USN-5358-2: Linux kernel vulnerabilities

Published Mar 31, 2022
·
Updated

It was discovered that the network traffic control implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1055) It was discovered that the IPsec implementation in the Linux kernel did not properly allocate enough memory when performing ESP transformations, leading to a heap-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-27666)
