multiple vulnerabilities:\n\n - A flaw null pointer dereference in the Linux kernel cgroupv2 subsystem in versions before 5.7.10 was found in the way when reboot the system. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2020-14356)\n\n - A flaw was found in the Linux kernel's futex implementation. This flaw allows a local attacker to corrupt system memory or escalate their privileges when creating a futex on a filesystem that is about to be unmounted. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-14381)\n\n - In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.\n (CVE-2020-25211)\n\n - A locking issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.\n drivers/tty/tty_jobctrl.c allows a use-after-free attack against TIOCSPGRP, aka CID-54ffccbf053b.\n (CVE-2020-29661)\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 - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads to writing an arbitrary value. (CVE-2021-33033)\n\n - nbd_add_socket in drivers/block/nbd.c in the Linux kernel through 5.10.12 has an ndb_queue_rq use-after- free that could be triggered by local attackers (with access to the nbd device) via an I/O request at a certain point during device setup, aka CID-b98e762e3d71. (CVE-2021-3348)\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\n - arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)\n\n - net/sunrpc/xdr.c in the Linux kernel before 5.13.4 allows remote attackers to cause a denial of service (xdr_set_page_base slab-out-of-bounds access) by performing many NFS 4.2 READ_PLUS operations.\n (CVE-2021-38201)\n\nNote that Nessus has not tested for these issues 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": "LOW", "baseScore": 7.8, "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "version": "3.1", "userInteraction": "NONE"}, "impactScore": 5.9}, "published": "2022-05-09T00:00:00", "type": "nessus", "title": "NewStart CGSL MAIN 6.02 : kernel Multiple Vulnerabilities (NS-SA-2022-0073)", "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-2020-14356", "CVE-2020-14381", "CVE-2020-25211", "CVE-2020-29661", "CVE-2021-22555", "CVE-2021-23133", "CVE-2021-33033", "CVE-2021-3348", "CVE-2021-3612", "CVE-2021-37576", "CVE-2021-38201"], "modified": "2023-01-13T00:00:00", "cpe": ["p-cpe:/a:zte:cgsl_main:bpftool", "p-cpe:/a:zte:cgsl_main:bpftool-debuginfo", "p-cpe:/a:zte:cgsl_main:kernel", "p-cpe:/a:zte:cgsl_main:kernel-abi-whitelists", "p-cpe:/a:zte:cgsl_main:kernel-core", "p-cpe:/a:zte:cgsl_main:kernel-cross-headers", "p-cpe:/a:zte:cgsl_main:kernel-debug", "p-cpe:/a:zte:cgsl_main:kernel-debug-core", "p-cpe:/a:zte:cgsl_main:kernel-debug-debuginfo", "p-cpe:/a:zte:cgsl_main:kernel-debug-devel", "p-cpe:/a:zte:cgsl_main:kernel-debug-modules", "p-cpe:/a:zte:cgsl_main:kernel-debug-modules-extra", "p-cpe:/a:zte:cgsl_main:kernel-debug-modules-internal", "p-cpe:/a:zte:cgsl_main:kernel-debuginfo", "p-cpe:/a:zte:cgsl_main:kernel-debuginfo-common-x86_64", "p-cpe:/a:zte:cgsl_main:kernel-devel", "p-cpe:/a:zte:cgsl_main:kernel-headers", "p-cpe:/a:zte:cgsl_main:kernel-ipaclones-internal", "p-cpe:/a:zte:cgsl_main:kernel-modules", "p-cpe:/a:zte:cgsl_main:kernel-modules-extra", "p-cpe:/a:zte:cgsl_main:kernel-modules-internal", "p-cpe:/a:zte:cgsl_main:kernel-selftests-internal", "p-cpe:/a:zte:cgsl_main:kernel-sign-keys", "p-cpe:/a:zte:cgsl_main:kernel-tools", "p-cpe:/a:zte:cgsl_main:kernel-tools-debuginfo", "p-cpe:/a:zte:cgsl_main:kernel-tools-libs", "p-cpe:/a:zte:cgsl_main:kernel-tools-libs-devel", "p-cpe:/a:zte:cgsl_main:perf", "p-cpe:/a:zte:cgsl_main:perf-debuginfo", "p-cpe:/a:zte:cgsl_main:python3-perf", "p-cpe:/a:zte:cgsl_main:python3-perf-debuginfo", "cpe:/o:zte:cgsl_main:6"], "id": "NEWSTART_CGSL_NS-SA-2022-0073_KERNEL.NASL", "href": "https://www.tenable.com/plugins/nessus/160769", "sourceData": "##\n# (C) Tenable, Inc.\n#\n# The descriptive text and package checks in this plugin were\n# extracted from ZTE advisory NS-SA-2022-0073.

