      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nfuse: re-lock request before returning from fuse_ref_folio()\n\nfuse_ref_folio() unlocks the request but does not re-lock it before\nreturning. fuse_chan_abort() can end the request and the async end\ncallback (eg fuse_writepage_free()) can free the args while the\nsubsequent copy chain logic after fuse_ref_folio() accesses them,\nleading to use-after-free issues.\n\nFix this by locking the request in fuse_ref_folio() before returning.",
