Summary
The Samsung GPU driver on Samsung Semiconductor Exynos 1580, Exynos 2500, Exynos 2600 and Exynos 1680 is affected before October 2026. Improper reference count handling during command submission causes a use-after-free (CWE-416), which can lead to memory corruption. The sources do not describe the attacker or required access, and the flaw is not listed in CISA KEV and has no exploit link.
