Linux Erroneously Thinks Intel Bartlett Lake CPUs Run At 7GHz

With Intel's recently-launched Bartlett Lake P-core-only processors intended for the embedded market, there is a rather surprising oversight under Linux: the Intel P-State driver reporting a 7.0+ GHz clock speed. While many would yearn for a 7GHz CPU, the Core 9 273PE where this issue was discovered in reality can only boost up to 5.7GHz for its maximum turbo frequency...

Dirty Frag: a zero-day universal Linux LPE

Hyunwoo Kim has announced the Dirty Frag security flaw, a local-privilege-escalation (LPE) vulnerability similar to the recently disclosed Copy Fail flaw: Because the embargo has now been broken, no patches or CVEs exist for these vulnerabilities. After consultation with the linux-distros@vs.openwall.org maintainers, and at the maintainers' request, I am publicly releasing this Dirty Frag document. As with the previous Copy Fail vulnerability, Dirty Frag likewise allows immediate root privilege escalation on all major distributions. Kim, who discovered the flaw and had attempted a coordinated disclosure set for May 12, has released the code for an exploit, as well as a example script to remove the vulnerable modules. A full write-up, with the disclosure timeline, is also available. It's unknown at this time whether this is an example of parallel discovery or how the third party was able to disclose it prior to the end of the embargo. We will be following up as more information comes to
