What the vulnerability does

01Description

In Eclipse ThreadX before version 6.4.3, an attacker can cause a denial of service (crash) by providing a pointer to a reserved or unmapped memory region. Vulnerable system calls had a check of pointers, but that check wasn't verifying whether the pointer is outside the module memory region.
