CVE-2026-98605: drm/bridge: samsung-dsim: fix TE GPIO lifetime for host attach
Noroxi assessment
Priority: Monitor (action score 0/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
- Fixed version: Linux Linux 5759bbef951c39d264ac0f47daa4137d01403aea, 77a43e00c57486a5212ef22d4665cafad62a5d4b, 9b796251c3cca45a33a5c859c6818c58aa982277; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to Linux Linux 5759bbef951c39d264ac0f47daa4137d01403aea, 77a43e00c57486a5212ef22d4665cafad62a5d4b, 9b796251c3cca45a33a5c859c6818c58aa982277; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
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]
