Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.2.9
Description
The issue is related to a race condition and resultant use-after-free in the drivers/power/supply/da9150-charger.c driver of the Linux kernel. This occurs when a physically proximate attacker unplugs a device, potentially leading to a denial of service. The vulnerability is associated with the
da9150 charger remove() function and the use of shared resources.Recommendations
For Linux kernel versions prior to 6.2.9, update to version 6.2.9 or later to resolve the issue.
As a temporary workaround, consider restricting access to the
da9150-charger.c driver to minimize the risk of exploitation.Fix
