# CVE-2024-35948

> 8.4 HIGH

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

bcachefs: Check for journal entries overruning end of sb clean section

Fix a missing bounds check in superblock validation.

Note that we don't yet have repair code for this case - repair code for
individual items is generally low priority, since the whole superblock
is checksummed, validated prior to write, and we have backups.
