Description OSIDB Bzimport 2024-10-21 21:03:03 UTC
In the Linux kernel, the following vulnerability has been resolved:

net: mvneta: Prevent out of bounds read in mvneta_config_rss()

The pp->indir[0] value comes from the user.  It is passed to:

	if (cpu_online(pp->rxq_def))

inside the mvneta_percpu_elect() function.  It needs bounds checkeding
to ensure that it is not beyond the end of the cpu bitmap.
