Vulnerability from github – Published: 2025-09-15 15:31 – Updated: 2025-12-03 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

power: supply: fix null pointer dereferencing in power_supply_get_battery_info

when kmalloc() fail to allocate memory in kasprintf(), propname will be NULL, strcmp() called by of_get_property() will cause null pointer dereference.

So return ENOMEM if kasprintf() return NULL pointer.

Severity

5.5 (Medium)
