Recommended response

Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux.
Review the reported fix. Update Linux/Linux to 355b8a5d7e9a38fca8dbf7a4721450252ac7868f if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: xfs: don't leak new_bp if xfs_btree_bload_drop_buf fails LOLLM observes that in xfs_btree_bload_prep_block, xfs_btree_bload_drop_buf can hit an IO error if writing the delwri buffer list to disk fails. In this case, we fail to release new_bp, which means we lose a locked buffer. Fix that.
