Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: avoid double fput on failed usercopy If the copy back to userland fails for the FASTRPCIOCTLALLOCDMABUFF ioctl, we should not assume that ‘buf-dmabuf’ is still valid. In fact, dmabuffd calls fdinstall before, there...

Astra Linux – Vulnerability in Linux

A issue was discovered in the Linux kernel through version 5.11.6. The fastrpcinternalinvoke function in drivers/misc/fastrpc.c does not prevent user applications from sending kernel RPC messages, also known as CID-20c40794eb85. This is a related issue to CVE-2019-2308...
