Details

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 ?

7.8 (High)
