CVE-2026-92476: crypto: keembay - Initialize completion before requesting IRQ

• Severity: unknown
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-09-17 · updated 2026-10-19

Description

In the Linux kernel, the following vulnerability has been resolved: crypto: keembay - Initialize completion before requesting IRQ kmb_ocs_aes_probe() requests the device IRQ before initializing irq_completion. Once the handler is registered it can run immediately, and ocs_aes_irq_handler() unconditionally calls complete(). An interrupt in this window would therefore use an uninitialized completion. Initialize the completion before requesting the IRQ, as the sibling OCS HCU and ECC drivers already do.

Affected products

• Linux kernel: 5.11 — fixed in 7.3

How to fix

Upgrade to a fixed version: Linux kernel 7.3. Check the vendor advisory for mitigations.
