"The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple
vulnerabilities as referenced in the SUSE-SU-2023:4347-1 advisory.

  - An issue was discovered in the Linux kernel before 5.8.6. drivers/media/cec/core/cec-api.c leaks one byte
    of kernel memory on specific hardware to unprivileged users, because of directly assigning log_addrs with
    a hole in the struct. (CVE-2020-36766)

  - A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS
    transfers response data to a system call, there are still local variable points to the memory region, and
    if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a
    denial of service. (CVE-2023-1192)

  - A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel's IPv6
    functionality when a user makes a new kind of SYN flood attack. A user located in the local network or
    with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up
    to 95%. (CVE-2023-1206)

  - A use-after-free flaw was found in xen_9pfs_front_removet in net/9p/trans_xen.c in Xen transport for 9pfs
    in the Linux Kernel. This flaw could allow a local attacker to crash the system due to a race problem,
    possibly leading to a kernel information leak. (CVE-2023-1859)

  - An issue was discovered in drivers/mtd/ubi/cdev.c in the Linux kernel 6.2. There is a divide-by-zero error
    in do_div(sz,mtd->erasesize), used indirectly by ctrl_cdev_ioctl, when mtd->erasesize is 0.
    (CVE-2023-31085)

  - The vulnerability exists due to improper event handling in Linux kernel. A malicious guest can disable
    paravirtualized device to cause a deadlock in a backend domain (other than dom0). (CVE-2023-34324)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did
    not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN)
    attacker to trigger an out-of-bounds read, leading to a crash or information disclosure. (CVE-2023-39189)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the
    fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds
    read by setting the size fields with a value beyond the array boundaries, leading to a crash or
    information disclosure. (CVE-2023-39192)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the
    flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds
    read, leading to a crash or information disclosure. (CVE-2023-39193)

  - A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing
    of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local
    privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an
    information disclosure. (CVE-2023-39194)

  - An issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before
    6.4.10. There is a use-after-free because the children of an sk are mishandled. (CVE-2023-40283)

  - A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was
    assumed to be associated with a device before calling __ip_options_compile, which is not always the case
    if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash
    the system. (CVE-2023-42754)

  - An issue was discovered in drivers/usb/storage/ene_ub6250.c for the ENE UB6250 reader driver in the Linux
    kernel before 6.2.5. An object could potentially extend beyond the end of an allocation. (CVE-2023-45862)

  - A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local
    privilege escalation. The unix_stream_sendpage() function tries to add data to the last skb in the peer's
    recv queue without locking the queue. Thus there is a race where unix_stream_sendpage() could access an
    skb locklessly that is being released by garbage collection, resulting in use-after-free. We recommend
    upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c. (CVE-2023-4622)

  - A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control)
    component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve
    (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call
    vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling
    pointer that can cause a use-after-free. We recommend upgrading past commit
    b3d26c5702c7d6c45456326e56d2ccf3f103e60f. (CVE-2023-4623)

  - A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to
    achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending
    network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug
    and lack of error checking in agg_dequeue(). We recommend upgrading past commit
    8fc134fee27f2263988ae38920bc03da416b03d8. (CVE-2023-4921)
