In the Linux kernel, the following vulnerability has been resolved: iommu/sva: invalidate stale IOTLB entries for kernel address space Introduce a new IOMMU interface to flush IOTLB paging cache entries for the CPU kernel address space. This interface is invoked from the x86 architecture code that manages combined user and kernel page tables, specifically before any kernel page table page is freed and reused. This addresses the main issue with vfree() which is a common occurrence and can be triggered by unprivileged users. While this resolves the primary problem, it doesn't address some extremely rare case related to memory unplug of memory that was present as reserved memory at boot, which cannot be triggered by unprivileged users. The discussion can be found at the link below. Enable SVA on x86 architecture since the IOMMU can now receive notification to flush the paging cache before freeing the CPU kernel page table pages.

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 A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges.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

    netdevsim: fix a race issue related to the operation on bpf_bound_progs list(CVE-2026-23126)

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.

  - iommu/sva: invalidate stale IOTLB entries for kernel address space Introduce a new IOMMU interface to     flush IOTLB paging cache entries for the CPU kernel address space. This interface is invoked from the x86     architecture code that manages combined user and kernel page tables, specifically before any kernel page     table page is freed and reused. This addresses the main issue with vfree() which is a common occurrence     and can be triggered by unprivileged users. While this resolves the primary problem, it doesn't address     some extremely rare case related to memory unplug of memory that was present as reserved memory at boot,     which cannot be triggered by unprivileged users. The discussion can be found at the link below. Enable SVA     on x86 architecture since the IOMMU can now receive notification to flush the paging cache before freeing     the CPU kernel page table pages. (CVE-2025-71202)

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