In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Fix die ID init and look up bugs In snbep_pci2phy_map_init(), in the nr_node_ids > 8 path, uncore_device_to_die() may return -1 when all CPUs associated with the UBOX device are offline. Remove the WARN_ON_ONCE(die_id == -1) check for two reasons: - The current code breaks out of the loop. This is incorrect because pci_get_device() does not guarantee iteration in domain or bus order, so additional UBOX devices may be skipped during the scan. - Returning -EINVAL is incorrect, since marking offline buses with die_id == -1 is expected and should not be treated as an error. Separately, when NUMA is disabled on a NUMA-capable platform, pcibus_to_node() returns NUMA_NO_NODE, causing uncore_device_to_die() to return -1 for all PCI devices. As a result, spr_update_device_location(), used on Intel SPR and EMR, ignores the corresponding PMON units and does not add them to the RB tree. Fix this by using uncore_pcibus_to_dieid(), which retrieves topology from the UBOX GIDNIDMAP register and works regardless of whether NUMA is enabled in Linux. This requires snbep_pci2phy_map_init() to be added in spr_uncore_pci_init(). Keep uncore_device_to_die() only for the nr_node_ids > 8 case, where NUMA is expected to be enabled.

Tenable has extracted the preceding description block directly from the EulerOS kernel 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.

  - perf/x86/intel/uncore: Fix die ID init and look up bugs In snbep_pci2phy_map_init(), in the nr_node_ids >     8 path, uncore_device_to_die() may return -1 when all CPUs associated with the UBOX device are offline.
    Remove the WARN_ON_ONCE(die_id == -1) check for two reasons: - The current code breaks out of the loop.
    This is incorrect because pci_get_device() does not guarantee iteration in domain or bus order, so     additional UBOX devices may be skipped during the scan. - Returning -EINVAL is incorrect, since marking     offline buses with die_id == -1 is expected and should not be treated as an error. Separately, when NUMA     is disabled on a NUMA-capable platform, pcibus_to_node() returns NUMA_NO_NODE, causing     uncore_device_to_die() to return -1 for all PCI devices. As a result, spr_update_device_location(), used     on Intel SPR and EMR, ignores the corresponding PMON units and does not add them to the RB tree. Fix this     by using uncore_pcibus_to_dieid(), which retrieves topology from the UBOX GIDNIDMAP register and works     regardless of whether NUMA is enabled in Linux. This requires snbep_pci2phy_map_init() to be added in     spr_uncore_pci_init(). Keep uncore_device_to_die() only for the nr_node_ids > 8 case, where NUMA is     expected to be enabled. (CVE-2026-43344)

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