  - Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel     (CVE-2022-20368)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - kernel: nf_tables cross-table potential use-after-free may lead to local privilege escalation     (CVE-2022-2586)

  - kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation     (CVE-2022-2588)

(CVE-2022-2977)

  - A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. The issue results from     the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length     heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary     code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged     code on the target system to exploit this vulnerability. (CVE-2022-2991)

  - 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)

  - A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers     em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system     or potentially escalate their privileges on the system. (CVE-2022-3239)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2023:0002 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2021-4037:
    A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that     allows local users to create files for the XFS file-system with an unintended group ownership and with     group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a     certain group and is writable by a user who is not a member of this group. This can lead to excessive     permissions granted in case when they should not. This vulnerability is similar to the previous     CVE-2018-13405 and adds the missed fix for the XFS.

    CVE-2022-0171:
    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-2022-1679:
    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-2022-2585:
    A use-after-free flaw was found in the Linux kernel?s POSIX CPU timers functionality in the way a user     creates and then deletes the timer in the non-leader thread of the program. This flaw allows a local user     to crash or potentially escalate their privileges on the system.

    CVE-2022-2586:
    A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in     the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the     time of table deletion, possibly leading to local privilege escalation.

    CVE-2022-2588:
    A 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-2022-2602:
    A vulnerability was found in PostgreSQL. This attack requires permission to create non-temporary objects     in at least one schema, the ability to lure or wait for an administrator to create or update an affected     extension in that schema, and the ability to lure or wait for a victim to use the object targeted in     CREATE OR REPLACE or CREATE IF NOT EXISTS. Given all three prerequisites, this flaw allows an attacker to     run arbitrary code as the victim role, which may be a superuser.

    CVE-2022-26373:
    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-2022-2663:
    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-2022-2905:
    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-2022-2978:
    A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function     security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use     this flaw to crash the system or potentially escalate their privileges on the system.

    CVE-2022-3028:
    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-2022-3061:
    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-2022-3169:
    A flaw was found in the Linux kernel. A denial of service flaw may occur if there is a consecutive request     of the NVME_IOCTL_RESET and the NVME_IOCTL_SUBSYS_RESET through the device file of the driver, resulting     in a PCIe link disconnect.

    CVE-2022-3176:
    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
