linux is vulnerable to privilege escalation. The vulnerability exists if kernel compiled with config params CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y, and CONFIG_HARDENED_USERCOPY not set, and BPF hook to getsockopt is registered. During the execution of BPF, the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap overflow.
