Description OSIDB Bzimport 2024-07-29 15:20:56 UTC 
In the Linux kernel, the following vulnerability has been resolved:

misc: fastrpc: Restrict untrusted app to attach to privileged PD

Untrusted application with access to only non-secure fastrpc device
node can attach to root_pd or static PDs if it can make the respective
init request. This can cause problems as the untrusted application
can send bad requests to root_pd or static PDs. Add changes to reject
attach to privileged PDs if the request is being made using non-secure
fastrpc device node.
