The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ext2: Fix lost inode updates for IS_SYNC inodes ext2_setsize() and ext2_xattr_set2() had a construct like:
    if (IS_SYNC(inode)) { sync_inode_metadata(inode, 1); } else { mark_inode_dirty(inode); } which leads to     lost inode updates for IS_SYNC inodes because sync_inode_metadata() does anything only if the inode is     already dirty and hence inode updates may be simply lost. Fix the problem by unconditionally marking the     inode dirty and *then* call sync_inode_metadata(). (CVE-2026-89601)

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

The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-9002-1 advisory.

    It was discovered that the io_uring subsystem in the Linux kernel did not properly handle canceled task     work when processing certain wait operations, leading to the operation being performed in the wrong task     context. A local attacker could possibly use this to cause a denial of service (system crash).
    (CVE-2026-81010)
