CVE-2026-64602

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

Description An issue exists in the spear adc probe() function within drivers/iio/adc/spear adc.c where the interrupt handler is registered using devm request irq() before the st->completion variable is initialized via init completion(). If an interrupt occurs after the handler registration but before initialization, the spear adc isr() function calls complete() on the uninitialized st->completion variable. This leads to the acquisition of an uninitialized wait.lock and the traversal of a zeroed task list in swake up locked(), resulting in a NULL list entry dereference and a kernel panic (KASAN wild-memory-access).

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