Last modified

CVE-2020-8938 is a low-severity vulnerability rated 3.3/10 on the CVSS scale. An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make a host call to FromkLinuxSockAddr with attacker controlled content and size of klinux_addr which allows an attacker to write memory values from within the enclave. We recommend upgrading past commit a37fb6a0e7daf30134dbbf357c9a518a1026aa02. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
