network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further processing to nevertheless be freed.

Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm, dom0 is using an rbtree to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the related lock held, resulting in a small race window, which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0, e.g. by causing crashes or the inability to perform further mappings of other guests' memory pages.

NULL Pointer Dereference allows attackers to cause a denial of service (or application crash). This only applies when lxml is used together with libxml2 2.9.10 through 2.9.14. libxml2 2.9.9 and earlier are not affected. It allows triggering crashes through forged input data, given a vulnerable code sequence in the application. The vulnerability is caused by the iterwalk function (also used by the canonicalize function). Such code shouldn't be in wide-spread use, given that parsing + iterwalk would usually be replaced with the more efficient iterparse function. However, an XML converter that serialises to C14N would also be vulnerable, for example, and there are legitimate use cases for this code sequence. If untrusted input is received (also remotely) and processed via iterwalk function, a crash can be triggered.

Google on Monday shipped security updates to address a high-severity zero-day vulnerability in its Chrome web browser that it said is being exploited in the wild. The shortcoming, tracked as CVE-2022-2294, relates to a heap overflow flaw in the WebRTC component that provides real-time audio and video communication capabilities in browsers without the need to install plugins or download native

Zoho ManageEngine ADSelfService Plus before 6203 allows a denial of service (application restart) via a crafted payload to the Mobile App Deployment API.

Ubuntu Security Notice 5500-1 - Eric Biederman discovered that the cgroup process migration implementation in the Linux kernel did not perform permission checks correctly in some situations. A local attacker could possibly use this to gain administrative privileges. Lin Ma discovered that the NFC Controller Interface implementation in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5493-2 - It was discovered that the 8 Devices USB2CAN interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service.

Improper input validation vulnerability in Space of Cybozu Garoon 4.0.0 to 5.5.1 allows a remote authenticated attacker to repeatedly display errors in certain functions and cause a denial-of-service (DoS).

Authentication bypass by capture-replay vulnerability exists in Machine automation controller NX7 series all models V1.28 and earlier, Machine automation controller NX1 series all models V1.48 and earlier, and Machine automation controller NJ series all models V 1.48 and earlier, which may allow an adjacent attacker who can analyze the communication between the controller and the specific software used by OMRON internally to cause a denial-of-service (DoS) condition or execute a malicious program.
