UBUNTU-CVE-2024-49902: High severity ubuntu/linux vulnerability

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

The listed software includes 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.

Q: What condition triggers the out-of-bounds access?

The issue occurs when the JFS dmap-tree leaf index, dmt_leafidx, is greater than the number of leaves in that dmap tree. The fix adds validation in dbFindLeaf, including for control pages as well as leaf pages.

Q: Does exploitation require authentication or user interaction?

The supplied vector indicates no privileges are required and no authentication prerequisite is shown, but user interaction is required. It also indicates network attack vector and low attack complexity.

Published Oct 21, 2024

Updated

In the Linux kernel, the following vulnerability has been resolved: jfs: check if leafidx greater than num leaves per dmap tree syzbot report a out of bounds in dbSplit, it because dmtleafidx greater than num leaves per dmap tree, add a checking for dmtleafidx in dbFindLeaf. Shaggy: Modified sanity check to apply to control pages as well as leaf pages.
