CVE-2024-50074 Information

Description

In the Linux kernel the following vulnerability has been resolved:

parport: Proper fix for array out-of-bounds access

The recent fix for array out-of-bounds accesses replaced sprintf() calls blindly with snprintf(). However since snprintf() returns the would-be-printed size not the actually output size the length calculation can still go over the given limit.

Use scnprintf() instead of snprintf() which returns the actually output letters for addressing the potential out-of-bounds access properly.
