Description

This security bulletin contains information about 1 vulnerability.


1) Improper Initialization (CVE-ID: CVE-2026-64500)

CWE-ID: CWE-665 - Improper Initialization

CVSSv4: 5.7 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper initialization in lpc32xx_adc_probe() and the lpc32xx ADC interrupt handling path when handling a spurious interrupt during device probe before completion initialization. A local user can trigger a device state that causes an interrupt to arrive before init_completion() to cause a denial of service.

The issue can lead to a kernel panic through a NULL pointer dereference and resulting wild memory access in the interrupt wake-up path.
