      <title>CVE-2021-20194</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2021-20194</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; kernel&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>
