The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4783-1 advisory.

  - An issue was discovered in drivers/bluetooth/hci_ldisc.c in the Linux kernel 6.2. In hci_uart_tty_ioctl,     there is a race condition between HCIUARTSETPROTO and HCIUARTGETPROTO. HCI_UART_PROTO_SET is set before     hu->proto is set. A NULL pointer dereference may occur. (CVE-2023-31083)

  - A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function     dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one     holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a     use-after-free issue, potentially leading to a denial of service or privilege escalation. (CVE-2023-39198)

  - An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker     can trigger a race condition that results in a fill_kobj_path out-of-bounds write. (CVE-2023-45863)

  - An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel     before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)

  - A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf)     component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an     event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory     locations outside of the allocated buffer. We recommend upgrading past commit     32671e3799ca2e4590773fd0e63aaa4229e50c06. (CVE-2023-5717)

  - A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm     scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific     socket configuration, which could allow a local user to crash the system or escalate their privileges on     the system. (CVE-2023-6176)

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