      "title": "fuse: re-lock request before replacing page cache folio",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nfuse: re-lock request before replacing page cache folio\n\nfuse_try_move_folio() unlocks the request on entry but does not\nre-lock it on the success path. This means fuse_chan_abort() can end the\nrequest and free the fuse_io_args (eg fuse_readpages_end()) while the\nsubsequent copy chain logic after fuse_try_move_folio() accesses the\nfuse_io_args, leading to use-after-free issues.\n\nFix this by calling lock_request() before replace_page_cache_folio().\nThis ensures the request is locked on the success path which will\nprevent the fuse_io_args from being freed while the later copying logic\nruns, and also ensures that the ap->folios[i]->mapping is never null\nsince ap->folios[i] will always point to the newfolio after\nreplace_page_cache_folio().",
