Overview
CVE-2026-64498 is a known-severity vulnerability. It was published on July 25, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
iio: buffer: hw-consumer: free scan_mask on buffer release
The scan_mask lifetime changed in commit 9a2e1233d38c ("iio: buffer:
hw-consumer: remove redundant scan_mask flexible array").
Before that change, the scan mask storage was embedded in struct
hw_consumer_buffer, so iio_hw_buf_release() could free the whole
allocation with a single kfree(hw_buf).
That commit moved the scan mask to a separate bitmap_zalloc() allocation
stored in buffer.scan_mask, but left iio_hw_buf_release() unchanged.
Free the scan mask in iio_hw_buf_release() before freeing the buffer
wrapper.

How can CyberStrike help with CVE-2026-64498?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-64498 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.
