Issues addressed include buffer overflow, bypass, denial of service, information leakage, memory leak, null pointer, out of bounds access, out of bounds read, out of bounds write, privilege escalation, and use-after-free vulnerabilities.
8423a084d291f0fd31e09d495d97d8ba57cffbac6ffa4d7817e03bc88c69f331Ubuntu Security Notice 4225-2 - USN-4225-1 fixed vulnerabilities in the Linux kernel for Ubuntu 19.10. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 19.10 for Ubuntu 18.04 LTS. It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
