Technical details
A double-free vulnerability exists in the Samsung Exynos DPU driver due to improper pointer management during DMA buffer reallocation. The vulnerability allows an attacker to free the same memory location twice, leading to kernel heap corruption and potential use-after-free conditions. Attack preconditions and vector details are not fully specified in available documentation, but exploitation could result in denial of service or privilege escalation depending on memory layout and kernel protections. Affected Exynos processors include models 1280, 2200, 1380, 1480, 2400, 1580, 2500, 1680, and 2600. Patch status and mitigation availability require verification with Samsung security updates.
