The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013823 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    ubifs: ubifs_releasepage: Remove ubifs_assert(0) to valid this process

    There are two states for ubifs writing pages:
    1. Dirty, Private     2. Not Dirty, Not Private

    The normal process cannot go to ubifs_releasepage() which means there     exists pages being private but not dirty. Reproducer[1] shows that it     could occur (which maybe related to [2]) with following process:

         PA                     PB                    PC     lock(page)[PA]     ubifs_write_end       attach_page_private         // set Private
      __set_page_dirty_nobuffers  // set Dirty     unlock(page)

    write_cache_pages[PA]       lock(page)       clear_page_dirty_for_io(page) // clear Dirty       ubifs_writepage

                            do_truncation[PB]                               truncate_setsize                                 i_size_write(inode, newsize) // newsize = 0

        i_size = i_size_read(inode) // i_size = 0         end_index = i_size >> PAGE_SHIFT         if (page->index > end_index)           goto out // jump     out:
    unlock(page)   // Private, Not Dirty

                                                    generic_fadvise[PC]                                                       lock(page)                                                       invalidate_inode_page                                                         try_to_release_page                                                           ubifs_releasepage                                                             ubifs_assert(c, 0)                                                             // bad assertion!                                                       unlock(page)                               truncate_pagecache[PB]
