CVE-2023-52678: drm/amdkfd: Confirm list is non-empty before utilizing list_first_entry in kfd_topology.c

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: 0.23% (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 4525525cb7161d08f95d0e47025323dd10214313, 499839eca34ad62d43025ec0b46b80e77065f6d8, 4ac4e023ed7ab1c7c67d2d12b7b6198fcd099e5c.
  • Severity is disputed: the assigning authority (CNA) scores it 7.8, NVD 5.5.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 4525525cb7161d08f95d0e47025323dd10214313, 499839eca34ad62d43025ec0b46b80e77065f6d8, 4ac4e023ed7ab1c7c67d2d12b7b6198fcd099e5c or later.
