CVE-2015-2672 (GCVE-0-2015-2672)

Vulnerability from cvelistv5 – Published: 2016-05-02 10:00 – Updated: 2024-08-06 05:24

Summary

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.

Severity

No CVSS data available.
