An issue was discovered in OpenStack Nova before 23.2.2, 24.x before 24.1.2, and 25.x before 25.0.2. By creating a neutron port with the direct vnic_type, creating an instance bound to that port, and then changing the vnic_type of the bound port to macvtap, an authenticated user may cause the compute service to fail to restart, resulting in a possible denial of service. Only Nova deployments configured with SR-IOV are affected.

v8n is a javascript validation library. Versions of v8n prior to 1.5.1 were found to have an inefficient regular expression complexity in the `lowercase()` and `uppercase()` regex which could lead to a denial of service attack. In testing of the `lowercase()` function a payload of 'a' + 'a'.repeat(i) + 'A' with 32 leading characters took 29443 ms to execute. The same issue happens with uppercase(). Users are advised to upgrade. There are no known workarounds for this issue.

Ubuntu Security Notice 5544-1 - It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly handle some error conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Felix Fu discovered that the Sun RPC implementation in the Linux kernel did not properly handle socket states, leading to a use-after-free vulnerability. A remote attacker could possibly use this to cause a denial of service or execute arbitrary code.

Gentoo Linux Security Advisory 202207-1 - Multiple vulnerabilities have been discovered in HashiCorp Vault, the worst of which could result in denial of service. Versions less than 1.10.3 are affected.

Ubuntu Security Notice 5543-1 - Yu Zhang and Nanyu Zhong discovered that Net-SNMP incorrectly handled memory operations when processing certain requests. A remote attacker could use this issue to cause Net-SNMP to crash, resulting in a denial of service, or possibly execute arbitrary code.

[node-fetch](https://www.npmjs.com/package/node-fetch) is a light-weight module that brings window.fetch to node.js. Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) in the `isOriginPotentiallyTrustworthy()` function in `referrer.js`, when processing a URL string with alternating letters and periods, such as `'http://' + 'a.a.'.repeat(i) + 'a'`.
