The remote Ubuntu 24.04 LTS / Pro Realtime 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8781-1 advisory.

    It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB)     invalidation before memory writes made through the invalidated translation were globally observed. A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges. (CVE-2025-10263)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

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.

  - net/mlx5e: RX, Fix XDP multi-buf frag counting for legacy RQ XDP multi-buf programs can modify the layout     of the XDP buffer when the program calls bpf_xdp_pull_data() or bpf_xdp_adjust_tail(). The referenced     commit in the fixes tag corrected the assumption in the mlx5 driver that the XDP buffer layout doesn't     change during a program execution. However, this fix introduced another issue: the dropped fragments still     need to be counted on the driver side to avoid page fragment reference counting issues. Such issue can be     observed with the test_xdp_native_adjst_tail_shrnk_data selftest when using a payload of 3600 and     shrinking by 256 bytes (an upcoming selftest patch): the last fragment gets released by the XDP code but     doesn't get tracked by the driver. This results in a negative pp_ref_count during page release and the     following splat: WARNING: include/net/page_pool/helpers.h:297 at     mlx5e_page_release_fragmented.isra.0+0x4a/0x50 [mlx5_core], CPU#12: ip/3137 Modules linked in: [...] CPU:

    __sys_sendmsg+0x5f/0xb0 [...] do_syscall_64+0x57/0xc50 This patch fixes the issue by doing page frag     counting on all the original XDP buffer fragments for all relevant XDP actions (XDP_TX , XDP_REDIRECT and     XDP_PASS). This is basically reverting to the original counting before the commit in the fixes tag. As     frag_page is still pointing to the original tail, the nr_frags parameter to xdp_update_skb_frags_info()     needs to be calculated in a different way to reflect the new nr_frags. (CVE-2026-43464)

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