RunC allowed additional container processes via 'runc exec' to be ptraced by the pid 1 of the container. This allows the main processes of the container, if running as root, to gain access to file-descriptors of these new processes during the initialization and can lead to container escapes or modification of runC state before the process is fully placed inside the container.

Exploit prediction (EPSS)

0.41% probability of exploitation in the next 30 days, higher than 36% of all scored CVEs.
