In the Linux kernel, the following vulnerability has been resolved:

mtd: parsers: Fix memory leak in mtd parser tplink safeloader parse()

The function mtd parser tplink safeloader parse() allocates buf via mtd parser tplink safeloader read table(). If the allocation for parts[idx].name fails inside the loop, the code jumps to the err free label without freeing buf, leading to a memory leak.

Fix this by freeing the temporary buffer buf in the err free label.

Compile tested only. Issue found using a prototype static analysis tool and code review.
