Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: rapidio: rio: Fixed a possible name leak in rioregistermport. If deviceregister returns an error, the name allocated by devsetname needs to be freed. This should be done using putdevice, so that the reference in the error path is...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: Rapidio: fixed a possible UAF Use-after-Allocation when kfifoalloc fails. If kfifoalloc fails in mportcdevopen, it jumps to errfifo and simply frees priv. However, priv is still in chdev-filelist, and traversing the list may lead...
