Nothing depends on this version.
Known vulnerabilities and defects
- Meltdown (CVE-2017-5754): Rogue data cache load: user code can read kernel memory through speculative execution.
- Spectre variant 1 (bounds check bypass) (CVE-2017-5753): Mistrained conditional branches speculatively read out-of-bounds data. Mitigated in software only; every speculative out-of-order core is affected.
Matched by codename; individual steppings may differ.
