Linux Kernel Flaw: The “Double Trouble” Bug That Elevates Privileges – Patch Now!
The U.S. Cybersecurity & Infrastructure Security Agency (CISA) has flagged CVE-2024-1086, a high-severity Linux kernel privilege escalation flaw, in its Known Exploited Vulnerabilities catalog. This bug, lurking since 2014, could let attackers gain root access. Federal agencies have until June 20, 2024, to patch it…
Hot Take:
Looks like Linux got itself into a bit of a pickle! With a kernel flaw from 2014 finally patched in 2024, it’s like a decade-long “Where’s Waldo?” for bugs. And Red Hat, I hope you enjoyed your nap because the hackers sure did!
Key Points:
- CISA adds two new vulnerabilities to its KEV catalog, including a Linux kernel privilege elevation flaw (CVE-2024-1086).
- The flaw has been around since 2014, involving a use-after-free issue in the netfilter: nf_tables component.
- The vulnerability allows local attackers to escalate privileges, potentially gaining root access.
- Fixes were backported to multiple stable kernel versions, but Red Hat delayed patching until March 2024.
- Admins are advised to blocklist ‘nf_tables’ and restrict access to user namespaces if updating isn’t possible.
