CVE-2026-89444: platform/x86: dell-wmi-sysman: Don't hex dump attribute security buffer

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: 0.21% (FIRST EPSS).
  • Fixed version: Linux Linux 22222f92b0a5116eb4aac4be81e7b770adfa32ee, 23ba9a18896e198f837ae54be99c8852c41890f7, 26f554f9f0fb603f76291c10b1cf979241bd2273.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 22222f92b0a5116eb4aac4be81e7b770adfa32ee, 23ba9a18896e198f837ae54be99c8852c41890f7, 26f554f9f0fb603f76291c10b1cf979241bd2273 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: platform/x86: dell-wmi-sysman: Don't hex dump attribute security buffer set_attribute() populates the security area of the BIOS attribute request buffer with the current admin password via populate_security_buffer(), then dumps the whole request buffer with print_hex_dump_bytes(). This can expose the plaintext admin password in the kernel log. The same issue was fixed for the password attribute path by commit d1a196e0a6dc ("platform/x86: dell-wmi-sysman: Don't hex dump plaintext password data"). Remove the remaining dump from the BIOS attribute path.
