In the Linux kernel, the following vulnerability has been resolved: netfs: Fix ceph copy to cache on write-begin At the end of netfsunlockreadfolio() in which folios are marked appropriately for copying to the cache (either with by being marked dirty and having their private data set or by having PGprivate2 set) and then unlocked, the folioqueue struct has the entry pointing to the folio cleared. This presents a problem for netfspgpriv2writetothecache(), which is used to write folios marked with PGprivate2 to the cache as it expects to be able to trawl the folioqueue list thereafter to find the relevant folios, leading to a hang. Fix this by not clearing the folio_queue entry if we're going to do the deprecated copy-to-cache. The clearance will be done instead as the folios are written to the cache. This can be reproduced by starting cachefiles, mounting a ceph filesystem with "-o fsc" and writing to it.
