CVE-2026-31475
7.8 · HIGHOverview
CVE-2026-31475 is a high-severity vulnerability affecting linux linux_kernel. It was published on April 22, 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:
ASoC: sma1307: fix double free of devm_kzalloc() memory
A previous change added NULL checks and cleanup for allocation
failures in sma1307_setting_loaded().
However, the cleanup for mode_set entries is wrong. Those entries are
allocated with devm_kzalloc(), so they are device-managed resources and
must not be freed with kfree(). Manually freeing them in the error path
can lead to a double free when devres later releases the same memory.
Drop the manual kfree() loop and let devres handle the cleanup.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
