{"id": "ALAS-2022-1852", "vendorId": null, "type": "amazon", "bulletinFamily": "unix", "title": "Important: kernel", "description": "**Issue Overview:**\n\nAn out-of-bounds write flaw was found in the Linux kernel&amp;rsquo;s framebuffer-based console driver functionality in the way a user triggers ioctl FBIOPUT_VSCREENINFO with malicious data. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2021-33655)\n\nA vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. (CVE-2021-4159)\n\nAn out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory. (CVE-2022-1462)\n\nA use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)\n\nA flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service. (CVE-2022-2153)\n\nA use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege escalation problem. (CVE-2022-2588)\n\nA firewall flaw that can bypass the Linux kernel's Netfilter functionality was found in how a user handles unencrypted IRC with nf_conntrack_irc configured. This flaw allows a remote user to gain unauthorized access to the system. (CVE-2022-2663)\n\nA race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\nA memory access flaw was found in the Linux kernel's XEN hypervisor for the virtual machine. This flaw allows a local user to crash the system or potentially escalate their privileges on the system. (CVE-2022-36123)\n\nAn issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\nA memory corruption flaw was found in the Linux kernel's Netfilter subsystem in the way a local user uses the libnetfilter_queue when analyzing a corrupted network packet. This flaw allows a local user to crash the system or a remote user to crash the system when the libnetfilter_queue is used by a local user. (CVE-2022-36946)\n\nA race condition in the Linux kernel's EFI capsule loader driver was found in the way it handled write and flush operations on the device node of the EFI capsule. A local user could potentially use this flaw to crash the system. (CVE-2022-40307)\n\n \n**Affected Packages:** \n\n\nkernel\n\n \n**Issue Correction:** \nRun _yum update kernel_ to update your system. \n\n\n \n\n\n**New Packages:**\n \n \n aarch64: \n

{"nessus": [{"lastseen": "2023-05-17T16:35:37", "description": "The version of kernel installed on the remote host is prior to 4.14.294-220.533. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1852 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 vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures.\n Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. (CVE-2021-4159)\n\n - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory. (CVE-2022-1462)\n\n - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)\n\n - A flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service. (CVE-2022-2153)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges. (CVE-2022-36123)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - An issue was discovered in the Linux kernel through 5.19.8. drivers/firmware/efi/capsule-loader.c has a race condition with a resultant use-after-free. (CVE-2022-40307)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)\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": "2022-10-10T00:00:00", "type": "nessus", "title": "Amazon Linux 2 : kernel (ALAS-2022-1852)", "bulletinFamily": "scanner", "cvss2": {}, "cvelist": ["CVE-2021-33655", "CVE-2021-4159", "CVE-2022-1462", "CVE-2022-1679", "CVE-2022-2153", "CVE-2022-2588", "CVE-2022-2663", "CVE-2022-3028", "CVE-2022-36123", "CVE-2022-36879", "CVE-2022-36946", "CVE-2022-39188", "CVE-2022-40307"], "modified": "2023-02-20T00:00:00", "cpe": ["p-cpe:/a:amazon:linux:kernel", "p-cpe:/a:amazon:linux:kernel-debuginfo", "p-cpe:/a:amazon:linux:kernel-debuginfo-common-aarch64", "p-cpe:/a:amazon:linux:kernel-debuginfo-common-x86_64", "p-cpe:/a:amazon:linux:kernel-devel", "p-cpe:/a:amazon:linux:kernel-headers", "p-cpe:/a:amazon:linux:kernel-livepatch-4.14.294-220.533", "p-cpe:/a:amazon:linux:kernel-tools", "p-cpe:/a:amazon:linux:kernel-tools-debuginfo", "p-cpe:/a:amazon:linux:kernel-tools-devel", "p-cpe:/a:amazon:linux:perf", "p-cpe:/a:amazon:linux:perf-debuginfo", "p-cpe:/a:amazon:linux:python-perf", "p-cpe:/a:amazon:linux:python-perf-debuginfo", "cpe:/o:amazon:linux:2"], "id": "AL2_ALAS-2022-1852.NASL", "href": "https://www.tenable.com/plugins/nessus/165990", "sourceData": "#%NASL_MIN_LEVEL 80900\n##\n# (C) Tenable, Inc.\n#\n# The descriptive text and package checks in this plugin were\n# extracted from Amazon Linux 2 Security Advisory ALAS-2022-1852.\n##\n\ninclude('compat.inc');\n\nif (description)\n{\n script_id(165990);\n script_version(\"1.5\");\n script_set_attribute(attribute:\"plugin_modification_date\", value:\"2023/02/20\");\n\n script_cve_id(\n \"CVE-2021-4159\",\n \"CVE-2021-33655\",\n \"CVE-2022-1462\",\n \"CVE-2022-1679\",\n \"CVE-2022-2153\",\n \"CVE-2022-2588\",\n \"CVE-2022-2663\",\n \"CVE-2022-3028\",\n \"CVE-2022-36123\",\n \"CVE-2022-36879\",\n \"CVE-2022-36946\",\n \"CVE-2022-39188\",\n \"CVE-2022-40307\"\n );\n\n script_name(english:\"Amazon Linux 2 : kernel (ALAS-2022-1852)\");\n\n script_set_attribute(attribute:\"synopsis\", value:\n\"The remote Amazon Linux 2 host is missing a security update.\");\n script_set_attribute(attribute:\"description\", value:\n\"The version of kernel installed on the remote host is prior to 4.14.294-220.533.

