CVE-2026-64023

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the gpio aggregator. The problem occurs when aggr->lookups->dev id is freed during an error sequence before the corresponding entry is removed from the lookup table. A concurrent thread executing gpiod find() may iterate over the list and trigger gpiod match lookup table(), which dereferences the dev id variable when calling strcmp(), leading to a potential crash or memory corruption.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
