In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix FSCTL permission bypass by adding a permission check for FSCTL_SET_SPARSE FSCTL_SET_SPARSE in fsctl_set_sparse() modifies the file's sparse attribute and saves it through xattr without any permission checks. This exposes two issues: 1) A client on a read-only share can change the sparse attribute on files it opened, even though the share is read-only. Other FSCTL write operations already check test_tree_conn_flag(work->tcon, KSMBD_TREE_CONN_FLAG_WRITABLE), but FSCTL_SET_SPARSE does not. 2) Even on writable shares, clients without FILE_WRITE_DATA or FILE_WRITE_ATTRIBUTES access should not modify the sparse attribute. Similar handle-level checks exist in other functions but are missing here. Add both share-level writable check and per-handle access check. Use goto out on error to avoid leaking file references.

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 remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8906-1 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 A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges.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.

  - ksmbd: fix FSCTL permission bypass by adding a permission check for FSCTL_SET_SPARSE FSCTL_SET_SPARSE in     fsctl_set_sparse() modifies the file's sparse attribute and saves it through xattr without any permission     checks. This exposes two issues: 1) A client on a read-only share can change the sparse attribute on files     it opened, even though the share is read-only. Other FSCTL write operations already check     test_tree_conn_flag(work->tcon, KSMBD_TREE_CONN_FLAG_WRITABLE), but FSCTL_SET_SPARSE does not. 2) Even on     writable shares, clients without FILE_WRITE_DATA or FILE_WRITE_ATTRIBUTES access should not modify the     sparse attribute. Similar handle-level checks exist in other functions but are missing here. Add both     share-level writable check and per-handle access check. Use goto out on error to avoid leaking file     references. (CVE-2026-52944)

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