It is lightweight, fast, simple, free, and strives to be correct in the sense of standards conformance and safety.\r\n\r\nSecurity Fix(es):\n\nAn issue was discovered in musl libc 0.7.10 through 1.2.6. Stack-based memory corruption can occur during qsort of very large arrays, due to incorrectly implemented double-word primitives. The number of elements must exceed about seven million, i.e., the 32nd Leonardo number on 32-bit platforms (or the 64th Leonardo number on 64-bit platforms, which is not practical).(CVE-2026-40200)\n\nA security flaw has been discovered in musl libc up to 1.2.6. Affected is the function iconv of the file src/locale/iconv.c of the component GB18030 4-byte Decoder. Performing a manipulation results in inefficient algorithmic complexity. The attack must be initiated from a local position. To fix this issue, it is recommended to deploy a patch.(CVE-2026-6042)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"musl","purl":"pkg:rpm/openEuler/musl&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.4-6.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["musl-debuginfo-1.2.4-6.oe2403sp3.aarch64.rpm","musl-debugsource-1.2.4-6.oe2403sp3.aarch64.rpm","musl-devel-1.2.4-6.oe2403sp3.aarch64.rpm","musl-gcc-1.2.4-6.oe2403sp3.aarch64.rpm","musl-libc-1.2.4-6.oe2403sp3.aarch64.rpm","musl-libc-static-1.2.4-6.oe2403sp3.aarch64.rpm"],"src":["musl-1.2.4-6.oe2403sp3.src.rpm"],"x86_64":["musl-debuginfo-1.2.4-6.oe2403sp3.x86_64.rpm","musl-debugsource-1.2.4-6.oe2403sp3.x86_64.rpm","musl-devel-1.2.4-6.oe2403sp3.x86_64.rpm","musl-gcc-1.2.4-6.oe2403sp3.x86_64.rpm","musl-libc-1.2.4-6.oe2403sp3.x86_64.rpm","musl-libc-static-1.2.4-6.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1928"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40200"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6042"}],"database_specific":{"severity":"High"}}
