Bug ID: 216871
Summary: use after free when journal read failed
Product: File System
Version: 2.5
Kernel Version: 6.0
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ReiserFS
Assignee: reiserfs-devel@vger.kernel.org
Reporter: 1527030098@qq.com
Regression: No
When reading the journal header block failed, journal_read return 1. But the
caller journal_init ignores the value and doesn't handle this case. It will
cause a UAF bug at fs unmount.
