{"id":"CVE-2022-49433","summary":"RDMA/hfi1: Prevent use of lock before it is initialized","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/hfi1: Prevent use of lock before it is initialized\n\nIf there is a failure during probe of hfi1 before the sdma_map_lock is\ninitialized, the call to hfi1_free_devdata() will attempt to use a lock\nthat has not been initialized. If the locking correctness validator is on\nthen an INFO message and stack trace resembling the following may be seen:\n\n  INFO: trying to register non-static key.\n  The code is fine but needs lockdep annotation, or maybe\n  you didn't initialize this object before use?\n  turning off the locking correctness validator.\n  Call Trace:\n  register_lock_class+0x11b/0x880\n  __lock_acquire+0xf3/0x7930\n  lock_acquire+0xff/0x2d0\n  _raw_spin_lock_irq+0x46/0x60\n  sdma_clean+0x42a/0x660 [hfi1]\n  hfi1_free_devdata+0x3a7/0x420 [hfi1]\n  init_one+0x867/0x11a0 [hfi1]\n  pci_device_probe+0x40e/0x8d0\n\nThe use of sdma_map_lock in sdma_clean() is for freeing the sdma_map\nmemory, and sdma_map is not allocated/initialized until after\nsdma_map_lock has been initialized. This code only needs to be run if\nsdma_map is not NULL, and so checking for that condition will avoid trying\nto use the lock before it is initialized.","modified":"2026-04-02T08:27:35.437977Z","published":"2025-02-26T02:12:50.553Z","related":["SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1293-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49433.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/05c03dfd09c069c4ffd783b47b2da5dcc9421f2c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/288d198f50434f29b4a26a9de4394ae2305ad8af"},{"type":"WEB","url":"https://git.kernel.org/stable/c/30eb275e7ed588270ae159cc590a96658e0cfd8f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/66090815a24ce14cf51ef5453fc0218fe8a39bc2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/addb192000d8819c0b1553453994df9bb54c28db"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca55150bff5817af4f857a746ecab9862c23e12a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fc0750e659db7b315bf6348902cc8ca3cdd4b8d8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49433.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49433"},{"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":"7724105686e718ac476a6ad3304fea2fbcfcffde"},{"fixed":"66090815a24ce14cf51ef5453fc0218fe8a39bc2"},{"fixed":"addb192000d8819c0b1553453994df9bb54c28db"},{"fixed":"fc0750e659db7b315bf6348902cc8ca3cdd4b8d8"},{"fixed":"ca55150bff5817af4f857a746ecab9862c23e12a"},{"fixed":"30eb275e7ed588270ae159cc590a96658e0cfd8f"},{"fixed":"288d198f50434f29b4a26a9de4394ae2305ad8af"},{"fixed":"05c03dfd09c069c4ffd783b47b2da5dcc9421f2c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49433.json"}}],"schema_version":"1.7.5"}
