Last modified
CVE-2021-40526 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. Incorrect calculation of buffer size vulnerability in Peleton TTR01 up to and including PTV55G allows a remote attacker to trigger a Denial of Service attack through the GymKit daemon process by exploiting a heap overflow in the network server handling the Apple GymKit communication. This can lead to an Apple MFI device not being able to authenticate with the Peleton Bike. EPSS estimates a 0.95% chance of exploitation in the next 30 days.
