CVE-2026-98785: drm/amd/display: check dc_state_create_copy() for NULL in dm_suspend

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: 0.18% (FIRST EPSS).
  • Fixed version: Linux Linux 015e72cde567d2450e282c2790773463156b2d0a, 0b24f9d4e6e8ab64da8f2ae85bd1790d0f6a596f, 197946faa1b7968046ba475ae2f266847c6f51ed; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.159.1-1.

Low priority for now. Upgrade to Linux Linux 015e72cde567d2450e282c2790773463156b2d0a, 0b24f9d4e6e8ab64da8f2ae85bd1790d0f6a596f, 197946faa1b7968046ba475ae2f266847c6f51ed; 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/amd/display: check dc_state_create_copy() for NULL in dm_suspend dc_state_create_copy() can return NULL on allocation failure. dm_suspend() only conditionally skips dm_gpureset_toggle_interrupts() and continues execution, returning success. dm_resume() then dereferences the NULL cached_dc_state in link_enc_cfg_copy() and the following dc_state->stream_count loop, crashing during GPU reset recovery. Return -ENOMEM immediately if the copy fails, so the caller aborts suspend instead of leaving a NULL cached state for resume. (cherry picked from commit 84b6d7932fdd2857795a257f9f258562a3cddcab)
