CVE-2023-52566: nilfs2: fix potential use after free in nilfs_gccache_submit_read_data()

Published Mar 2, 2024

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

nilfs2: fix potential use after free in nilfsgccachesubmitreaddata()

In nilfsgccachesubmitreaddata(), brelse(bh) is called to drop the reference count of bh when the call to nilfsdattranslate() fails. If the reference count hits 0 and its owner page gets unlocked, bh may be freed. However, bh->bpage is dereferenced to put the page after that, which may result in a use-after-free bug. This patch moves the release operation after unlocking and putting the page.

NOTE: The function in question is only called in GC, and in combination with current userland tools, address translation using DAT does not occur in that function, so the code path that causes this issue will not be executed. However, it is possible to run that code path by intentionally modifying the userland GC library or by calling the GC ioctl directly.
