Back-to-back kernel vulnerabilities in Linux has defenders scrambling to apply defenses in the age of quick turnaround time for hackers to exploit nascent flaws.<\/p>\n

“Dirty Frag” and “Copy Fail” kernel privilege escalation vulnerabilities became public knowledge within two weeks of each other (see: ‘Dirty Frag’ Gives Root on Linux Distros).<\/p>\n

Microsoft said in a Friday blog that it has found limited in-the-wild activity associated with either one of the vulnerabilities. <\/p>\n

One Linux maintainer is floating the possibility of integrating a “kill switch” feature that would allow admins to temporarily shut down vulnerable kernel functions while patches are developed. <\/p>\n

“For most users, the cost of ‘this socket family stops working for the day’ is much smaller than the cost of running a known vulnerable kernel until the fix land,” Linux stable kernel co-maintainer and Nvidia engineer Sasha Levin wrote in an email.<\/p>\n

The proposal is not official and it’s only meant to buy time between kernel vulnerability discoveries and patch releases.<\/p>\n

“As we’ve seen with the discovery of ‘Dirty Frag’ fresh on the heels of ‘Copy Fail,’ AI-assisted vulnerability discovery is rapidly accelerating the identification of new vulnerabilities, a trend that is only going to continue as these models continue to become more powerful,” said Scott Caveza, senior staff research…<\/p>\n
