Title: Copy Fail (CVE-2026-31431) Patches Released
Post by: 6Sense on May 07, 2026, 10:33:43 PM

Got an official warning email from my host so thought I'd pass it on to all you linux OS users.

'Our records indicate that you are currently running a Linux instance. On April 29th, 2026, a new high-severity Linux kernel zero-day vulnerability was disclosed, called “Copy Fail” (CVE-2026-31431). This vulnerability enables unauthorized privilege escalation, potentially providing root access.'

Patchs are now available for Alma/Rocky etc so ensure you all upgrade.

This is why everyone needs to keep the base OS up2date.

This CVE related to the base OS Kernel for all Linux OS's out there, not just AlmaLinux.

Thankfully all of AlmaLinux's mirrors had the update ready to download by 2026-05-05

It affected AL8, AL9, and AL10.
