CVE-2026-89474

A flaw was found in the Linux kernel's power supply subsystem, specifically within the bq256xx driver. This vulnerability occurs when a USB work item attempts to access a charger object after it has been freed. This timing issue can lead to a use-after-free condition, potentially causing system...

CVE-2026-89474

CVE-2026-89474 is a use-after-free in the Linux kernel's bq256xx power supply driver. On driver removal, the USB-PHY notifier queues a work item (usb_work) whose handler calls power_supply_changed(bq->charger). Because the reset devm action was registered before the power supplies, the devm un...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: power: supply: bq256xx: Fixed a use-after-free in powersupplychanged. Using the devm variant for requesting IRQs before using the devm variant for allocating/registering the powersupply handle means that the powersupply handle wi...

CVE-2026-45902

A flaw was found in the Linux kernel's bq256xx power supply driver. A race condition during device removal or probing can lead to a use-after-free vulnerability. This occurs when an interrupt handler attempts to access a power supply handle that has already been freed or is uninitialized. A local...
