- Summary
- rapidio: fix possible UAF when kfifo_alloc() fails
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
rapidio: fix possible UAF when kfifo_alloc() fails
If kfifoalloc() fails in mportcdevopen(), goto errfifo and just free priv. But priv is still in the chdev->file_list, then list traversal may cause UAF. This fixes the following smatch warning:
drivers/rapidio/devices/riomportcdev.c:1930 mportcdevopen() warn: '&priv->list' not removed from list
