Threats tagged 'ghsa-wrg6-48wc-j3w4'

A vulnerability in the Linux kernel's net/sched cls_api subsystem was resolved to prevent excessive CPU usage and system hangs caused by repeated RTM_GETCHAIN requests on netlink sockets without reading responses. The issue arises when tc_ctl_chain() replays RTM_GETCHAIN requests unnecessarily, leading to CPU hogging and a hung task state. The fix restricts replay logic to RTM_NEWCHAIN requests only. This vulnerability affects specific versions of the linux-hwe-edge kernel.
