"The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as
referenced in the SUSE-SU-2022:2854-1 advisory.

  - 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)

  - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use
    after free both read or write when non synchronized between cleanup routine and firmware download routine.
    (CVE-2022-1734)

  - st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has
    EVT_TRANSACTION buffer overflows because of untrusted length parameters. (CVE-2022-26490)

  - mcba_usb_start_xmit in drivers/net/can/usb/mcba_usb.c in the Linux kernel through 5.17.1 has a double
    free. (CVE-2022-28389)

  - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.
    (CVE-2022-28390)

  - network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data
    Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further
    processing to nevertheless be freed. (CVE-2022-33743)

  - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init
    (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different
    vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an
    unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data
    in net/netfilter/nf_tables_api.c. (CVE-2022-34918)

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