It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux kernel did not properly perform data buffer size validation in some situations. A physically proximate attacker could use this to craft a malicious USB device that when inserted, could cause a denial of service (system crash) or possibly expose sensitive information. Reima Ishii discovered that the nested KVM implementation for Intel x86 processors in the Linux kernel did not properly validate control registers in certain situations. An attacker in a guest VM could use this to cause a denial of service (guest crash). Various other issues were also addressed.

Incorrect permission checks in Jenkins Qualys Web App Scanning Connector Plugin 2.0.10 and earlier allow attackers with global Item/Configure permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

Always-incorrect control flow implementation in Jenkins Gradle Plugin 2.8 may result in credentials not being masked (i.e., replaced with asterisks) in the build log in some circumstances.

A cross-site request forgery (CSRF) vulnerability in Jenkins Bazaar Plugin 1.22 and earlier allows attackers to delete previously created Bazaar SCM tags.

Jenkins Chef Identity Plugin 2.0.3 and earlier does not mask the user.pem key form field, increasing the potential for attackers to observe and capture it.

A cross-site request forgery (CSRF) vulnerability in Jenkins GitLab Authentication Plugin 1.17.1 and earlier allows attackers to trick users into logging in to the attacker's account.

Jenkins 2.415 and earlier, LTS 2.401.2 and earlier does not sanitize or properly encode URLs in build logs when transforming them into hyperlinks, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control build log contents.

Ubuntu Security Notice 6248-1 - It was discovered that the network queuing discipline implementation in the Linux kernel contained a null pointer dereference in some situations. A local attacker could use this to cause a denial of service. It was discovered that a race condition existed in Adreno GPU DRM driver in the Linux kernel, leading to a double-free vulnerability. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6247-1 - David Leadbeater discovered that the netfilter IRC protocol tracking implementation in the Linux Kernel incorrectly handled certain message payloads in some situations. A remote attacker could possibly use this to cause a denial of service or bypass firewall filtering. It was discovered that the IDT 77252 ATM PCI device driver in the Linux kernel did not properly remove any pending timers during device exit, resulting in a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service or execute arbitrary code.

Ubuntu Security Notice 6244-1 - Tavis Ormandy discovered that some AMD processors did not properly handle speculative execution of certain vector register instructions. A local attacker could use this to expose sensitive information.
