu/linux-aws vulnerability

Q: What access does an attacker need to exploit this issue?

The vulnerability has local attack vector, low attack complexity, and requires low privileges. No user interaction is required.

Q: What is the likely impact if exploitation succeeds?

The stated impact is high availability impact, with no confidentiality or integrity impact. The issue can lead to unsafe pointer dereferencing or memory access while sysfs methods read NILFS2 superblock data.

Q: Which Ubuntu kernel packages are listed as affected?

The listed software includes 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.

Published Sep 18, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved: nilfs2: protect references to superblock parameters exposed in sysfs The superblock buffers of nilfs2 can not only be overwritten at runtime for modifications/repairs, but they are also regularly swapped, replaced during resizing, and even abandoned when degrading to one side due to backing device issues. So, accessing them requires mutual exclusion using the reader/writer semaphore "nilfs->nssem". Some sysfs attribute show methods read this superblock buffer without the necessary mutual exclusion, which can cause problems with pointer dereferencing and memory access, so fix it.
