"The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2022:1407-1 advisory.

  - In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota
    tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a
    corrupted quota file. (CVE-2021-45868)

  - A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to
    userspace. (CVE-2022-0850)

  - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.
    This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in
    privilege escalation. (CVE-2022-1011)

  - A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a
    use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel
    information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)

  - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers
    concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM
    for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the
    system. (CVE-2022-1048)

  - A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain
    privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past
    commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 (CVE-2022-1055)

  - A use-after-free vulnerability was found in the Linux kernel in drivers/net/hamradio. This flaw allows a
    local attacker with a user privilege to cause a denial of service (DOS) when the mkiss or sixpack device
    is detached and reclaim resources early. (CVE-2022-1195)

  - A use-after-free vulnerabilitity was discovered in drivers/net/hamradio/6pack.c of linux that allows an
    attacker to crash linux kernel by simulating ax25 device using 6pack driver from user space.
    (CVE-2022-1198)

  - A flaw was found in the Linux kernel. This flaw allows an attacker to crash the Linux kernel by simulating
    amateur radio from the user space, resulting in a null-ptr-deref vulnerability and a use-after-free
    vulnerability. (CVE-2022-1199)

  - A NULL pointer dereference flaw was found in the Linux kernel's Amateur Radio AX.25 protocol functionality
    in the way a user connects with the protocol. This flaw allows a local user to crash the system.
    (CVE-2022-1205)

  - A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and
    net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap
    objects and may cause a local privilege escalation threat. (CVE-2022-27666)

  - usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double
    free. (CVE-2022-28388)

  - 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)
