CVE-2015-2672

kernel: unprivileged denial-of-service due to mis-protected xsave/xrstor instructions

Published May 2, 2016 CVSS 3.0 · 5.5 Medium EPSS < 1% KEV · Not listed
Description
The xsave/xrstor implementation in arch/x86/include/asm/xsave.h in the Linux kernel before 3.19.2 creates certain .altinstr_replacement pointers and consequently does not provide any protection against instruction faulting, which allows local users to cause a denial of service (panic) by triggering a fault, as demonstrated by an unaligned memory operand or a non-canonical address memory operand.
