CVE-2015-2666 WRITEUP WRITEUP
Linux Kernel < 4.0 - Stack-Based Buffer Overflow in Intel Microcode Header Parsing
Stack-based buffer overflow in the get_matching_model_microcode function in arch/x86/kernel/cpu/microcode/intel_early.c in the Linux kernel before 4.0 allows context-dependent attackers to gain privileges by constructing a crafted microcode header and leveraging root privileges for write access to the initrd.
CVE-2015-2672 WRITEUP MEDIUM WRITEUP
Linux Kernel < 3.19.1 - Denial of Service via xsave/xrstor Instruction Faulting
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.
