  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: initialise error in xfs_defer_finish_one()\n\nxfs_defer_finish_one() declares error without an initialiser and only\nassigns it inside the loop over dfp-\u003edfp_work.  When that list is empty\nthe loop body never runs, control falls through to the \"Done with the\ndfp, free it\" path, and the function returns an indeterminate value.\n\nAn item-less pending item reaches this through xfs_defer_add_barrier(),\nwhich xfs_reap_ag_blocks() uses on any CONFIG_XFS_ONLINE_REPAIR kernel.\nxfs_defer_finish_noroll() treats any non-EAGAIN return as fatal, so a\nnon-zero stack value turns a successful barrier into a\nSHUTDOWN_CORRUPT_INCORE in the middle of a repair.  Zero is the correct\nresult: reaching the free path means the item loop drained without a\nnon-zero error.",
