CVE-2025-71185: dmaengine: ti: dma-crossbar: fix device leak on am335x route allocation

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: 0.21% (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 1befa553f1ecc045dc9ff56107ff50162f63f3c0, 30352277d8e09c972436f883a5efd1f1b763ac14, 43725bd47d984937c429919ae291896d982d1f17.

Low priority for now. Upgrade to Linux Linux 1befa553f1ecc045dc9ff56107ff50162f63f3c0, 30352277d8e09c972436f883a5efd1f1b763ac14, 43725bd47d984937c429919ae291896d982d1f17 or later.
