## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> Linux kernel versions with the bq24257 power supply driver are affected by a use-after-free on device removal, where a delayed work item could run against memory already freed. The source does not state the attacker's access requirements or the full consequences. The fix is to upgrade to a fixed Linux kernel build for your branch, such as 5.10.273 or later in the 5.10 series, or the corresponding stable release for your version.
