Description The issue is related to an off-by-one error in the get rpi() function within the Linux kernel's powercap module, specifically in the intel rapl component. This error can lead to an out-of-bounds access, potentially affecting the confidentiality and availability of protected information. The rp->priv->rpi array, which can be either rpi msr or rpi tpmi, has a fixed number of elements defined by NR RAPL PRIMITIVES. To prevent this off-by-one access, the comparison operator should be changed from > to >=.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
