Overview

Technical description
In the Linux kernel, the following vulnerability has been resolved:
printk: Fix possible console use-after-free
When emitting a record via legacy printing, it is possible that a handover
to another legacy printing context occurs. When a context has performed a
handover, the console SRCU read lock is released and the pointer to the
console struct might now be invalid. Therefore, after calling
nbcon_legacy_emit_next_record() or console_emit_next_record(), it is
necessary to check if a handover occurred _before_ further @con usage.
Sashiko pointed out that console_flush_one_record() was not doing this.
In console_flush_one_record(), after emitting a record, move the further
usage of @con after the handover check.

How can CyberStrike help with CVE-2026-93134?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-93134 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
