{"id":"AZL-113411","summary":"CVE-2026-97037 affecting package gcc 13.2.0-7","details":"Building a malicious package that uses cgo could cause arbitrary code execution at link time by passing linker script files to the host linker via \"#cgo LDFLAGS\". Split \"-Wl,\" flags that consume a following argument (such as \"-Wl,-rpath\", \"-Wl,--just-symbols\", and \"-Wl,-undefined\") previously accepted a bare second argument without a \"-Wl,\" prefix, which the compiler driver passes directly to the linker as a positional input file. Additionally, when using GNU ld.bfd, flags such as \"-framework\", \"-Wl,-framework\", \"-Wl,-undefined\", \"-Wl,--just-symbols\", \"-Wl,-R\", \"-Wl,-subsystem\", and (on non-Darwin platforms) \"-Wl,-sectcreate\" could cause ld.bfd to interpret their arguments as linker scripts if they named a regular file on disk. The go command now requires a \"-Wl,\" prefix on the second token of split \"-Wl,\" flags (except \"-Wl,-R\"), verifies that these flags do not reference linker script files, and disallows bare \"-Wl,--warn-backrefs-exclude\".","modified":"2026-11-13T14:17:22.561951371Z","published":"2026-11-11T05:19:57Z","upstream":["CVE-2026-97037"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97037"}],"affected":[{"package":{"name":"gcc","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/gcc"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"13.2.0-7"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-113411.json"}}],"schema_version":"1.9.2"}
