{"id":"OESA-2026-2087","summary":"musl security update","details":"musl is an implementation of the C standard library built on top of the Linux system call API, including interfaces defined in the base language standard, POSIX, and widely agreed-upon extensions. 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)","modified":"2026-08-18T01:19:56.398104392Z","published":"2026-04-25T11:11:05Z","upstream":["CVE-2026-40200","CVE-2026-6042"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2087"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40200"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6042"}],"affected":[{"package":{"name":"musl","ecosystem":"openEuler:24.03-LTS","purl":"pkg:rpm/openEuler/musl&distro=openEuler-24.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.4-6.oe2403"}]}],"ecosystem_specific":{"aarch64":["musl-debuginfo-1.2.4-6.oe2403.aarch64.rpm","musl-debugsource-1.2.4-6.oe2403.aarch64.rpm","musl-devel-1.2.4-6.oe2403.aarch64.rpm","musl-gcc-1.2.4-6.oe2403.aarch64.rpm","musl-libc-1.2.4-6.oe2403.aarch64.rpm","musl-libc-static-1.2.4-6.oe2403.aarch64.rpm"],"src":["musl-1.2.4-6.oe2403.src.rpm"],"x86_64":["musl-debuginfo-1.2.4-6.oe2403.x86_64.rpm","musl-debugsource-1.2.4-6.oe2403.x86_64.rpm","musl-devel-1.2.4-6.oe2403.x86_64.rpm","musl-gcc-1.2.4-6.oe2403.x86_64.rpm","musl-libc-1.2.4-6.oe2403.x86_64.rpm","musl-libc-static-1.2.4-6.oe2403.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-2087.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