Only privileged local users (with\n CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.\n (CVE-2021-3679)\n\n - In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because\n of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a\n side-channel attack, aka CID-9183671af6db. (CVE-2021-33624)\n\n - In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from\n kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects\n the possibility of uninitialized memory locations on the BPF stack. (CVE-2021-34556)\n\n - In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from\n kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store\n operation does not necessarily occur before a store operation that has an attacker-controlled value.\n (CVE-2021-35477)\n\n - hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev\n without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.\n (CVE-2021-37159)\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\n - ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss\n can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:\n the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the\n length validation was added solely for robustness in the face of anomalous host OS behavior.\n (CVE-2021-38160)\n\n - fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which\n allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for\n those servers to be unreachable during trunking detection. (CVE-2021-38199)\n\n - net/sunrpc/xdr.c in the Linux kernel before 5.13.4 allows remote attackers to cause a denial of service\n (xdr_set_page_base slab-out-of-bounds access) by performing many NFS 4.2 READ_PLUS operations.\n (CVE-2021-38201)\n\n - drivers/usb/host/max3421-hcd.c in the Linux kernel before 5.13.6 allows physically proximate attackers to\n cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain\n situations. (CVE-2021-38204)\n\n - drivers/net/ethernet/xilinx/xilinx_emaclite.c in the Linux kernel before 5.13.3 makes it easier for\n attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM\n pointer). (CVE-2021-38205)\n\n - loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain\n privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by\n using /proc//maps for exploitation.

(CVE-2019-19447)\n\n - A flaw null pointer dereference in the Linux kernel cgroupv2 subsystem in versions before 5.7.10 was found in the way when reboot the system. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2020-14356)\n\n - A flaw was found in the Linux kernel's futex implementation. This flaw allows a local attacker to corrupt system memory or escalate their privileges when creating a futex on a filesystem that is about to be unmounted. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-14381)\n\n - The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c. (CVE-2020-16166)\n\n - In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.\n (CVE-2020-25211)\n\n - A locking issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.\n drivers/tty/tty_jobctrl.c allows a use-after-free attack against TIOCSPGRP, aka CID-54ffccbf053b.\n (CVE-2020-29661)\n\n - In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-173843328References: Upstream kernel (CVE-2021-0512)\n\n - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local 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 space (CVE-2021-22555)\n\n - A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket. (CVE-2021-23133)\n\n - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads to writing an arbitrary value. (CVE-2021-33033)\n\n - nbd_add_socket in drivers/block/nbd.c in the Linux kernel through 5.10.12 has an ndb_queue_rq use-after- free that could be triggered by local attackers (with access to the nbd device) via an I/O request at a certain point during device setup, aka CID-b98e762e3d71. (CVE-2021-3348)\n\n - .A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. This race condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root.\n (CVE-2021-3609)\n\n - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.\n This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)\n\n - arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)\n\n - net/sunrpc/xdr.c in the Linux kernel before 5.13.4 allows remote attackers to cause a denial of service (xdr_set_page_base slab-out-of-bounds access) by performing many NFS 4.2 READ_PLUS operations.\n (CVE-2021-38201)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them. (CVE-2021-4155)\n\n - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.\n (CVE-2022-0492)\n\n - A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)\n\n - A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat.

This race\n condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root.\n (CVE-2021-3609)\n\n - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking\n subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.\n This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat\n from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)\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\n - net/sunrpc/xdr.c in the Linux kernel before 5.13.4 allows remote attackers to cause a denial of service\n (xdr_set_page_base slab-out-of-bounds access) by performing many NFS 4.2 READ_PLUS operations.\n (CVE-2021-38201)\n\n - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket\n file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race\n condition. This flaw allows a local user to crash the system or escalate their privileges on the system.\n This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)\n\n - A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size\n increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS\n filesystem otherwise not accessible to them. (CVE-2021-4155)\n\n - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the\n kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups\n v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.\n (CVE-2022-0492)\n\n - A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper\n initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus\n contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache\n backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)\n\n - A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and\n net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap\n objects and may cause a local privilege escalation threat.
