Linux hwe edge: In the Linux kernel, the following vulnerability has been resolved: iio: light: gp2ap002: fix runtime PM leak on read error gp2ap002_read_raw()… (CVE-2026-64494)
A vulnerability in the Linux kernel's gp2ap002 light sensor driver caused a runtime power management (PM) reference leak on read errors. The issue occurred because the function gp2ap002_read_raw() called pm_runtime_get_sync() but returned directly on error without calling pm_runtime_put_autosuspend(), preventing the device from autosuspending. This flaw has been fixed by ensuring the reference is properly dropped on error paths. The vulnerability affects multiple versions of the linux-hwe-edge kernel prior to 7.0.0-31.31 and related versions. A patch is available and included in updated kernel packages.
AI Analysis
Technical Summary
The Linux kernel's gp2ap002 light sensor driver had a bug where the runtime PM reference was leaked if gp2ap002_get_lux() failed during gp2ap002_read_raw(). The function called pm_runtime_get_sync() before reading the lux value but returned immediately on error, skipping the pm_runtime_put_autosuspend() call that would release the PM reference. This caused a permanent leak of the runtime PM reference, preventing the device from autosuspending properly. The fix replaces the direct return with a 'goto out' to ensure proper cleanup. This vulnerability is resolved in linux-hwe-edge kernel versions 7.0.0-31.31 and later.
Potential Impact
The vulnerability causes a runtime power management reference leak on error conditions in the gp2ap002 light sensor driver, which prevents the device from autosuspending. This may lead to increased power consumption and reduced battery life on affected systems. There is no indication of privilege escalation or remote code execution from this issue. No known exploits are reported in the wild.
Mitigation Recommendations
A patch is available and should be applied by updating to the fixed kernel versions as provided by the vendor. After updating, a system reboot is required to apply the changes. Users should upgrade linux-hwe-edge kernel packages to versions 7.0.0-31.31 or later to remediate this issue. No additional mitigation steps are necessary.
