The number of memory-related vulnerabilities in Android has significantly decreased over the past five years, attributed to Google’s use of memory-safe languages like Rust. Memory safety issues now only account for 24% of all Android vulnerabilities, down from 76% in 2019. This shift has been credited to Google’s secure-by-design approach and gradual transition to memory-safe languages.
Summary of Meeting Notes:
– The number of memory-related vulnerabilities in Android has significantly decreased over the past 5 years, with only 24% of vulnerabilities being memory safety issues compared to 76% in 2019. The total number of memory-related vulnerabilities is projected to be 36 for 2024, a substantial decrease from 223 in 2019.
– Google’s approach, “Safe Coding,” prioritizes memory-safe languages like Rust for new code development, contributing to the reduction in memory-related vulnerabilities.
– Memory safety vulnerabilities, particularly buffer overflows and use-after-free bugs, have historically accounted for over 60% of all application software vulnerabilities and have been disproportionately severe. The use of memory-safe languages like Rust, Go, and C# helps address these issues by providing automatic memory management and built-in safety checks.
– Google has gradually transitioned to using memory-safe languages like Rust for new Android features, while leaving existing code largely untouched except for bug fixes. The company’s goal is to gradually increase the use of memory-safe languages over time, rather than immediately converting all existing C and C++ code to Rust.
– The decrease in memory-related bugs is not only due to the growing use of memory-safe languages but also because older vulnerabilities have decayed with time. Additionally, new code has been the primary source of vulnerabilities, emphasizing the need for a fundamental change in code development processes.
