In the Linux kernel, the following vulnerability has been resolved: Revert "net/smc: Introduce TCP ULP support" This reverts commit d7cd421da9da2cc7b4d25b8537f66db5c8331c40. As reported by Al Viro, the TCP ULP support for SMC is fundamentally broken. The implementation attempts to convert an active TCP socket into an SMC socket by modifying the underlying `struct file`, dentry, and inode in-place, which violates core VFS invariants that assume these structures are immutable for an open file, creating a risk of use after free errors and general system instability. Given the severity of this design flaw and the fact that cleaner alternatives (e.g., LD_PRELOAD, BPF) exist for legacy application transparency, the correct course of action is to remove this feature entirely.

The Rocky Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-2026_66180 advisory.

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 A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges.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

  - Revert net/smc: Introduce TCP ULP support This reverts commit d7cd421da9da2cc7b4d25b8537f66db5c8331c40.
    As reported by Al Viro, the TCP ULP support for SMC is fundamentally broken. The implementation attempts     to convert an active TCP socket into an SMC socket by modifying the underlying `struct file`, dentry, and     inode in-place, which violates core VFS invariants that assume these structures are immutable for an open     file, creating a risk of use after free errors and general system instability. Given the severity of this     design flaw and the fact that cleaner alternatives (e.g., LD_PRELOAD, BPF) exist for legacy application     transparency, the correct course of action is to remove this feature entirely. (CVE-2026-46330)

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