Description

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

Affected configurations

• linux linux kernel (>= 5.4.22 < 5.4.231) • linux linux kernel (>= 5.5.6 < 5.10.166) • linux linux kernel (>= 5.11 < 5.15.91) • linux linux kernel (>= 5.16 < 6.1.9) • linux linux kernel 6.2
