The version of kernel installed on the remote host is prior to 5.4.156-83.273. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2025-099 advisory.

    A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.
    (CVE-2021-20321)

    A flaw was found in the Linux kernel. A memory leak in the ccp-ops crypto driver can allow attackers to     cause a denial of service. This vulnerability is similar with the older CVE-2019-18808. The highest threat     from this vulnerability is to system availability. (CVE-2021-3744)

    A memory leak flaw was found in the Linux kernel's ccp_run_aes_gcm_cmd() function that allows an attacker     to cause a denial of service. The vulnerability is similar to the older CVE-2019-18808. The highest threat     from this vulnerability is to system availability. (CVE-2021-3764)

    An out-of-bounds (OOB) memory write flaw was found in prealloc_elems_and_freelist in kernel/bpf/stackmap.c     in the bpf in the Linux kernel. In this flaw, the multiplication to calculate the size could lead to an     integer overflow which could allow a local attacker, with a special user privilege, to gain access to out-     of-bounds memory leading to a system crash or a leak of internal kernel information. (CVE-2021-41864)

  - In the Linux kernel, the following vulnerability has been resolved: tty: n_gsm: fix possible out-of-bounds     in gsm0_receive() Assuming the following: - side A configures the n_gsm in basic option mode - side B     sends the header of a basic option mode frame with data length 1 - side A switches to advanced option mode
    - side B sends 2 data bytes which exceeds gsm->len Reason: gsm->len is not used in advanced option mode. -     side A switches to basic option mode - side B keeps sending until gsm0_receive() writes past gsm->buf     Reason: Neither gsm->state nor gsm->len have been reset after reconfiguration. Fix this by changing     gsm->count to gsm->len comparison from equal to less than. Also add upper limit checks against the     constant MAX_MRU in gsm0_receive() and gsm1_receive() to harden against memory corruption of gsm->len and     gsm->mru. All other checks remain as we still need to limit the data according to the user configuration     and actual payload size. (CVE-2024-36016)

  - In the Linux kernel, the following vulnerability has been resolved: rtnetlink: Correct nested     IFLA_VF_VLAN_LIST attribute validation Each attribute inside a nested IFLA_VF_VLAN_LIST is assumed to be a     struct ifla_vf_vlan_info so the size of such attribute needs to be at least of sizeof(struct     ifla_vf_vlan_info) which is 14 bytes. The current size validation in do_setvfinfo is against NLA_HDRLEN (4     bytes) which is less than sizeof(struct ifla_vf_vlan_info) so this validation is not enough and a too     small attribute might be cast to a struct ifla_vf_vlan_info, this might result in an out of bands read     access when accessing the saved (casted) entry in ivvl. (CVE-2024-36017)

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 5.10.82-83.359. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2024-049 advisory.

    A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could     happen if removing device (that is not common to remove video card physically without power-off, but same     happens if unbind the driver). (CVE-2020-27820)

    A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the     way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del()     together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A     privileged local user could use this flaw to crash the system or escalate their privileges on the system.
    (CVE-2021-3640)

    A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP     association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and     the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

    A race condition was found in the Linux kernel's ebpf verifier between bpf_map_update_elem and     bpf_map_freeze due to a missing lock in kernel/bpf/syscall.c. In this flaw, a local user with a special     privilege (cap_sys_admin or cap_bpf) can modify the frozen mapped address space. (CVE-2021-4001)

    A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some     regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the     memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

    A flaw heap buffer overflow in the Linux kernel's AMD Radeon graphics card driver was found in the way     user writes some malicious data to the AMD GPU Display Driver Debug Filesystem (to the VGA sub-directory     of the /sys/kernel/debug/ directory). A local user could use this flaw to crash the system or escalate     their privileges on the system. (CVE-2021-42327)
