CVE-2024-53056

Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:
19/11/2024
Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/mediatek: Fix potential NULL dereference in mtk_crtc_destroy()<br /> <br /> In mtk_crtc_create(), if the call to mbox_request_channel() fails then we<br /> set the "mtk_crtc-&gt;cmdq_client.chan" pointer to NULL. In that situation,<br /> we do not call cmdq_pkt_create().<br /> <br /> During the cleanup, we need to check if the "mtk_crtc-&gt;cmdq_client.chan"<br /> is NULL first before calling cmdq_pkt_destroy(). Calling<br /> cmdq_pkt_destroy() is unnecessary if we didn&amp;#39;t call cmdq_pkt_create() and<br /> it will result in a NULL pointer dereference.
