Google awarded $113,337 USD for a Linux vulnerability discovered by Indonesian security researcher Muhammad Alifa Ramdhan (@n0psledbyte), who works as a Principal Vulnerability Researcher at @starlabs_sg. 🤯 Ramdhan discovered a Linux Local Privilege Escalation (LPE) vulnerability involving a race condition in AF_ALG, the same subsystem later exploited in the famous Copy Fail vulnerability in 2026. He found the issue in 2025 without AI assistance and it was assigned CVE-2025-39964. His coworker, Bing-Jhong Billy Jheng, was also credited for completing the exploit chain, which enabled both privilege escalation to root and escape from a Docker container. They submitted the exploit to Google kernelCTF and received its highest reward. 💰 Ramdhan is from Tangerang, Indonesia. He graduated from Diponegoro University (@undip) in 2023 and later moved to Singapore to work full time as a vulnerability researcher. 🇮🇩 🇸🇬 idnsec.com/research/linux-lo…
