DEBIAN-CVE-2019-13233
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 modifyldt and a BR exception for an MPX bounds violation...
FreeBSD Kernel amd64_set_ldt Heap Overflow Vulnerability
FreeBSD is a UNIX operating system. An integer signature error in the amd64setldt function in the kernel code of versions prior to FreeBSD 10.2-RELENG can lead to a kernel heap overflow, which can cause a system crash in a local attacker...
kernel: x86: espfix(64) bypass via set_thread_area and CLONE_SETTLS
It was found that the espfix functionality could be bypassed by installing a 16-bit RW data segment into GDT instead of LDT which espfix checks, and using that segment on the stack. A local, unprivileged user could potentially use this flaw to leak kernel stack addresses...
