Update: It appears that we mischaracterized the conclusions in our title and our summary on this story. Greg KH was referring only to the ELF vulnerability in this story. Whether we were deliberately mislead by the submitter of this story or not, we regret the error.
The original story: According to “Greg KH,” co-maintainer of the 2.6.x.y series of important stability and security fixes, the Linux kernel does not suffer from the much-hyped hyper threading vulnerability that affected the BSDs: ” The main reason there have not been any updates, is that there really isn’t a problem for the 2.6 kernel. The original author has admited this finally, no one was ever able to reproduce it on a 2.6 kernel. The only reason I released a kernel update, was at the time, we thought there was an off-chance that there was a problem. However in further testing, it has not
been the case.” This confirms Linus’s earler assertion.
