Ubuntu Security Notice 6951-1 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6950-1 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6949-1 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Researchers at Aqua Security discovered the "Shadow Resource" attack vector and the "Bucket Monopoly" problem, where threat actors can guess the name of S3 buckets based on their public account IDs.

Ubuntu Security Notice 6924-2 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6923-2 - Benedict Schlüter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde discovered that an untrusted hypervisor could inject malicious #VC interrupts and compromise the security guarantees of AMD SEV-SNP. This flaw is known as WeSee. A local attacker in control of the hypervisor could use this to expose sensitive information or possibly execute arbitrary code in the trusted execution environment. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

As more people work remotely, IT departments must manage devices distributed over different cities and countries relying on VPNs and remote monitoring and management (RMM) tools for system administration.  However, like any new technology, RMM tools can also be used maliciously. Threat actors can establish connections to a victim's device and run commands, exfiltrate data, and stay

Ubuntu Security Notice 6926-1 - 黄思聪 discovered that the NFC Controller Interface implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service.
