A flaw was found in the Linux kernel. This memory leak vulnerability exists in the driver core location component, where the `acpi_pld_info` structure is not properly freed upon allocation failure. A local attacker could exploit this flaw to cause a denial of service (DoS) due to resource exhaustion.

Description OSIDB Bzimport 2025-09-15 15:12:57 UTC 
In the Linux kernel, the following vulnerability has been resolved:

driver core: location: Free struct acpi_pld_info *pld before return false

struct acpi_pld_info *pld should be freed before the return of allocation
failure, to prevent memory leak, add the ACPI_FREE() to fix it.
