In the Linux kernel, the following vulnerability has been resolved: drm/bridge: th1520-dw-hdmi: Fix remove() callback This driver stores struct… (CVE-2026-98998)

The Linux kernel's drm/bridge th1520-dw-hdmi driver stored a pointer to struct th1520_hdmi in platform driver data but mistakenly retrieved it as a struct dw_hdmi pointer in the remove() callback. This caused the teardown function dw_hdmi_remove() to operate on an incorrect pointer. The fix involved correctly retrieving the struct th1520_hdmi pointer and passing its dw_hdmi member to dw_hdmi_remove(), ensuring proper resource cleanup.

The improper pointer handling in the remove() callback could lead to incorrect teardown of HDMI bridge resources, potentially causing system instability or resource leaks. No direct exploitation or active attacks are reported.

This vulnerability has been resolved in the Linux kernel. Users should update to a kernel version that includes this fix. No additional mitigation steps are indicated.
