The version of kernel installed on the remote host is prior to 5.10.205-194.804. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2024-047 advisory.

    A race condition leading to a use-after-free issue was found in the QXL driver in the Linux kernel.
    (CVE-2023-39198)

    An issue was discovered in the Linux kernel through 6.5.9. During a race with SQ thread exit, an     io_uring/fdinfo.c io_uring_show_fdinfo NULL pointer dereference can occur. (CVE-2023-46862)

    An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This flaw     allows a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that     results in kmalloc data to be printed (and potentially leaked) to the kernel ring buffer (dmesg).
    (CVE-2023-6121)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation.

    The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double     deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free.

    We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a. (CVE-2023-6817)

    A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be     exploited to achieve local privilege escalation.

    A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in     perf_read_group().

    We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b. (CVE-2023-6931)

    A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve     local privilege escalation.

    A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object     which is freed by another thread.

    We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1. (CVE-2023-6932)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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 :

  - A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited     to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate     filters in case of a perfect hashes while deleting the underlying structure which can later lead to double     freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.
    We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. (CVE-2023-1829)

  - A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address     prediction. This may result in speculative execution at an attacker-controlled address, potentially     leading to information disclosure. (CVE-2023-20569)

  - An issue was discovered in drivers/mtd/ubi/cdev.c in the Linux kernel 6.2. There is a divide-by-zero error     in do_div(sz,mtd->erasesize), used indirectly by ctrl_cdev_ioctl, when mtd->erasesize is 0.
    (CVE-2023-31085)

  - A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function     dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one     holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a     use-after-free issue, potentially leading to a denial of service or privilege escalation. (CVE-2023-39198)

  - An issue was discovered in the Linux kernel through 6.5.9. During a race with SQ thread exit, an     io_uring/fdinfo.c io_uring_show_fdinfo NULL pointer dereference can occur. (CVE-2023-46862)

  - A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm     scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific     socket configuration, which could allow a local user to crash the system or escalate their privileges on     the system. (CVE-2023-6176)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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

  - An issue was discovered in the Linux kernel through 6.0.10. In drivers/media/dvb-core/dvb_ca_en50221.c, a     use-after-free can occur is there is a disconnect after an open, because of the lack of a wait_event.
    (CVE-2022-45919)

  - A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited     to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate     filters in case of a perfect hashes while deleting the underlying structure which can later lead to double     freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.
    We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. (CVE-2023-1829)

  - Improper access control in the Intel(R) Ethernet Controller RDMA driver for linux before version 1.9.30     may allow an unauthenticated user to potentially enable escalation of privilege via network access.
    (CVE-2023-25775)

  - An issue was discovered in drivers/mtd/ubi/cdev.c in the Linux kernel 6.2. There is a divide-by-zero error     in do_div(sz,mtd->erasesize), used indirectly by ctrl_cdev_ioctl, when mtd->erasesize is 0.
    (CVE-2023-31085)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did     not validate the user mode controlled opt_num 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-2023-39189)

  - 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)

  - A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing     of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local     privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an     information disclosure. (CVE-2023-39194)

  - A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function     dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one     holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a     use-after-free issue, potentially leading to a denial of service or privilege escalation. (CVE-2023-39198)

  - An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro     could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to     arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash     the system or potentially escalate their privileges on the system. (CVE-2023-42753)

  - A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was     assumed to be associated with a device before calling __ip_options_compile, which is not always the case     if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash     the system. (CVE-2023-42754)

  - An issue was discovered in drivers/usb/storage/ene_ub6250.c for the ENE UB6250 reader driver in the Linux     kernel before 6.2.5. An object could potentially extend beyond the end of an allocation. (CVE-2023-45862)

  - 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 af_unix component can be exploited to achieve local     privilege escalation. The unix_stream_sendpage() function tries to add data to the last skb in the peer's     recv queue without locking the queue. Thus there is a race where unix_stream_sendpage() could access an     skb locklessly that is being released by garbage collection, resulting in use-after-free. We recommend     upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c. (CVE-2023-4622)

  - 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)

  - A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf)     component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an     event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory     locations outside of the allocated buffer. We recommend upgrading past commit     32671e3799ca2e4590773fd0e63aaa4229e50c06. (CVE-2023-5717)

  - A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two     threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline     enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This     could allow a local unprivileged user to escalate their privileges on the system. (CVE-2023-6546)

  - An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux     Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
    (CVE-2023-6606)

  - A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be     exploited to achieve local privilege escalation. A perf_event's read_size can overflow, leading to an heap     out-of-bounds increment or write in perf_read_group(). We recommend upgrading past commit     382c27f4ed28f803b1f1473ac2d8db0afc795a1b. (CVE-2023-6931)

  - A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve     local privilege escalation. A race condition can be exploited to cause a timer be mistakenly registered on     a RCU read locked object which is freed by another thread. We recommend upgrading past commit     e2b706c691905fe78468c361aaabc719d0a496f1. (CVE-2023-6932)

The version of kernel installed on the remote host is prior to 5.4.265-176.364. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2024-057 advisory.

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

    netfilter: nf_tables: double hook unregistration in netns path (CVE-2022-49558)

    A race condition leading to a use-after-free issue was found in the QXL driver in the Linux kernel.
    (CVE-2023-39198)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation.

    Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage     collection, it is possible to underflow the reference counter causing a use-after-free vulnerability.

    We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8. (CVE-2023-4244)

    When a router encounters an IPv6 packet too big to transmit to the next-hop, it returns an ICMP6 Packet     Too Big (PTB) message to the sender. The sender caches this updated Maximum Transmission Unit (MTU) so it     knows not to exceed this value when subsequently routing to the same host.

    In Linux kernels prior to 6.3, garbage collection is run on the IPv6 Destination Route Cache if the number     of entries exceeds a threshold when adding the destination to the cache. This garbage collection examines     every entry in the cache while holding a lock. In these affected kernel versions, a flood of the IPv6     ICMP6 PTB messages could cause high lock contention and increased CPU usage, leading to a Denial-of-     Service.

    The fix backports the garbage collection improvements from Linux kernel 6.3 by bringing the IPv6 code     closer to the IPv4 code, which does not have this issue.

    Patch: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=af6d10345ca76670c1b7c3     7799f0d5576ccef277 (CVE-2023-52340)

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

    netfilter: nft_set_rbtree: skip sync GC for new elements in this transaction

    An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This flaw     allows a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that     results in kmalloc data to be printed (and potentially leaked) to the kernel ring buffer (dmesg).

    A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's     deletion of SKB races with unix_stream_read_generic() on the socket that the SKB is queued on.
    (CVE-2023-6531)

    A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be     exploited to achieve local privilege escalation.

    A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in     perf_read_group().

    We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b. (CVE-2023-6931)

    A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve     local privilege escalation.

    A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object     which is freed by another thread.

    We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1. (CVE-2023-6932)

    A use-after-free issue was found in igmp_start_timer in net/ipv4/igmp.c in the network sub-component in     the Linux Kernel. This flaw allows a local user to observe a refcnt use-after-free issue when receiving an     igmp query packet, leading to a kernel information leak. (CVE-2024-0584)
