Description
In arch/x86/lib/insn-eval.c in the Linux kernel before 5.1.9, there is a use-after-free for access to an LDT entry because of a race condition between modify_ldt() and a #BR exception for an MPX bounds violation.
A vulnerability was found in the arch/x86/lib/insn-eval.c function in the Linux kernel. An attacker could corrupt the memory due to a flaw in use-after-free access to an LDT entry caused by a race condition between modify_ldt() and a #BR exception for an MPX bounds violation.
