Description
Ghidra versions through 12.1.4 contain a stack-based out-of-bounds write vulnerability in the decompiler's leftshift128 function when processing negative shift amounts from p-code. Attackers can craft malicious binaries with specific instruction sequences that trigger the overflow when decompiled, corrupting memory and potentially achieving code execution.
