Google Addresses Critical Android Vulnerability CVE-2025-27363 in May 2025 Security Update

Google has released its May 2025 Android Security Update, addressing a critical vulnerability identified as CVE-2025-27363. This flaw, which has been actively exploited in the wild, affects the System component of Android devices and could lead to remote code execution without requiring additional execution privileges.

Understanding CVE-2025-27363

The vulnerability stems from an out-of-bounds write issue in the FreeType open-source font rendering library, specifically in versions 2.13.0 and earlier. When parsing TrueType GX and variable font files, the flawed code assigns a signed short value to an unsigned long, causing a buffer overflow. This allows attackers to write up to six signed long integers out of bounds, potentially leading to arbitrary code execution. Vulert+1Tenable®+1
