Linux - Use-After-Free via race Between modify_ldt() and #BR Exception Exploit

/ When a BR exception is raised because of an MPX bounds violation, Linux parses the faulting instruction and computes the linear address of its memory operand. If the userspace instruction is in 32-bit code, this involves looking up the correct segment descriptor and adding the segment offset to...
