CVE-2026-45921: Linux

Описание

Оригинално описание

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.
