The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2401 advisory.

  - A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local     privilege escalation. The io_file_get_fixed function lacks the presence of ctx->uring_lock which can lead     to a Use-After-Free vulnerability due a race condition with fixed files getting unregistered. We recommend     upgrading past commit da24142b1ef9fd5d36b76e36bab328a5b27523e8. (CVE-2023-1872)

  - A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. In     this flaw, a call to btsdio_remove with an unfinished job, may cause a race problem leading to a UAF on     hdev devices. (CVE-2023-1989)

  - A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in     SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal information.
    (CVE-2023-2162)

  - cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

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