  3. CVE-2022-49606
In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix sleep from invalid context BUG Taking the qos_mutex to process RoCEv2 QP's on netdev events causes a kernel splat. Fix this by removing the handling for RoCEv2 in irdma_cm_teardown_connections that uses the mutex. This handling is only needed for iWARP to avoid having connections established while the link is down or having connections remain functional after the IP address is removed. BUG: sleeping function called from invalid context at kernel/locking/mutex.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/irdma: Arreglar suspensión desde contexto no válido ERROR Tomar qos_mutex para procesar los QP de RoCEv2 en eventos netdev provoca un splat del kernel. Solucione esto eliminando la gestión de RoCEv2 en irdma_cm_teardown_connections que usa el mutex. Esta gestión solo es necesario para que iWARP evite que se establezcan conexiones mientras el enlace está inactivo o que las conexiones permanezcan funcionales después de que se elimine la dirección IP. ERROR: función de suspensión llamada desde un contexto no válido en kernel/locking/mutex.
