In nested_get_vmcs12_pages(), in case of an error while processing posted interrupt address, it unmaps the 'pi_desc_page' without resetting 'pi_desc' descriptor address, which is later used in pi_test_and_clear_on(). A guest user/process could use this flaw to crash the host kernel resulting in DoS or potentially gain privileged access to a system. Kernel versions before 4.14.91 and before 4.19.13 are vulnerable.\n\n * CVE-2018-19985: The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads if_num from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds (OOB) read that potentially allows arbitrary read in the kernel address space.\n\n * CVE-2018-20784: In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rq's, which allows attackers to cause a denial of service (infinite loop in update_blocked_averages) or possibly have unspecified other impact by inducing a high load.\n\n * CVE-2019-15927: An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function build_audio_procunit in the file sound/usb/mixer.c.", "Advisory": { "From": "errata.altlinux.org", "Severity": "Critical", "Rights": "Copyright 2024 BaseALT Ltd.", "Issued": { "Date": "2019-01-16" }, "Updated": { "Date": "2019-01-16" }, "BDUs": [ { "ID": "BDU:2019-01113", "CVSS": "AV:N/AC:L/Au:N/C:P/I:P/A:P", "CVSS3": "AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "CWE": "CWE-835", "Href": "https://bdu.fstec.ru/vul/2019-01113", "Impact": "Critical", "Public": "20181230" }, { "ID": "BDU:2019-01409", "CVSS": "AV:L/AC:L/Au:N/C:C/I:N/A:N", "CVSS3": "AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", "CWE": "CWE-125", "Href": "https://bdu.fstec.ru/vul/2019-01409", "Impact": "Low", "Public": "20181212" }, { "ID": "BDU:2019-03248", "CVSS": "AV:L/AC:L/Au:S/C:C/I:C/A:C", "CVSS3": "AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H", "CWE": "CWE-416", "Href": "https://bdu.fstec.ru/vul/2019-03248", "Impact": "High", "Public": "20181218" }, { "ID": "BDU:2020-01474", "CVSS": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "CVSS3": "AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "CWE": "CWE-125", "Href": "https://bdu.fstec.ru/vul/2020-01474", "Impact": "High", "Public": "20190107" } ], "CVEs": [ { "ID": "CVE-2018-16882", "CVSS": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "CVSS3": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H", "CWE": "CWE-416", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2018-16882", "Impact": "High", "Public": "20190103" }, { "ID": "CVE-2018-19985", "CVSS": "AV:L/AC:L/Au:N/C:P/I:N/A:N", "CVSS3": "CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", "CWE": "CWE-125", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2018-19985", "Impact": "Low", "Public": "20190321" }, { "ID": "CVE-2018-20784", "CVSS": "AV:N/AC:L/Au:N/C:P/I:P/A:P", "CVSS3": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "CWE": "CWE-835", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2018-20784", "Impact": "Critical", "Public": "20190222" }, { "ID": "CVE-2019-15927", "CVSS": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "CVSS3": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "CWE": "CWE-125", "Href": "https://nvd.nist.gov/vuln/detail/CVE-2019-15927", "Impact": "High", "Public": "20190904" } ], "AffectedCPEs": { "CPEs": [ "cpe:/o:alt:spworkstation:10", "cpe:/o:alt:spserver:10" ] } } }, "Criteria": { "Operator": "AND", "Criterions": [ { "TestRef": "oval:org.altlinux.errata:tst:4001", "Comment": "ALT Linux must be installed" } ], "Criterias": [ { "Operator": "OR", "Criterions": [ { "TestRef": "oval:org.altlinux.errata:tst:20191048001", "Comment": "kernel-doc-std is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048002", "Comment": "kernel-headers-modules-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048003", "Comment": "kernel-headers-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048004", "Comment": "kernel-image-domU-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048005", "Comment": "kernel-image-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048006", "Comment": "kernel-modules-drm-ancient-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048007", "Comment": "kernel-modules-drm-nouveau-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048008", "Comment": "kernel-modules-drm-radeon-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048009", "Comment": "kernel-modules-drm-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048010", "Comment": "kernel-modules-ide-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048011", "Comment": "kernel-modules-kvm-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048012", "Comment": "kernel-modules-staging-std-def is earlier than 1:4.14.93-alt1" }, { "TestRef": "oval:org.altlinux.errata:tst:20191048013", "Comment": "kernel-modules-v4l-std-def is earlier than 1:4.14.93-alt1" } ] } ] } } ] }
