The remote Ubuntu 24.04 LTS / 26.04 LTS / Pro Realtime 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8726-1 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 A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges.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 Ubuntu 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.

  - In the Linux kernel, the following vulnerability has been resolved: Revert f2fs: remove non-uptodate     folio from the page cache in move_data_block This reverts commit     9609dd704725a40cd63d915f2ab6c44248a44598. The kernel panics are keeping to be reported especially when the     f2fs partition get almost full. By investigation, we find that the reason is one f2fs page got freed to     buddy without being deleted from LRU and the root cause is the race happened in [2] which is enrolled by     this commit. There are 3 race processes in this scenario, please find below for their main activities. The     changed code in move_data_block() lets the GC path evict the tail-end folio from the page cache through     folio_end_dropbehind(). Once folio_unmap_invalidate() removes the folio from mapping->i_pages, the page-     cache references for all pages in the folio are dropped. The folio is then kept alive only by temporary     external references, which allows a later split to operate on a folio whose subpages are no longer     protected by page-cache references. After the page-cache references are gone, split_folio_to_order() can     split the big folio into individual pages and put the resulting subpages back on the LRU. For tail pages     beyond EOF, split removes them from the page cache and drops their page-cache references. A tail page can     then remain on the LRU with PG_lru set while holding only the split caller's temporary reference. When     free_folio_and_swap_cache() drops that final reference, the page enters the final folio_put() release     path. In parallel, folio_isolate_lru() can observe the same tail page with a non-zero refcount and PG_lru     set. It clears PG_lru before taking its own reference. If this races with the final folio_put() from the     split path, __folio_put() sees PG_lru already cleared and skips lruvec_del_folio(). The page is then freed     back to the allocator while its lru links are still present in the LRU list. A later LRU operation on a     neighboring page detects the stale link and reports list corruption. [1] [ 22.486082] list_del corruption.

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

The remote Ubuntu 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8727-1 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)
