It was found that 3scale's APIdocs does not validate the access token in the case of invalid token; instead it uses session auth. This conceivably bypasses access controls and permits viewing unauthorized information.

It was found that all versions of 3Scale developer portal lacked brute force protections. An attacker could use this gap to bypass login controls, and access privileged information, or possibly conduct further attacks.

A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmapnetlblimport' routine. While processing the CIPSO restricted bitmap tag in the 'cipsov4parsetagrbm' 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.
