Indirect branch predictor. An indirect jump instruction can choose among more than two branches. Some processors have specialized indirect branch predictors. Newer processors from Intel and AMD can predict indirect branches by using a two-level adaptive predictor.

WebAn indirect branch (also known as a computed jump, indirect jump and register-indirect jump) is a type of program control instruction present in some machine language … Web4 jan. 2024 · The indirect branch predictor of Intel CPUs only uses the lowermost 12 bits of the source instruction, thus it is easy to poison all 2^12 possible prediction histories with user-controlled memory addresses. These can then, when the indirect jump is predicted within the kernel, be speculatively executed with kernel privileges.
