Ubuntu Security Notice 6439-1 - It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6443-1 - Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local user could use this to cause a denial of service or possibly execute arbitrary code. Kyle Zeng discovered that the networking stack implementation in the Linux kernel did not properly validate skb object size in certain conditions. An attacker could use this cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6416-3 - It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising speculative execution and branch prediction may allow unauthorised memory reads via a speculative side-channel attack. A local attacker could use this to expose sensitive information, including kernel memory.

TinyLab linux-lab v1.1-rc1 and cloud-labv0.8-rc2, v1.1-rc1 are vulnerable to insecure permissions. The default configuration could cause Container Escape.

Without the proper context, organizations waste time mitigating software flaws that won't likely affect their systems.
