Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: jbd2: fix data-race and null-ptr-deref
 in jbd2_journal_dirty_metadata() Since handle->h_transaction may be a NULL pointer, so we should change it
 to call is_handle_aborted(handle) first before dereferencing it. And the following data-race was reported
 in my fuzzer: ================================================================== BUG: KCSAN: data-race in
 jbd2_journal_dirty_metadata / jbd2_journal_dirty_metadata write to 0xffff888011024104 of 4 bytes by task

 missing data-race annotation for jh->b_modified. Therefore, the missing annotation needs to be added.
