The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Drivers: hv: vmbus: Don't dereference ACPI root object handle Since the commit referenced in the Fixes:
    tag below the VMBus client driver is walking the ACPI namespace up from the VMBus ACPI device to the ACPI     namespace root object trying to find Hyper-V MMIO ranges. However, if it is not able to find them it ends     trying to walk resources of the ACPI namespace root object itself. This object has all-ones handle, which     causes a NULL pointer dereference in the ACPI code (from dereferencing this pointer with an offset). This     in turn causes an oops on boot with VMBus host implementations that do not provide Hyper-V MMIO ranges in     their VMBus ACPI device or its ancestors. The QEMU VMBus implementation is an example of such     implementation. I guess providing these ranges is optional, since all tested Windows versions seem to be     able to use VMBus devices without them. Fix this by explicitly terminating the lookup at the ACPI     namespace root object. Note that Linux guests under KVM/QEMU do not use the Hyper-V PV interface by     default - they only do so if the KVM PV interface is missing or disabled.

Note that Nessus relies on the presence of the package as reported by the vendor.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-356 advisory.

    An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

    nftables out-of-bounds read in nf_osf_match_one() (CVE-2023-39189)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the     fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds     read by setting the size fields with a value beyond the array boundaries, leading to a crash or     information disclosure. (CVE-2023-39192)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the     flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds     read, leading to a crash or information disclosure. (CVE-2023-39193)

    An integer overflow in kmalloc_reserve() in the Linux kernel may allow a local user to crash the system,     or in some cases obtain code execution in kernel space. (CVE-2023-42752)

    The upstream commit describes this issue as follows:

    The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can lead to the use of wrong     `CIDR_POS(c)` for calculating array offsets, which can lead to integer underflow. As a result, it leads to     slab out-of-bound access. (CVE-2023-42753)

    A flaw was found in rsvp_change(). The root cause is an slab-out-of-bound access, but since the offset to     the original pointer is an `unsign int` fully controlled by users, the behavior is usually a wild pointer     access. (CVE-2023-42755)

    An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel     before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)

    A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control)     component can be exploited to achieve local privilege escalation.

    If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing     curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in     update_vf(). This leaves a dangling pointer that can cause a use-after-free.

    We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f. (CVE-2023-4623)

    A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to     achieve local privilege escalation.

    When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free     in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in     agg_dequeue().

    We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8. (CVE-2023-4921)

    In the Linux kernel, the following vulnerability has been resolved:

    netfilter: nftables: exthdr: fix 4-byte stack OOB write

    If priv->len is a multiple of 4, then dst[len / 4] can write pastthe destination array which leads to     stack corruption.

    This construct is necessary to clean the remainder of the registerin case ->len is NOT a multiple of the     register size, so make itconditional just like nft_payload.c does.

    The bug was added in 4.1 cycle and then copied/inherited whentcp/sctp and ip option support was added.
