"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbcache: fix cached_dev.sb_bio use-after-free and crash\n\nIn our production environment, we have received multiple crash reports\nregarding libceph, which have caught our attention:\n\n```\n[6888366.280350] Call Trace:\n[6888366.280452] blk_update_request+0x14e/0x370\n[6888366.280561] blk_mq_end_request+0x1a/0x130\n[6888366.280671] rbd_img_handle_request+0x1a0/0x1b0 [rbd]\n[6888366.280792] rbd_obj_handle_request+0x32/0x40 [rbd]\n[6888366.280903] __complete_request+0x22/0x70 [libceph]\n[6888366.281032] osd_dispatch+0x15e/0xb40 [libceph]\n[6888366.281164] ? inet_recvmsg+0x5b/0xd0\n[6888366.281272] ? ceph_tcp_recvmsg+0x6f/0xa0 [libceph]\n[6888366.281405] ceph_con_process_message+0x79/0x140 [libceph]\n[6888366.281534] ceph_con_v1_try_read+0x5d7/0xf30 [libceph]\n[6888366.281661] ceph_con_workfn+0x329/0x680 [libceph]\n```\n\nAfter analyzing the coredump file, we found that the address of\ndc->sb_bio has been freed. We know that cached_dev is only freed when it\nis stopped.\n\nSince sb_bio is a part of struct cached_dev, rather than an alloc every\ntime. If the device is stopped while writing to the superblock, the\nreleased address will be accessed at endio.\n\nThis patch hopes to wait for sb_write to complete in cached_dev_free.\n\nIt should be noted that we analyzed the cause of the problem, then tell\nall details to the QWEN and adopted the modifications it made."
