Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> perf/x86/amd: fix potential integer overflow on shift of a int<br /> <br /> The left shift of int 32 bit integer constant 1 is evaluated using 32 bit<br /> arithmetic and then passed as a 64 bit function argument. In the case where<br /> i is 32 or more this can lead to an overflow. Avoid this by shifting<br /> using the BIT_ULL macro instead.
