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:
