  - 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)

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0618-1 advisory.

  - An issue was discovered in the Linux kernel through 5.16-rc6. netvsc_get_ethtool_stats in     drivers/net/hyperv/netvsc_drv.c lacks check of the return value of kvmalloc_array() and will cause the     null pointer dereference. (CVE-2022-3107)

  - An issue was discovered in the Linux kernel through 5.16-rc6. kfd_parse_subtype_iolink in     drivers/gpu/drm/amd/amdkfd/kfd_crat.c lacks check of the return value of kmemdup(). (CVE-2022-3108)

  - A vulnerability classified as critical was found in Linux Kernel. Affected by this vulnerability is the     function l2cap_reassemble_sdu of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The     manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The associated     identifier of this vulnerability is VDB-211087. (CVE-2022-3564)

  - An out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in     drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128     (or Dxxx)'.

  - 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)

  - 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)

  - The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176.

  - A vulnerability classified as critical was found in Linux Kernel. Affected by this vulnerability is the     function l2cap_reassemble_sdu of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The     manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The associated     identifier of this vulnerability is VDB-211087. (CVE-2022-3564)

  - 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)

  - 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)

  - 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).

The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0634-1 advisory.

  - Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow     unauthorized disclosure of information to an attacker with local user access via a side-channel analysis     of the data cache. (CVE-2017-5754)

  - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and     SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a     user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)

  - 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)

  - An out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in     drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128     (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing     a denial of service(DoS). (CVE-2022-36280)

  - 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)

  - 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)

  - The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176. We recommend upgrading past commit     a664ec9158eeddd75121d39c9a0758016097fa96 (CVE-2023-0045)

  - A use after free vulnerability exists in the ALSA PCM package in the Linux Kernel.
    SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 is missing locks that can be used in a use-after-free that can result     in a priviledge escalation to gain ring0 access from the system user. We recommend upgrading past commit     56b88b50565cd8b946a2d00b0c83927b7ebb055e (CVE-2023-0266)

  - 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)

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