{"id":"MGASA-2019-0414","summary":"Updated kernel packages fix security vulnerabilities","details":"This update is based on upstream 5.4.6 and fixes various potential\nsecurity issues related to buffer overflows, double frees, NUll  pointer\ndereferences, improper / missing input validations and so on. It also\nadds other bugfixes all over the kernel.\n\nOther fixes added in this update:\n- x86/MCE/AMD: Do not use rdmsr_safe_on_cpu() in smca_configure(),\n  fixing an deadlock issue.\n- x86/mm: Split vmalloc_sync_all(), fixing up big performance\n  regressions in some x86_64 workloads \n  (example: reaim.jobs_per_min -79.7% regression) \n- The Intel cpu/gpu specific security fixes in upstream 5.3.11 broke\n  RC6 and that prevents CPUs from entering C-states, causing higher\n  power consumption. This update adds upstream fixes to restore\n  RC6 to a working state (fdo#112315)\n- radeon changes in upstream 5.4 to remove the 'need_dma32 flag' has\n  been reverted as it caused radeon to malfunction on 32bit kernels\n- iwlwifi fixes for firmware crashes (mga#25926), failures on warm\n  reboot, and performance fixes\n\nWireGuard has been updated to 0.0.20191219.\n\nFor other fixes in this update, see the referenced changelogs.\n","modified":"2026-04-16T04:26:08.993893Z","published":"2019-12-25T22:57:53Z","references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2019-0414.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=25897"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=25926"},{"type":"WEB","url":"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.3"},{"type":"WEB","url":"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.4"},{"type":"WEB","url":"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.5"},{"type":"WEB","url":"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.6"}],"affected":[{"package":{"name":"kernel","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/kernel?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.4.6-2.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2019-0414.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":"6.0.14-16.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2019-0414.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":"3.7-6.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2019-0414.json"}},{"package":{"name":"wireguard-tools","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/wireguard-tools?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.0.20191219-1.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2019-0414.json"}}],"schema_version":"1.7.5","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
