In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net: atm: reject out-of-range traffic classes in QoS validation<\/p>\n
Reject ATM traffic classes above ATM_ANYCLASS in check_tp().
\nSO_ATMQOS stores the supplied QoS after check_qos() succeeds, so
\naccepting larger values leaves invalid traffic_class values in
\nvcc->qos.<\/p>\n
That bad state later reaches pvc_info(), which indexes class_name[]
\nwith vcc->qos.{rx,tp}.traffic_class. Values above ATM_ANYCLASS cause
\nan out-of-bounds read when \/proc\/net\/atm\/pvc is read.<\/p>\n
Tighten the existing QoS validation so invalid traffic_class values
\nare rejected at the point where user supplied QoS is accepted.<\/p>\n","protected":false},"excerpt":{"rendered":"