of bounds. (CVE-2021-33655)\n\n - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.\n (CVE-2021-33656)\n\n - A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures.\n Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. (CVE-2021-4159)\n\n - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory. (CVE-2022-1462)\n\n - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)\n\n - A flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service. (CVE-2022-2153)\n\n - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that allow attackers to crash linux kernel without any privileges. (CVE-2022-2318)\n\n - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.

(CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the related lock held, resulting in a small race window, which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory pages. (CVE-2022-33744)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)\n\n - An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an integer overflow and bypassing the size check. After that, because it is used as the third argument to copy_from_user(), a heap overflow may occur. (CVE-2022-39842)\n\n - An issue was discovered in the Linux kernel through 5.19.8. drivers/firmware/efi/capsule-loader.c has a race condition with a resultant use-after-free.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-036 advisory.\n\n - A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures.\n Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. (CVE-2021-4159)\n\n - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system.

"According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :\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 - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory. (CVE-2022-1462)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel (CVE-2022-20368)\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 4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.\n (CVE-2022-2964)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after- free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)\n\n - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17.

(CVE-2021-33655)\n\n - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a\n user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage\n of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read\n unauthorized random data from memory. (CVE-2022-1462)\n\n - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel\n (CVE-2022-20368)\n\n - Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to\n restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently\n allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass\n verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and\n unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for\n peripherals that do not verify firmware updates. We recommend upgrading past commit\n 4caae58406f8ceb741603eee460d79bacca9b1b5 (CVE-2022-2503)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow\n an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of\n actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()\n function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This\n flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and\n incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted\n IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet\n Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.\n (CVE-2022-2964)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where\n virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-\n free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)\n when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to\n potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read\n and copying it into a socket. (CVE-2022-3028)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in\n net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\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\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race\n condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale\n TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)\n\n - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users\n can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED\n situations. (CVE-2022-39189)\n\n - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation\n (CVE-2022-2586)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation\n (CVE-2022-2588)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security\nadvisory.

A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171)\n\n - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory. (CVE-2022-1462)\n\n - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data. (CVE-2022-2905)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - Found Linux Kernel flaw in the i740 driver. The Userspace program could pass any values to the driver through ioctl() interface. The driver doesn't check the value of 'pixclock', so it may cause a divide by zero error. (CVE-2022-3061)\n\n - There exists a use-after-free in io_uring in the Linux kernel. Signalfd_poll() and binder_poll() use a waitqueue whose lifetime is the current task. It will send a POLLFREE notification to all waiters before the queue is freed. Unfortunately, the io_uring poll doesn't handle POLLFREE. This allows a use-after-free to occur if a signalfd or binder fd is polled with io_uring poll, and the waitqueue gets freed. We recommend upgrading past commit fc78b2fc21f10c4c9c4d5d659a685710ffa63659 (CVE-2022-3176)\n\n - A race condition flaw was found in the Linux kernel sound subsystem due to improper locking. It could lead to a NULL pointer dereference while handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or member of the audio group) could use this flaw to crash the system, resulting in a denial of service condition (CVE-2022-3303)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)\n\n - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED situations. (CVE-2022-39189)\n\n - An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of service can occur upon binding to an already bound chain. (CVE-2022-39190)\n\n - An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an integer overflow and bypassing the size check. After that, because it is used as the third argument to copy_from_user(), a heap overflow may occur. (CVE-2022-39842)\n\n - An issue was discovered in the Linux kernel through 5.19.8. drivers/firmware/efi/capsule-loader.c has a race condition with a resultant use-after-free. (CVE-2022-40307)\n\n - A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD CPU that supports Secure Encrypted Virtualization (SEV).

