CVE-2024-26667: drm/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.22% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 79592a6e7bdc1d05460c95f891f5e5263a107af8, 7f3d03c48b1eb6bc45ab20ca98b8b11be25f9f52, eb4f56f3ff5799ca754ae6d811803a63fe25a4a2.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 79592a6e7bdc1d05460c95f891f5e5263a107af8, 7f3d03c48b1eb6bc45ab20ca98b8b11be25f9f52, eb4f56f3ff5799ca754ae6d811803a63fe25a4a2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup The commit 8b45a26f2ba9 ("drm/msm/dpu: reserve cdm blocks for writeback in case of YUV output") introduced a smatch warning about another conditional block in dpu_encoder_helper_phys_cleanup() which had assumed hw_pp will always be valid which may not necessarily be true. Lets fix the other conditional block by making sure hw_pp is valid before dereferencing it. Patchwork: https://patchwork.freedesktop.org/patch/574878/
