Title
jbd2: fix potential use-after-free in jbd2_fc_wait_bufs
Summary
In the Linux kernel, the following vulnerability has been resolved: jbd2: fix potential use-after-free in jbd2_fc_wait_bufs In 'jbd2_fc_wait_bufs' use 'bh' after put buffer head reference count which may lead to use-after-free. So judge buffer if uptodate before put buffer head reference count.
Severity
