{"id":"MGASA-2020-0110","summary":"Updated kernel packages fix security vulnerability","details":"This update is based on upstream 5.5.6 and fixes at least the following\nsecurity vulnerability:\n\nA flaw was found in the way KVM hypervisor handled instruction emulation\nfor the L2 guest when nested(=1) virtualization is enabled. In the\ninstruction emulation, the L2 guest could trick the L0 hypervisor into\naccessing sensitive bits of the L1 hypervisor. An L2 guest could use this\nflaw to potentially access information of the L1 hypervisor\n(CVE-2020-2732).\n\nOther additional fixes in this update:\n- a fix for broken radeon on 32bit (mga#26237)\n- broken iwlwifi for some (mga#26248)\n- a bugfix for pipe optimization backported in the 5.5.4 update\n\nFor other upstream fixes in this update, see the referenced changelogs.\n","modified":"2026-04-16T00:11:48.923072779Z","published":"2020-02-29T13:42:35Z","upstream":["CVE-2020-2732"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2020-0110.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=26258"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=26237"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=26248"},{"type":"WEB","url":"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.5.5"},{"type":"WEB","url":"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.5.6"}],"affected":[{"package":{"name":"kernel","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/kernel?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.5.6-2.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2020-0110.json"}},{"package":{"name":"kmod-virtualbox","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/kmod-virtualbox?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.18-4.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2020-0110.json"}},{"package":{"name":"kmod-xtables-addons","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/kmod-xtables-addons?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.8-4.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2020-0110.json"}}],"schema_version":"1.7.5","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