The existing KVM SEV API has a vulnerability that allows a non-root\n (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD\n CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171)\n\n - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a\n user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage\n of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read\n unauthorized random data from memory. (CVE-2022-1462)\n\n - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user\n forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local\n user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and\n incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted\n IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the\n bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to\n gain unauthorized access to data. (CVE-2022-2905)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)\n when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to\n potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read\n and copying it into a socket. (CVE-2022-3028)\n\n - Found Linux Kernel flaw in the i740 driver. The Userspace program could pass any values to the driver\n through ioctl() interface. The driver doesn't check the value of 'pixclock', so it may cause a divide by\n zero error. (CVE-2022-3061)\n\n - There exists a use-after-free in io_uring in the Linux kernel. Signalfd_poll() and binder_poll() use a\n waitqueue whose lifetime is the current task. It will send a POLLFREE notification to all waiters before\n the queue is freed. Unfortunately, the io_uring poll doesn't handle POLLFREE. This allows a use-after-free\n to occur if a signalfd or binder fd is polled with io_uring poll, and the waitqueue gets freed. We\n recommend upgrading past commit fc78b2fc21f10c4c9c4d5d659a685710ffa63659 (CVE-2022-3176)\n\n - A race condition flaw was found in the Linux kernel sound subsystem due to improper locking. It could lead\n to a NULL pointer dereference while handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or\n member of the audio group) could use this flaw to crash the system, resulting in a denial of service\n condition (CVE-2022-3303)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in\n net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\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\n - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users\n can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED\n situations. (CVE-2022-39189)\n\n - An issue was discovered in net/netfilter/nf_tables_api.c in the Linux kernel before 5.19.6. A denial of\n service can occur upon binding to an already bound chain. (CVE-2022-39190)\n\n - An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in\n drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an\n integer overflow and bypassing the size check. After that, because it is used as the third argument to\n copy_from_user(), a heap overflow may occur. (CVE-2022-39842)\n\n - An issue was discovered in the Linux kernel through 5.19.8. drivers/firmware/efi/capsule-loader.c has a\n race condition with a resultant use-after-free. (CVE-2022-40307)\n\n - A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root\n (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD\n CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171) (CVE-2022-21505, CVE-2022-2585)\n\n - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user\n forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local\n user to crash or potentially escalate their privileges on the system. (CVE-2022-1679) (CVE-2022-2586)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation\n (CVE-2022-2588)\n\nNote that Nessus has not tested for these issues

(CVE-2022-36123)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in\n net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\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\n - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user\n forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local\n user to crash or potentially escalate their privileges on the system. (CVE-2022-1679) (CVE-2022-2586)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation\n (CVE-2022-2588)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security\nadvisory.

CVSS Vector (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) (CVE-2022-21385)\n\n - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)\n\n - Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)\n\n - An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)\n\n - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted IRC with nf_conntrack_irc configured. (CVE-2022-2663)\n\n - A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after- free and create a situation where it may be possible to escalate privileges on the system. (CVE-2022-2977)\n\n - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket. (CVE-2022-3028)\n\n - An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)\n\n - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.

It will send a POLLFREE notification to all waiters before the queue is freed. Unfortunately, the io_uring poll doesn't handle POLLFREE. This allows a use-after-free to occur if a signalfd or binder fd is polled with io_uring poll, and the waitqueue gets freed. We recommend upgrading past commit fc78b2fc21f10c4c9c4d5d659a685710ffa63659 (CVE-2022-3176)\n\n - A race condition flaw was found in the Linux kernel sound subsystem due to improper locking.

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.

(CVE-2022-39188)\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://bugzilla.suse.com/1177440\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1180153\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1188944\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1191881\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1194535\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1196616\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1197158\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1199482\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1199665\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1201019\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1201420\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1201705\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1201726\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1201948\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202096\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202097\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202154\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202335\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202346\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202347\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202393\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202396\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202672\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202897\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1202898\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1203098\");\n script_set_attribute(attribute:\"see_also\", value:\"https://bugzilla.suse.com/1203107\");\n #
