A use-after-free flaw was found in PackageKitd. In some conditions, the order of cleanup mechanics for a transaction could be impacted. As a result, some memory access could occur on memory regions that were previously freed. Once freed, a memory region can be reused for other allocations and any previously stored data in this memory region is considered lost.
A flaw was found in nbdkit due to to improperly caching plaintext state across the STARTTLS encryption boundary. A MitM attacker could use this flaw to inject a plaintext NBDOPTSTRUCTUREDREPLY before proxying everything else a client sends to the server, potentially leading the client to terminate the NBD session. The highest threat from this vulnerability is to system availability.
A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdmacm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms.

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: InnoDB). Supported versions that are affected are 8.0.16 and prior. Difficult to exploit vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of MySQL Server accessible data.

An unspecified vulnerability in Java SE related to the Networking component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
A denial of service vulnerability was discovered in nbdkit 1.12.7, 1.14.1 and 1.15.1. An attacker could connect to the nbdkit service and cause it to perform a large amount of work in initializing backend plugins, by simply opening a connection to the service. This vulnerability could cause resource consumption and degradation of service in nbdkit, depending on the plugins configured on the server-side.
Virt-install(1) utility used to provision new virtual machines has introduced an option '--unattended' to create VMs without user interaction. This option accepts guest VM password as command line arguments. Thus leaking them to others users on the system via process listing. It was introduced recently in the virt-manager v2.2.0 release.

The Libreswan Project has found a vulnerability in the processing of IKEv1 informational exchange packets which are encrypted and integrity protected using the established IKE SA encryption and integrity keys, but as a receiver, the integrity check value was not verified.

A flaw was found in the kernel's audit by access permission feature which would not record openbyhandleat syscalls.
This does not mean that a user is granted access to resources that they would not be able to. This means that the audit log trail would not contain the log events of access.
A null pointer dereference issue was found in the IDE disk emulator of QEMU. It could occur while cancelling an i/o operation via idecanceldmasync() routine, if a block drive pointer is null. A guest may use this flaw to crash the QEMU process on the host resulting in DoS scenario.
Upstream patch: --------------- -> https://lists.nongnu.org/archive/html/qemu-devel/2020-09/msg01568.html
An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service.
