Out-of-bounds read in Apple CoreSymbolication file parsing
CVE-2026-28918 is an out-of-bounds access vulnerability in Apple's CoreSymbolication framework. Apple states the issue was addressed with improved bounds checking. The flaw is triggered when CoreSymbolication parses a maliciously crafted file, due to insufficient validation of user-supplied data that can result in a read past the end of an allocated buffer. Apple advisories describe the impact as unexpected app termination, while supporting ZDI reporting characterizes the bug more specifically as an out-of-bounds read within CoreSymbolication.
