1 | 0[$] Strengthening user-space Spectre v2 protection null/LWN/0000764209 70\r |

| 4 | i The Spectre variant 2 vulnerability allows the speculative\r | |
| 5 | i execution of incorrect (in an attacker-controllable way)\r | |
| 6 | i indirect branch predictions, resulting in the ability to\r | |
| 7 | i exfiltrate information via side channels. The kernel has been\r | |
| 8 | i reasonably well protected against this variant since shortly\r | |
| 9 | i after its disclosure in January. It is, however, possible for\r | |
| 10 | i user-space processes to use Spectre v2 to attack each other;\r | |
| 11 | i thus far, the mainline kernel has offered relatively little\r | |
| e818d449 NR |
12 | i protection against such attacks. A recent [1]proposal from\r |
| 13 | i Jiri Kosina may change that situation, but there are still\r | |
| 14 | i some disagreements around the details.\r | |
