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

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 4.14.326-245.539. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2264 advisory.

    A flaw was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem). This issue     may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in     xfrm_update_ae_params(), leading to a possible kernel crash and denial of service. (CVE-2023-3772)

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

    When fw_change() is called on an existing filter, the whole tcf_result struct is always copied into the     new instance of the filter. This causes a problem when updating a filter bound to a class, as     tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the     still referenced class and allowing it to be deleted, leading to a use-after-free.

    We recommend upgrading past commit 76e42ae831991c828cffa8c37736ebfb831ad5ec. (CVE-2023-4207)

    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)

    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 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)

    run bpftrace -e 'kfunc:xxx {}', this will fail (expected for now); 3. repeat #2 => gpf. This is because     the entry is added to direct_functions, but not removed. Fix this by remove the entry from     direct_functions when register_ftrace_direct fails. Also remove the last trailing space from ftrace.c, so     we don't have to worry about it anymore. (CVE-2022-49402)

  - In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3: Fix refcount leak in     gic_populate_ppi_partitions of_find_node_by_phandle() returns a node pointer with refcount incremented, we     should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.
    (CVE-2022-49715)

  - In the Linux kernel, the following vulnerability has been resolved: cpufreq: CPPC: Add u64 casts to avoid     overflowing The fields of the _CPC object are unsigned 32-bits values. To avoid overflows while using
    _CPC's values, add 'u64' casts. (CVE-2022-49750)

  - In the Linux kernel, the following vulnerability has been resolved: net: stream: purge sk_error_queue in     sk_stream_kill_queues() Changheon Lee reported TCP socket leaks, with a nice repro. It seems we leak TCP     sockets with the following sequence: 1) SOF_TIMESTAMPING_TX_ACK is enabled on the socket. Each ACK will     cook an skb put in error queue, from __skb_tstamp_tx(). __skb_tstamp_tx() is using skb_clone(), unless     SOF_TIMESTAMPING_OPT_TSONLY was also requested. 2) If the application is also using MSG_ZEROCOPY, then we     put in the error queue cloned skbs that had a struct ubuf_info attached to them. Whenever an struct     ubuf_info is allocated, sock_zerocopy_alloc() does a sock_hold(). As long as the cloned skbs are still in     sk_error_queue, socket refcount is kept elevated. 3) Application closes the socket, while error queue is     not empty. Since tcp_close() no longer purges the socket error queue, we might end up with a TCP socket     with at least one skb in error queue keeping the socket alive forever. This bug can be (ab)used to consume     all kernel memory and freeze the host. We need to purge the error queue, with proper synchronization     against concurrent writers. (CVE-2022-50838)

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Add preempt_count_{sub,add} into     btf id deny list The recursion check in __bpf_prog_enter* and __bpf_prog_exit* leave     preempt_count_{sub,add} unprotected.
