In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_event: Ignore multiple conn complete events When one of the three connection complete events is received multiple times for the same handle, the device is registered multiple times which leads to memory corruptions. Therefore, consequent events for a single connection are ignored. The conn->state can hold different values, therefore HCI_CONN_HANDLE_UNSET is introduced to identify new connections. To make sure the events do not contain this or another invalid handle HCI_CONN_HANDLE_MAX and checks are introduced. Buglink: https://bugzilla.kernel.org/show_bug.cgi?id=215497

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:02846-1 advisory.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Bluetooth: hci_event: Ignore multiple conn complete events When one of the three connection complete     events is received multiple times for the same handle, the device is registered multiple times which leads     to memory corruptions. Therefore, consequent events for a single connection are ignored. The conn->state     can hold different values, therefore HCI_CONN_HANDLE_UNSET is introduced to identify new connections. To     make sure the events do not contain this or another invalid handle HCI_CONN_HANDLE_MAX and checks are     introduced. Buglink: https://bugzilla.kernel.org/show_bug.cgi?id=215497 (CVE-2022-49138)

Note that Nessus relies on the presence of the package as reported by the vendor.
