A flaw was found in the Linux kernel that allows for local privilege escalation:
https://access.redhat.com/security/cve/cve-2026-31431
Updated kernel packages should be coming soon to resolve this issue.
If you can't wait until updated kernels are released and need to apply a temporary mitigation, you can run the following command and then reboot:
sudo grubby --update-kernel=ALL --args="initcall_blacklist=algif_aead_init"
After updated kernels are released, that temporary mitigation can be reverted by running the following command and then rebooting:
sudo grubby --update-kernel=ALL --remove-args="initcall_blacklist=algif_aead_init"
