The version of kernel installed on the remote host is prior to 5.10.118-111.515. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-014 advisory.

  - 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)

  - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.
    This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)

  - 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)

  - A use-after-free flaw was found in the Linux kernel's io_uring subsystem in the way a user sets up a ring     with IORING_SETUP_IOPOLL with more than one task completing submissions on this ring. This flaw allows a     local user to crash or escalate their privileges on the system. (CVE-2022-1786)

  - In (TBD) of (TBD), there is a possible way to corrupt kernel memory due to a use after free. 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-220738351References:
    Upstream kernel (CVE-2022-20568)

  - kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of     the availability of pointer arithmetic via certain *_OR_NULL pointer types. (CVE-2022-23222)

  - 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)

  - 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)

  - 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)

  - An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause     a denial of service (panic) because input_set_capability mishandles the situation in which an event code     falls outside of a bitmap. (CVE-2022-48619)

  - A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in virtio network     subcomponent in the Linux kernel due to a double fget. This flaw could allow a local attacker to crash the     system, and could even lead to a kernel information leak problem. (CVE-2023-1838)

  - A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in     VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash     the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a     kernel information leak problem. (CVE-2023-4387)

  - A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in     the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with     normal user privilege to cause a denial of service due to a missing sanity check during cleanup.
    (CVE-2023-4459)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - In (TBD) of (TBD), there is a possible way to corrupt kernel memory due to a use after free. 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-220738351References:
    Upstream kernel (CVE-2022-20568)

  - A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks.
    L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after     running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can     execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past     commit 2e7eab81425a (CVE-2022-2196)

  - An issue was discovered in the Linux kernel through 5.16-rc6. free_charger_irq() in     drivers/power/supply/wm8350_power.c lacks free of WM8350_IRQ_CHG_FAST_RDY, which is registered in     wm8350_init_charger(). (CVE-2022-3111)

  - A use-after-free flaw was found in the Linux kernel's SGI GRU driver in the way the first     gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the     gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate     their privileges on the system. (CVE-2022-3424)

  - A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card     system resource overload, causing a fail in the intel_gvt_dma_map_guest_page function. This issue could     allow a local user to crash the system. (CVE-2022-3707)

  - In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused     by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)

  - A flaw incorrect access control in the Linux kernel USB core subsystem was found in the way user attaches     usb device. A local user could use this flaw to crash the system. (CVE-2022-4662)

  - There exists a use-after-free vulnerability in the Linux kernel through io_uring and the IORING_OP_SPLICE     operation. If IORING_OP_SPLICE is missing the IO_WQ_WORK_FILES flag, which signals that the operation     won't use current->nsproxy, so its reference counter is not increased. This assumption is not always true     as calling io_splice on specific files will call the get_uts function which will use current->nsproxy     leading to invalidly decreasing its reference counter later causing the use-after-free vulnerability. We     recommend upgrading to version 5.10.160 or above (CVE-2022-4696)

  - In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows     an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control     configuration that is set up with 'tc qdisc' and 'tc class' commands. This affects qdisc_graft in     net/sched/sch_api.c. (CVE-2022-47929)

  - An issue was discovered in the Linux kernel 5.10.x before 5.10.155. A use-after-free in io_sqpoll_wait_sq     in fs/io_uring.c allows an attacker to crash the kernel, resulting in denial of service. finish_wait can     be skipped. An attack can occur in some situations by forking a process and then quickly terminating it.
    NOTE: later kernel versions, such as the 5.15 longterm series, substantially changed the implementation of     io_sqpoll_wait_sq. (CVE-2022-47946)

  - A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could     allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to     the root user via arbitrary code execution. (CVE-2023-0179)

  - A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

  - A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race     problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 ('net: sched: fix race     condition in qdisc_graft()') not applied yet, then kernel could be affected. (CVE-2023-0590)

  - In binder_vma_close of binder.c, there is a possible use after free due to improper locking. 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-254837884References:
    Upstream kernel (CVE-2023-20928)

  - cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

  - atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)
