CVE-2022-50245

CVE-2022-50245 concerns a Linux kernel issue in the rapidio driver where a UAF can occur if kfifo_alloc() fails during mport_cdev_open(). The fix removes priv from the chdev->file_list before freeing it to prevent traversal from accessing a freed object (the smatch warning reference). Affected...

CVE-2022-50245 rapidio: fix possible UAF when kfifo_alloc() fails

In the Linux kernel, the following vulnerability has been resolved: rapidio: fix possible UAF when kfifoalloc fails If kfifoalloc fails in mportcdevopen, goto errfifo and just free priv. But priv is still in the chdev-filelist, then list traversal may cause UAF. This fixes the following smatch...
