This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol&#39;s category bitmap into the SELinux extensible bitmap via the&#39; ebitmap_netlbl_import&#39; routine. While processing the CIPSO restricted bitmap tag in the &#39;cipso_v4_parsetag_rbm&#39; routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service.</p> <p><strong>Affected:</strong> Red Hat Kernel</p> <p>A NULL pointer dereference flaw was found in the Linux kernel&#39;s SELinux subsystem in versions before 5.7.
