CVE-2026-58106 Incomplete fix for CVE-2025-40843: safe_strcpy is called with PATH_MAX into fullPath+2, writing 2 bytes past the buffer on every CodeChecker log invocation

CVE-2025-40843 https://github.com/advisories/GHSA-5xf2-f6ch-6p8r was fixed by replacing unchecked strcpy with a bounded safestrcpy helper. At ldlogger-tool-gcc.c:129 the destination passed to that helper is fullPath + 2, but the size passed down is the full PATHMAX. safestrcpy is strncpy, which...

CVE-2026-58106

CodeChecker through 6.28.2 contains an incomplete fix for CVE-2025-40843. In ldlogger-tool-gcc.c:129 , the bounded helper safe_strcpy() is called with the full PATH_MAX size, but the destination is fullPath + 2 , leaving only 4094 bytes. Because safe_strcpy() is a strncpy() that NUL-pads to the f...
