CVE-2023-53584 at MITRE

Description

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]

Then we may get following assertion failed:
UBIFS error (ubi0:0 pid 1683): ubifs_assert_failed [ubifs]:
UBIFS assert failed: 0, in fs/ubifs/file.c:1513
UBIFS warning (ubi0:0 pid 1683): ubifs_ro_mode [ubifs]:
