CVE-2026-43142
Description
A flaw was found in the Linux kernel's media: iris: gen1 driver. This vulnerability occurs because the driver fails to destroy internal buffers after the firmware releases them. This oversight leads to stale memory allocations, particularly when display resolutions change and new buffers are required. Over time, this can result in significant memory waste, potentially leading to a Denial of Service (DoS) due to resource exhaustion.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (Other); DoS: Resource Consumption (Memory); DoS: Resource Consumption (CPU)
An attacker that can influence the allocation of resources that are not properly released could deplete the available resource pool and prevent all other processes from accessing the same type of resource. Frequently-affected resources include memory, CPU, disk space, power or battery, etc.
