CVE-2022-49089

  3. CVE-2022-49089
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: IB/rdmavt: agregar bloqueo a la llamada a rvt_error_qp para evitar una condición de ejecución La documentación de la función rvt_error_qp dice que tanto r_lock como s_lock deben mantenerse al llamar a esa función. También afirma usando lockdep que ambos bloqueos se mantienen. Sin embargo, el commit a la que hice referencia en Correcciones hace que la llamada a rvt_error_qp en rvt_ruc_loopback ya no esté cubierta por r_lock. Esto da como resultado que la afirmación de lockdep falle y también posiblemente en una condición de ejecución.
