Description SMASH SMASH 2024-05-20 16:07:14 UTC 
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.

Comment 2 Gabriel Krisman Bertazi 2024-05-24 23:44:49 UTC 
We do not build bcachefs in our kernels. Considering this as a nop from our side. Back to security team.

All done, closing.
