macOS, File Parsing Vulnerability, CVE-2025-24106 (Critical)

CVE-2025-24106 is a critical vulnerability affecting macOS systems, specifically in file parsing mechanisms. The flaw arises due to improper validation of file structures during parsing, which can lead to unexpected application termination or potentially arbitrary code execution. When a maliciously crafted file is processed by the affected macOS versions, the system fails to handle the file correctly, causing a crash or allowing an attacker to exploit memory corruption. This vulnerability impacts macOS Ventura 13.7.3, macOS Sequoia 15.3, and macOS Sonoma 14.7.3. Apple addressed the issue by implementing improved checks in file parsing routines to prevent such crashes and potential exploitation.
