Ubuntu Security Notice 6878-1 - Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6873-1 - It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6870-1 - It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6868-1 - Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida discovered that the Linux kernel mitigations for the initial Branch History Injection vulnerability were insufficient for Intel processors. A local attacker could potentially use this to expose sensitive information. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6866-1 - It was discovered that the ext4 file system implementation in the Linux kernel did not properly validate data state on write operations. An attacker could use this to construct a malicious ext4 file system image that, when mounted, could cause a denial of service. It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code.

Security researchers have shed more light on the cryptocurrency mining operation conducted by the 8220 Gang by exploiting known security flaws in the Oracle WebLogic Server. "The threat actor employs fileless execution techniques, using DLL reflective and process injection, allowing the malware code to run solely in memory and avoid disk-based detection mechanisms," Trend Micro researchers Ahmed

If you want to know what post-quantum cryptography is or why any one will care, see part 1 of my series.On August 24, 2023 the National Institute of Standards and Technology (NIST) published its first draft of post-quantum algorithms. The technologies behind those algorithms were described in part 2 (hash-based signatures) and part 3 (lattice-based cryptography) of this series.This leads to the question: If NIST already has serviceable post-quantum replacements for the Rivest-Shamir-Adleman (RSA) and Elliptic Curve Cryptography (ECC) algorithms, why would they need any other technology? The an

Ubuntu Security Notice 6819-4 - Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service. Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-bounds read vulnerability. An attacker could use this to possibly cause a denial of service.

Ubuntu Security Notice 6831-1 - It was discovered that the HugeTLB file system component of the Linux Kernel contained a NULL pointer dereference vulnerability. A privileged attacker could possibly use this to to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6819-2 - Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service. Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-bounds read vulnerability. An attacker could use this to possibly cause a denial of service.
