  - Guests can trigger NIC interface reset/abort/crash via netback It is possible for a guest to trigger a NIC     interface reset/abort/crash in a Linux based network backend by sending certain kinds of packets. It     appears to be an (unwritten?) assumption in the rest of the Linux network stack that packet protocol     headers are all contained within the linear section of the SKB and some NICs behave badly if this is not     the case. This has been reported to occur with Cisco (enic) and Broadcom NetXtrem II BCM5780 (bnx2x)     though it may be an issue with other NICs/drivers as well. In case the frontend is sending requests with     split headers, netback will forward those violating above mentioned assumption to the networking core,     resulting in said misbehavior.

    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 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)

  - 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)

  - In rndis_query_oid in drivers/net/wireless/rndis_wlan.c in the Linux kernel through 6.1.5, there is an     integer overflow in an addition. (CVE-2023-23559)

  - 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) (CVE-2023-0179)

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

The version of kernel installed on the remote host is prior to 5.15.90-54.138. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-013 advisory.

  - 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)

  - A flaw NULL Pointer Dereference in the Linux kernel NTFS3 driver function attr_punch_hole() was found. A     local user could use this flaw to crash the system. (CVE-2022-4842)

  - In the Linux kernel before 6.1.3, fs/ntfs3/inode.c does not validate the attribute name offset. An     unhandled page fault may occur. (CVE-2022-48424)

  - 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 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)

  - Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec     allowing a user to bypass the access_ok check and pass a kernel pointer to copy_from_user(). This would     allow an attacker to leak information. We recommend upgrading beyond commit     74e19ef0ff8061ef55957c3abd71614ef0f42f47 (CVE-2023-0459)

  - There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a     use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can     install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this     socket is disconnected and reused as a listener. If a new socket is created from the listener, the context     is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend     upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

  - 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)

  - In the Linux kernel 6.0.8, there is a use-after-free in run_unpack in fs/ntfs3/run.c, related to a     difference between NTFS sector size and media sector size. (CVE-2023-26544)

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