CVE-2023-52691: drm/amd/pm: fix a double-free in si_dpm_init

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.24% (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 06d95c99d5a4f5accdb79464076efe62e668c706, 2bf47c89bbaca2bae16581ef1b28aaec0ade0334, ac16667237a82e2597e329eb9bc520d1cf9dff30.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 06d95c99d5a4f5accdb79464076efe62e668c706, 2bf47c89bbaca2bae16581ef1b28aaec0ade0334, ac16667237a82e2597e329eb9bc520d1cf9dff30 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: fix a double-free in si_dpm_init When the allocation of adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, amdgpu_free_extended_power_table is called to free some fields of adev. However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. Thus a double-free is triggered.
