CVE-2024-42301 Information

Description

In the Linux kernel the following vulnerability has been resolved:

dev/parport: fix the array out-of-bounds risk

Fixed array out-of-bounds issues caused by sprintf by replacing it with snprintf for safer data copying ensuring the destination buffer is not overflowed.

Below is the stack trace I encountered during the actual issue:
