CVE-2026-98605
In the Linux kernel, the following vulnerability has been resolved: drm/bridge: samsung-dsim: fix TE GPIO lifetime for host attach When the Exynos DSI driver was generalized into samsung-dsim, the TE GPIO acquisition was switched from gpiod_get_optional() to devm_gpiod_get_optional() while keeping the matching gpiod_put() calls. That combination is wrong for a managed descriptor. However, dropping the puts and keeping the managed get is also wrong: samsung_dsim_register_te_irq() runs from the DSI host attach callback, and host detach/reattach can happen without destroying the device that owns the managed action. A second attach would then request the GPIO again without having released it. Switch back to a non-managed gpiod_get_optional() and keep the explicit gpiod_put() on the request_irq() error path and in samsung_dsim_unregister_te_irq(). [Luca: remove unnecessary comment]
