A flaw was found in the Linux kernel’s implementation of MIDI, where an attacker with a local account and the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to this specific memory while freed and before use causes the flow of execution to change and possibly allow for memory corruption or privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries platform) a root like local user could use this flaw to further increase their privileges to that of a running kernel.

A flaw was found in the Linux kernel where an unprivileged console user can crash kernel via a nouveau ioctl.

A privilege escalation flaw was found in OpenShift builder. During build time, credentials outside the build context are automatically mounted into the container image under construction. An OpenShift user, able to execute code during build time inside this container can re-use the credentials to overwrite arbitrary container images in internal registries and/or escalate their privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A use-after-free vulnerability was found in the Go GPGME wrapper library, github.com/proglottis/gpgme. An attacker could use this flaw to crash or cause potential code execution in Go applications that use this library, under certain conditions, during GPG signature verification.
