{"cve":"CVE-2022-49433","nvd":{"published":"2025-02-26T07:01:19.763","modified":"2026-06-17T05:18:02.200","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-908"],"references":["https://git.kernel.org/stable/c/05c03dfd09c069c4ffd783b47b2da5dcc9421f2c","https://git.kernel.org/stable/c/288d198f50434f29b4a26a9de4394ae2305ad8af","https://git.kernel.org/stable/c/30eb275e7ed588270ae159cc590a96658e0cfd8f","https://git.kernel.org/stable/c/66090815a24ce14cf51ef5453fc0218fe8a39bc2","https://git.kernel.org/stable/c/addb192000d8819c0b1553453994df9bb54c28db"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49433","score":0.00269,"percentile":0.19176,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
