{"id":"DEBIAN-CVE-2026-13573","details":"A vulnerability was found in llvm llvm-project up to 22.1.6. This affects the function llvm::StringMap::insert in the library /lib/IR/ValueSymbolTable.cpp of the component ValueSymbolTable Module. The manipulation results in stack-based buffer overflow. Attacking locally is a requirement. The exploit has been made public and could be used. The presence of this vulnerability remains uncertain at this time. The LLVM project explains, that the reported behavior is outside its documented security scope and therefore not considered a security vulnerability.","modified":"2026-09-12T10:00:15.074695718Z","published":"2026-06-29T15:16:38.687Z","upstream":["CVE-2026-13573"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-13573"}],"affected":[{"package":{"name":"llvm-toolchain-18","ecosystem":"Debian:13","purl":"pkg:deb/debian/llvm-toolchain-18?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:18.1.8-18","1:18.1.8-20"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13573.json"}},{"package":{"name":"llvm-toolchain-19","ecosystem":"Debian:12","purl":"pkg:deb/debian/llvm-toolchain-19?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:19.1.0-1","1:19.1.0-2","1:19.1.0-3","1:19.1.0-3.1","1:19.1.0-4","1:19.1.0~++20240724103243+7af27be6633a-1~exp1","1:19.1.0~++rc2-1~exp1","1:19.1.0~++rc3-1","1:19.1.0~++rc3-1~exp1","1:19.1.0~++rc3-2","1:19.1.0~++rc4-1","1:19.1.0~++rc4-2","1:19.1.0~++rc4-3","1:19.1.0~++rc4-4","1:19.1.0~++rc4-5","1:19.1.1-1","1:19.1.1-1+powerpc","1:19.1.2-1","1:19.1.2-1+hurd.1","1:19.1.2-1+hurd.2","1:19.1.2-1+powerpc","1:19.1.2-1+powerpc.1","1:19.1.2-2","1:19.1.3-1","1:19.1.3-2","1:19.1.4-1","1:19.1.4-1~deb12u1","1:19.1.5-1","1:19.1.6-1","1:19.1.7-1","1:19.1.7-10","1:19.1.7-10.1","1:19.1.7-11","1:19.1.7-12","1:19.1.7-13","1:19.1.7-14","1:19.1.7-15","1:19.1.7-16","1:19.1.7-17","1:19.1.7-18","1:19.1.7-19","1:19.1.7-2","1:19.1.7-20","1:19.1.7-22","1:19.1.7-3","1:19.1.7-3+hurd.1","1:19.1.7-3~deb11u1","1:19.1.7-3~deb12u1","1:19.1.7-6","1:19.1.7-6+powerpc","1:19.1.7-7","1:19.1.7-7+hurd.1","1:19.1.7-8","1:19.1.7-9"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13573.json"}},{"package":{"name":"llvm-toolchain-19","ecosystem":"Debian:13","purl":"pkg:deb/debian/llvm-toolchain-19?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:19.1.7-10","1:19.1.7-10.1","1:19.1.7-11","1:19.1.7-12","1:19.1.7-13","1:19.1.7-14","1:19.1.7-15","1:19.1.7-16","1:19.1.7-17","1:19.1.7-18","1:19.1.7-19","1:19.1.7-20","1:19.1.7-22","1:19.1.7-3","1:19.1.7-3+hurd.1","1:19.1.7-6","1:19.1.7-6+powerpc","1:19.1.7-7","1:19.1.7-7+hurd.1","1:19.1.7-8","1:19.1.7-9"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13573.json"}},{"package":{"name":"llvm-toolchain-19","ecosystem":"Debian:14","purl":"pkg:deb/debian/llvm-toolchain-19?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:19.1.7-10","1:19.1.7-10.1","1:19.1.7-11","1:19.1.7-12","1:19.1.7-13","1:19.1.7-14","1:19.1.7-15","1:19.1.7-16","1:19.1.7-17","1:19.1.7-18","1:19.1.7-19","1:19.1.7-20","1:19.1.7-22","1:19.1.7-3","1:19.1.7-3+hurd.1","1:19.1.7-6","1:19.1.7-6+powerpc","1:19.1.7-7","1:19.1.7-7+hurd.1","1:19.1.7-8","1:19.1.7-9"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13573.json"}},{"package":{"name":"llvm-toolchain-21","ecosystem":"Debian:14","purl":"pkg:deb/debian/llvm-toolchain-21?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:21.1.0-1","1:21.1.0~+rc2-1~exp1","1:21.1.1-1","1:21.1.2-1","1:21.1.2-2","1:21.1.2-3","1:21.1.2-4","1:21.1.3-1","1:21.1.4-1","1:21.1.4-2","1:21.1.4-3","1:21.1.4-4","1:21.1.4-5","1:21.1.4-6","1:21.1.4-7","1:21.1.4-8","1:21.1.5-1","1:21.1.5-1+hurd.1","1:21.1.6-1","1:21.1.6-2","1:21.1.6-3","1:21.1.7-1","1:21.1.8-1","1:21.1.8-10","1:21.1.8-2","1:21.1.8-3","1:21.1.8-3~bpo13+1","1:21.1.8-3~bpo13+2","1:21.1.8-4","1:21.1.8-5","1:21.1.8-6","1:21.1.8-7","1:21.1.8-8","1:21.1.8-9"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13573.json"}},{"package":{"name":"llvm-toolchain-22","ecosystem":"Debian:12","purl":"pkg:deb/debian/llvm-toolchain-22?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:22.1.0-1","1:22.1.0-2","1:22.1.0~+rc1-1~exp1","1:22.1.0~+rc2-1~exp1","1:22.1.0~+rc3-1~exp1","1:22.1.1-1","1:22.1.2-1","1:22.1.3-1","1:22.1.4-1","1:22.1.5-1","1:22.1.6-1","1:22.1.7-1","1:22.1.7-1+hurd.1","1:22.1.8-1","1:22.1.8-1~deb11u1","1:22.1.8-1~deb12u1","1:22.1.8-1~deb13u1","1:22.1.8-1~deb13u2","1:22.1.8-1~deb13u3","1:22.1.8-1~deb13u4"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13573.json"}},{"package":{"name":"llvm-toolchain-22","ecosystem":"Debian:13","purl":"pkg:deb/debian/llvm-toolc
