Ubuntu Security Notice USN-5140-1
Posted Nov 11, 2021
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5140-1 - It was discovered that the AMD Cryptographic Coprocessor driver in the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could use this to cause a denial of service. It was discovered that an integer overflow could be triggered in the eBPF implementation in the Linux kernel when preallocating objects for stack maps. A privileged local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
