"The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2024:0115-1 advisory.

  - Bluetooth legacy BR/EDR PIN code pairing in Bluetooth Core Specification 1.0B through 5.2 may permit an
    unauthenticated nearby device to spoof the BD_ADDR of the peer device to complete pairing without
    knowledge of the PIN. (CVE-2020-26555)

  - An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue
    may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that
    results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
    (CVE-2023-6121)

  - A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two
    threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline
    enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This
    could allow a local unprivileged user to escalate their privileges on the system. (CVE-2023-6546)

  - An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux
    Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
    (CVE-2023-6606)

  - An out-of-bounds read vulnerability was found in smb2_dump_detail in fs/smb/client/smb2ops.c in the Linux
    Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
    (CVE-2023-6610)

  - A null pointer dereference vulnerability was found in nft_dynset_init() in net/netfilter/nft_dynset.c in
    nf_tables in the Linux kernel. This issue may allow a local attacker with CAP_NET_ADMIN user privilege to
    trigger a denial of service. (CVE-2023-6622)

  - A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be
    exploited to achieve local privilege escalation. A perf_event's read_size can overflow, leading to an heap
    out-of-bounds increment or write in perf_read_group(). We recommend upgrading past commit
    382c27f4ed28f803b1f1473ac2d8db0afc795a1b. (CVE-2023-6931)

  - A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve
    local privilege escalation. A race condition can be exploited to cause a timer be mistakenly registered on
    a RCU read locked object which is freed by another thread. We recommend upgrading past commit
    e2b706c691905fe78468c361aaabc719d0a496f1. (CVE-2023-6932)
