CVE-2022-49748

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...

CVE-2022-49748

CVE-2022-49748 relates to the Linux kernel: perf/x86/amd shift of a 32-bit int constant 1 is computed in 32‑bit arithmetic and then passed as a 64‑bit argument, which can overflow when i ≥ 32. The fix uses the BIT_ULL macro for the shift to avoid overflow. Several connected advisories (Astra Linu...
