Overview

CVE-2026-64145 is a high-severity vulnerability. It was published on July 19, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

wifi: wilc1000: fix dma_buffer leak on bus acquire failure

wilc_wlan_firmware_download() allocates dma_buffer with kmalloc() at

the top of the function and uses a 'fail:' label to free it via

kfree(dma_buffer) on error.

All later error paths correctly use 'goto fail' to route through this

cleanup. However, the early failure path after the first acquire_bus()

call uses a bare 'return ret;', which leaks dma_buffer whenever the bus

acquire fails.

Replace the early return with goto fail so the existing cleanup path

runs.

Found via a custom Coccinelle semantic patch hunting for kmalloc'd

locals leaked on early-return error paths in driver firmware-download

code.

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.
