CVE-2024-50074 is a high-severity vulnerability in the Linux kernel's parport subsystem involving an array out-of-bounds access. The initial fix replaced unsafe sprintf() calls with snprintf(), but due to snprintf() returning the would-be output size rather than the actual output size, the length calculation could still exceed buffer limits. The proper fix uses scnprintf(), which returns the actual number of characters output, effectively preventing the out-of-bounds access.
