TIMELINE Feb 26 Reserved by Linux Feb 26 Published (CNA: Linux) Aug 4 RESCORED — CVE-2022-49089 (Linux). CVSS 7.8 → 4.7 (NVD).
In the Linux kernel, the following vulnerability has been resolved: IB/rdmavt: add lock to call to rvt_error_qp to prevent a race condition The documentation of the function rvt_error_qp says both r_lock and s_lock need to be held when calling that function. It also asserts using lockdep that both of those locks are held. However, the commit I referenced in Fixes accidentally makes the call to rvt_error_qp in rvt_ruc_loopback no longer covered by r_lock. This results in the lockdep assertion failing and also possibly in a race condition.
