Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the drainExecSyncIO function in internal/cri/server/containerexecsync.go, pkg/cri/server/containerexecsync.go, and pkg/cri/sbserver/containerexecsync.go. An attacker can cause...

GHSA-7JXH-36Q5-GCQV containerd: CRI ExecSync Goroutine Leak Leads to Node-Level Denial of Service

Impact A bug in containerd's CRI ExecSync implementation allows exec probes and lifecycle hooks with background child processes to keep containerd's stdio-drain goroutines indefinitely blocked. Because the I/O drain phase lacks a default timeout or context cancellation handling, repeated ExecSync...
