multiple vulnerabilities as referenced in the SUSE-SU-2021:2416-1 advisory.\n\n - An issue was discovered in the Linux kernel before 5.10. drivers/infiniband/core/ucma.c has a use-after- free because the ctx is reached via the ctx_list in some ucma_migrate_id situations where ucma_close is called, aka CID-f5449e74802c. (CVE-2020-36385)\n\n - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.\n This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space (CVE-2021-22555)\n\n - fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user, aka CID-8cae8cd89f05. (CVE-2021-33909)\n\n - To fix this vulnerability, update the affected packages: linux linux-esx (CVE-2021-3609)\n\n - An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the system or possibly escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3612)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.", "cvss3": {"exploitabilityScore": 1.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 7.8, "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "REQUIRED"}, "impactScore": 5.9}, "published": "2021-07-21T00:00:00", "type": "nessus", "title": "SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2021:2416-1)", "bulletinFamily": "scanner", "cvss2": {"severity": "HIGH", "exploitabilityScore": 3.9, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 7.2, "vectorString": "AV:L/AC:L/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "LOCAL", "authentication": "NONE"}, "impactScore": 10.0, "acInsufInfo": false, "obtainUserPrivilege": false}, "cvelist": ["CVE-2020-36385", "CVE-2021-22555", "CVE-2021-33909", "CVE-2021-3609", "CVE-2021-3612"], "modified": "2023-01-17T00:00:00", "cpe": ["p-cpe:/a:novell:suse_linux:cluster-md-kmdefault", "p-cpe:/a:novell:suse_linux:dlm-kmdefault", "p-cpe:/a:novell:suse_linux:gfs2-kmdefault", "p-cpe:/a:novell:suse_linux:kernel-default", "p-cpe:/a:novell:suse_linux:kernel-default-base", "p-cpe:/a:novell:suse_linux:kernel-default-devel", "p-cpe:/a:novell:suse_linux:kernel-default-extra", "p-cpe:/a:novell:suse_linux:kernel-default-kgraft", "p-cpe:/a:novell:suse_linux:kernel-default-kgraft-devel", "p-cpe:/a:novell:suse_linux:kernel-default-man", "p-cpe:/a:novell:suse_linux:kernel-devel", "p-cpe:/a:novell:suse_linux:kernel-macros", "p-cpe:/a:novell:suse_linux:kernel-obs-build", "p-cpe:/a:novell:suse_linux:kernel-source", "p-cpe:/a:novell:suse_linux:kernel-syms", "p-cpe:/a:novell:suse_linux:kgraft-patch-4_12_14-122_80-default", "p-cpe:/a:novell:suse_linux:ocfs2-kmdefault", "cpe:/o:novell:suse_linux:12"], "id": "SUSE_SU-2021-2416-1.NASL", "href": "https://www.tenable.com/plugins/nessus/151873", "sourceData": "#%NASL_MIN_LEVEL 70300\n##\n# (C) Tenable Network Security, Inc.\n#\n# The package checks in this plugin were extracted from\n# SUSE update advisory SUSE-SU-2021:2416-1.

(CVE-2020-36386)\n\n - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass\n RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users\n with the ability to start and control a VM to read/write random pages of memory and can result in local\n privilege escalation. (CVE-2021-22543)\n\n - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.\n This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name\n space (CVE-2021-22555)\n\n - fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer\n allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an\n unprivileged user, aka CID-8cae8cd89f05. (CVE-2021-33909)\n\n - kernel: race condition in net/can/bcm.c leads to local privilege escalation (CVE-2021-3609)\n\n - An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions\n before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the\n system or possibly escalate their privileges on the system. The highest threat from this vulnerability is\n to confidentiality, integrity, as well as system availability. (CVE-2021-3612)\n\n - arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest\n OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\",
