Description

A flaw was found in the Linux kernel's Intelligent Platform Management Bus (IPMB) component. The IPMB event handler fails to initialize read bytes, which can lead to an uninitialized value being returned during an I2C (Inter-Integrated Circuit) read operation. This could allow a local attacker to obtain sensitive information from the system.

Mitigation

No mitigation is specified in collected source.
