"The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as
referenced in the SUSE-SU-2022:2776-1 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)

  - 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

  - 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.
