**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a buffer overflow in the Linux kernel, allowing an attacker to write memory out of bounds. This can be achieved by sending malicious data to the kernel using the ioctl cmd FBIOPUT VSCREENINFO. The exploitation of this issue may allow an attacker to execute arbitrary code. A missing bounds check in the fbcon set font() function of fbcon.c can lead to a possible out of bounds write, resulting in local information disclosure without requiring additional execution privileges. User interaction is not needed for exploitation. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a boundary error when setting a font with malicious data using the ioctl cmd PIO FONT, which can cause the kernel to write memory out of bounds. This can potentially allow an attacker to initiate unlimited writing and execute arbitrary code with elevated privileges. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
