CVE-2025-71147: KEYS: trusted: Fix a memory leak in tpm2_load_cmd

MediumCVSS 5.5 · v3.1—No exploit Fix available

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: 0.14% (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 19166de9737218b77122c41a5730ac87025e089f, 3fd7df4636d8fd5e3592371967a5941204368936, 62cd5d480b9762ce70d720a81fa5b373052ae05f; cbl2 kernel 5.15.186.1-1 on CBL Mariner 2.0 5.15.200.1-1.

Low priority for now. Upgrade to Linux Linux 19166de9737218b77122c41a5730ac87025e089f, 3fd7df4636d8fd5e3592371967a5941204368936, 62cd5d480b9762ce70d720a81fa5b373052ae05f; cbl2 kernel 5.15.186.1-1 on CBL Mariner 2.0 5.15.200.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: KEYS: trusted: Fix a memory leak in tpm2_load_cmd 'tpm2_load_cmd' allocates a tempoary blob indirectly via 'tpm2_key_decode' but it is not freed in the failure paths. Address this by wrapping the blob into with a cleanup helper.
