{"id":"CVE-2022-50583","summary":"md/raid0, raid10: Don't set discard sectors for request queue","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid0, raid10: Don't set discard sectors for request queue\n\nIt should use disk_stack_limits to get a proper max_discard_sectors\nrather than setting a value by stack drivers.\n\nAnd there is a bug. If all member disks are rotational devices,\nraid0/raid10 set max_discard_sectors. So the member devices are\nnot ssd/nvme, but raid0/raid10 export the wrong value. It reports\nwarning messages in function __blkdev_issue_discard when mkfs.xfs\nlike this:\n\n[ 4616.022599] ------------[ cut here ]------------\n[ 4616.027779] WARNING: CPU: 4 PID: 99634 at block/blk-lib.c:50 __blkdev_issue_discard+0x16a/0x1a0\n[ 4616.140663] RIP: 0010:__blkdev_issue_discard+0x16a/0x1a0\n[ 4616.146601] Code: 24 4c 89 20 31 c0 e9 fe fe ff ff c1 e8 09 8d 48 ff 4c 89 f0 4c 09 e8 48 85 c1 0f 84 55 ff ff ff b8 ea ff ff ff e9 df fe ff ff \u003c0f\u003e 0b 48 8d 74 24 08 e8 ea d6 00 00 48 c7 c6 20 1e 89 ab 48 c7 c7\n[ 4616.167567] RSP: 0018:ffffaab88cbffca8 EFLAGS: 00010246\n[ 4616.173406] RAX: ffff9ba1f9e44678 RBX: 0000000000000000 RCX: ffff9ba1c9792080\n[ 4616.181376] RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff9ba1c9792080\n[ 4616.189345] RBP: 0000000000000cc0 R08: ffffaab88cbffd10 R09: 0000000000000000\n[ 4616.197317] R10: 0000000000000012 R11: 0000000000000000 R12: 0000000000000000\n[ 4616.205288] R13: 0000000000400000 R14: 0000000000000cc0 R15: ffff9ba1c9792080\n[ 4616.213259] FS:  00007f9a5534e980(0000) GS:ffff9ba1b7c80000(0000) knlGS:0000000000000000\n[ 4616.222298] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 4616.228719] CR2: 000055a390a4c518 CR3: 0000000123e40006 CR4: 00000000001706e0\n[ 4616.236689] Call Trace:\n[ 4616.239428]  blkdev_issue_discard+0x52/0xb0\n[ 4616.244108]  blkdev_common_ioctl+0x43c/0xa00\n[ 4616.248883]  blkdev_ioctl+0x116/0x280\n[ 4616.252977]  __x64_sys_ioctl+0x8a/0xc0\n[ 4616.257163]  do_syscall_64+0x5c/0x90\n[ 4616.261164]  ? handle_mm_fault+0xc5/0x2a0\n[ 4616.265652]  ? do_user_addr_fault+0x1d8/0x690\n[ 4616.270527]  ? do_syscall_64+0x69/0x90\n[ 4616.274717]  ? exc_page_fault+0x62/0x150\n[ 4616.279097]  entry_SYSCALL_64_after_hwframe+0x63/0xcd\n[ 4616.284748] RIP: 0033:0x7f9a55398c6b","modified":"2026-04-02T08:28:38.780423Z","published":"2025-12-08T01:12:18.853Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50583.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/27e5d61a8e6919b5c0c6f473703ffea2acba862a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8e1a2279ca2b0485cc379a153d02a9793f74a48f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e80bef070699d2e791badefccb1ddabd6998d468"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50583.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50583"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"70200574cc229f6ba038259e8142af2aa09e6976"},{"fixed":"e80bef070699d2e791badefccb1ddabd6998d468"},{"fixed":"27e5d61a8e6919b5c0c6f473703ffea2acba862a"},{"fixed":"8e1a2279ca2b0485cc379a153d02a9793f74a48f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50583.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.19.0"},{"fixed":"6.0.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50583.json"}}],"schema_version":"1.7.5"}
