Linux vulnerability ‘Dirty Frag’ affects nearly all distributions

Dirty Frag is a critical Linux kernel flaw that can let local attackers gain root on many major distributions.

The bug affects the IPsec ESP and rxrpc paths, and public exploit code is already available after an embargo leak.

Shared servers, containers, CI systems, and other multi-user Linux environments could be fully compromised if unpatched.

AlmaLinux has released testing kernels and temporary workarounds while broader fixes are being rolled out across distros.
