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

  - In the Linux kernel, the following vulnerability has been resolved: erofs: set fileio bio failed in short     read case For file-backed mount, IO requests are handled by vfs_iocb_iter_read(). However, it can be     interrupted by SIGKILL, returning the number of bytes actually copied. Unused folios in bio are     unexpectedly marked as uptodate. vfs_read filemap_read filemap_get_pages filemap_readahead     erofs_fileio_readahead erofs_fileio_rq_submit vfs_iocb_iter_read filemap_read filemap_get_pages <= detect     signal erofs_fileio_ki_complete <= set all folios uptodate This patch addresses this by setting short read     bio with an error directly. (CVE-2026-31514)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1646 advisory.
