CVE-2020-10732
Publication date 12 June 2020
Last updated 9 October 2024
Ubuntu priority
Cvss 3 Severity Score
A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data.
From the Ubuntu Security Team
It was discovered that the elf handling code in the Linux kernel did not initialize memory before using it in certain situations. A local attacker could use this to possibly expose sensitive information (kernel memory).
