If no existing connection is found and the packet\ntype is INITIAL, the function treats the packet as a new connection. It\nallocates a new channel object and inserts it into a queue where it\nwaits to be accepted by the local application with SSL_accept(3ossl).\nThe memory occupied by these initial channel objects may grow\nwithout bounds if the application is not able to call SSL_accept()\nfrequently enough to serve these inbound connection requests.\n\nThe issue is present since OpenSSL 3.5 when the QUIC server implementation\nwas added.\n\nThe fix introduces a limit for pending connections. The default limit is set\nto 256 pending connections (waiting to be accepted by the local application).\nApplications may change the default by calling SSL_set_value_uint(3ossl).\n\nFIPS impact: no\nThe FIPS module is not affected as the QUIC implementation is outside of\nthe OpenSSL FIPS module boundary.", "category":"description", "title":"Vulnerability Description" } ], "product_status":{ "fixed":[ "openEuler-24.03-LTS-SP4:openssl-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-debuginfo-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-debugsource-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-devel-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-libs-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-perl-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-3.5.6-5.oe2403sp4.src", "openEuler-24.03-LTS-SP4:openssl-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-debuginfo-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-debugsource-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-devel-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-libs-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-perl-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-help-3.5.6-5.oe2403sp4.noarch" ] }, "remediations":[ { "product_ids":[ "openEuler-24.03-LTS-SP4:openssl-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-debuginfo-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-debugsource-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-devel-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-libs-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-perl-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-3.5.6-5.oe2403sp4.src", "openEuler-24.03-LTS-SP4:openssl-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-debuginfo-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-debugsource-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-devel-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-libs-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-perl-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-help-3.5.6-5.oe2403sp4.noarch" ], "details":"openssl security update", "category":"vendor_fix", "url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3579" } ], "scores":[ { "cvss_v3":{ "baseSeverity":"HIGH", "baseScore":7.5, "vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "version":"3.1" }, "products":[ "openEuler-24.03-LTS-SP4:openssl-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-debuginfo-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-debugsource-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-devel-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-libs-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-perl-3.5.6-5.oe2403sp4.aarch64", "openEuler-24.03-LTS-SP4:openssl-3.5.6-5.oe2403sp4.src", "openEuler-24.03-LTS-SP4:openssl-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-debuginfo-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-debugsource-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-devel-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-libs-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-perl-3.5.6-5.oe2403sp4.x86_64", "openEuler-24.03-LTS-SP4:openssl-help-3.5.6-5.oe2403sp4.noarch" ] } ], "threats":[ { "details":"High", "category":"impact" } ], "title":"CVE-2026-14456" } ] }
