Multiple CPU issues affect major OSes |
 |
Many technology websites are abuzz this week with news of multiple bugs in Intel processors which can leak critical kernel information to programs running on the operating system. This could potentially leak user credentials or security keys to any malicious program or user on the system. CNXSoft reports, "Many security bugs can be fixed without performance penalty, but according to reports Intel processors have a hardware bug - whose details have not been disclosed yet (embargo) - that seems to affect all operating systems including Windows, Linux, macOS, etc, and the fix may lead to significant performance hits for some tasks." Working around the bug seem to slow down systems by 5% to 30%, depending on the task being monitored. It has been reported that, apart from Intel x86 processors, ARM64 CPUs are also affected. Tom Lendacky, a Linux developer working for AMD, has stated that AMD x86 processors are not affected by one of the bugs, but other, related bugs appear to affect all x86 processors.. Patches for all major operating systems are expected in be released during the month of January 2018. The openSUSE News page has more details on the multiple processor issues. |
