cmd: gpt: Fix freeing gpt_pte in gpt_verify()
In case when either gpt_verify_headers() or gpt_verify_partitions() fails, the memory allocated for gpt_pte will be freed in those functions internally, but gpt_pte will still contain non-NULL dangling pointer. The attempt to free it in those cases in gpt_verify() leads to "use after free" error, which leads to a "Synchronous abort" exception. This issue was found by running the next command on the device with incorrect partition table: => gpt verify mmc 0 $partitions which results to: No partition list provided - only basic check "Synchronous Abort" handler, esr 0x96000021, far 0xba247bff .... Fix the issue by only freeing gpt_pte if none of those functions failed. Fixes: bbb9ffac6066 ("gpt: command: Extend gpt command to support GPT table verification") Signed-off-by: Sam Protsenko <semen.protsenko@linaro.org>
