advisory.\n\n - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds. (CVE-2021-33655)\n\n - A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem. (CVE-2022-1012)\n\n - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. (CVE-2022-1729)\n\n - Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates.

We recommend upgrading past commit\n 4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)\n\n - The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are\n used. (CVE-2022-32296)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote\n attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte\n nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\", value:\"https://ubuntu.com/security/notices/USN-5622-1\");\n script_set_attribute(attribute:\"solution\", value:\n\"Update the affected kernel package.\");\n script_set_cvss_base_vector(\"CVSS2#AV:L/AC:L/Au:N/C:P/I:N/A:N\");\n script_set_cvss_temporal_vector(\"CVSS2#E:U/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:U/RL:O/RC:C\");\n script_set_attribute(attribute:\"cvss_score_source\", value:\"CVE-2022-32296\");\n script_set_attribute(attribute:\"cvss3_score_source\", value:\"CVE-2022-1012\");\n\n script_set_attribute(attribute:\"exploitability_ease\", value:\"No known exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"false\");\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2022/05/31\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2022/09/21\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2022/09/21\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:canonical:ubuntu_linux:18.04:-:lts\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:canonical:ubuntu_linux:20.04:-:lts\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1033-ibm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1046-bluefield\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1053-gkeop\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1070-raspi\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1075-kvm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1083-oracle\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1085-aws\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-1091-azure\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-126-generic\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-126-generic-lpae\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-5.4.0-126-lowlatency\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-aws\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-azure\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-bluefield\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-generic\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-generic-lpae\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-gkeop\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-ibm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-kvm\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-lowlatency\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-oracle\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:canonical:ubuntu_linux:linux-image-raspi\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_family(english:\"Ubuntu Local Security Checks\");\n\n script_copyright(english:\"Ubuntu Security Notice (C) 2022-2023 Canonical, Inc. / NASL script (C) 2022-2023 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n\n script_dependencies(\"ssh_get_info.nasl\", \"linux_alt_patch_detect.nasl\");\n script_require_keys(\"Host/cpu\", \"Host/Ubuntu\", \"Host/Ubuntu/release\", \"Host/Debian/dpkg-l\");\n\n exit(0);\n}\n\ninclude('debian_package.inc');\ninclude('ksplice.inc');\n\nif ( !

installed on the remote host is prior to 5.4.196-108.356. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-026 advisory.\n\n - Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. (CVE-2022-29581)\n\n - A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494)\n\n - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.\n This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)\n\n - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc. (CVE-2022-1729)\n\n - The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state. (CVE-2022-28893)\n\nNote that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.", "cvss3": {}, "published": "2022-06-10T00:00:00", "type": "nessus", "title": "Amazon Linux 2 : kernel (ALASKERNEL-5.4-2022-026)", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2022-0494", "CVE-2022-0854", "CVE-2022-1729", "CVE-2022-1836", "CVE-2022-2639", "CVE-2022-28893", "CVE-2022-29581", "CVE-2023-1838"], "modified": "2023-05-02T00:00:00", "cpe": ["p-cpe:/a:amazon:linux:bpftool", "p-cpe:/a:amazon:linux:bpftool-debuginfo", "p-cpe:/a:amazon:linux:kernel", "p-cpe
