There is a vulnerability in the linux kernel versions higher than 5.2 (if kernel compiled with config params CONFIG_BPF_SYSCALL=y CONFIG_BPF=y CONFIG_CGROUPS=y CONFIG_CGROUP_BPF=y CONFIG_HARDENED_USERCOPY not set and BPF hook to getsockopt is registered). As result of BPF execution the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap overflow (because of non-hardened usercopy). The impact of attack could be deny of service or possibly privileges escalation.
