The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2377-1 advisory.

  - The Linux kernel through 5.8.13 does not properly enforce the Secure Boot Forbidden Signature Database     (aka dbx) protection mechanism. This affects certs/blacklist.c and certs/system_keyring.c.
    (CVE-2020-26541)

  - An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in     the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could     potentially use this flaw to crash the system or escalate privileges on the system. (CVE-2021-4157)

  - A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the     small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of     service problem. (CVE-2022-1012)

  - A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user     forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local     user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)

  - In lg_probe and related functions of hid-lg.c and other USB HID files, there is a possible out of bounds     read due to improper input validation. This could lead to local information disclosure if a malicious USB     HID device were plugged in, with no additional execution privileges needed. User interaction is not needed     for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-188677105References: Upstream     kernel (CVE-2022-20132)

  - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead     to local escalation of privilege when opening and closing inet sockets with no additional execution     privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)

  - In lock_sock_nested of sock.c, there is a possible use after free due to a race condition. This could lead     to local escalation of privilege with System execution privileges needed. User interaction is not needed     for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-174846563References: Upstream     kernel (CVE-2022-20154)

  - There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that     allow attackers to crash linux kernel without any privileges. (CVE-2022-2318)

  - Linux disk/nic frontends data leaks T[his CNA information record relates to multiple CVEs; the text     explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device     frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740).
    Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to     unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend     (CVE-2022-33741, CVE-2022-33742). (CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742)

  - Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution     under certain microarchitecture-dependent conditions. (CVE-2022-29900)

  - Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their     retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can     hijack return instructions to achieve arbitrary speculative code execution under certain     microarchitecture-dependent conditions. (CVE-2022-29901)

  - drivers/block/floppy.c in the Linux kernel before 5.17.6 is vulnerable to a denial of service, because of     a concurrency use-after-free flaw after deallocating raw_cmd in the raw_cmd_ioctl function.
    (CVE-2022-33981)

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