- jbd2: fix potential buffer head reference count leak
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
jbd2: fix potential buffer head reference count leak
As in 'jbd2fcwaitbufs' if buffer isn't uptodate, will return -EIO without update 'journal->jfcoff'. But 'jbd2fcreleasebufs' will release buffer head from ‘jfcoff - 1’ if 'bh' is NULL will terminal release which will lead to buffer head buffer head reference count leak. To solve above issue, update 'journal->jfcoff' before return -EIO.
