It also asserts using lockdep\nthat both of those locks are held.  However, the commit I referenced in\nFixes accidentally makes the call to rvt_error_qp in rvt_ruc_loopback no\nlonger covered by r_lock.  This results in the lockdep assertion failing\nand also possibly in a race condition.\n\n## Affected\n\n- `linux_kernel >= 5.0.4, < 5.4.189`\n- `linux_kernel >= 5.5, < 5.10.111`\n- `linux_kernel >= 5.11, < 5.15.34`\n- `linux_kernel >= 5.16, < 5.16.20`\n- `linux_kernel >= 5.17, < 5.17.3`\n- `linux_kernel = 5.18`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 5.17.3`","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
