In the Linux kernel, the following vulnerability has been resolved: netfs: Fix potential for tearing in ->remote_i_size and ->zero_point Fix potential tearing in using ->remote_i_size and ->zero_point by copying i_size_read() and i_size_write() and using the same seqcount as for i_size. We need to make sure that netfslib and the filesystems that use it always hold i_lock whilst updating any of the sizes to prevent i_size_seqcount from getting corrupted.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

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 A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges.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)

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.

  - netfs: Fix potential for tearing in ->remote_i_size and ->zero_point Fix potential tearing in using
    ->remote_i_size and ->zero_point by copying i_size_read() and i_size_write() and using the same seqcount     as for i_size. We need to make sure that netfslib and the filesystems that use it always hold i_lock     whilst updating any of the sizes to prevent i_size_seqcount from getting corrupted. (CVE-2026-64160)

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