CVE-2026-80743

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

ASoC: xilinx: formatter_pcm: pass aud_drv_data to irq handlers

The irq handlers take a struct device pointer and call

dev_get_drvdata() to obtain the driver data. However, the driver

data is only set at the end of probe, after devm_request_irq(),

so an interrupt taken in between causes the handlers to pass a

NULL pointer to readl() and crash.

Pass the private data directly as the devm_request_irq() argument

instead of the device pointer, matching what the handlers expect.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
