CVE-2025-40060: coresight: trbe: Return NULL pointer for allocation failures

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: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 296da78494633e1ab5e2e74173a9c8683b04aa6b, 8a55c161f7f9c1aa1c70611b39830d51c83ef36d, 9768536f82600a05ce901e31ccfabd92c027ff71.

Low priority for now. Upgrade to Linux Linux 296da78494633e1ab5e2e74173a9c8683b04aa6b, 8a55c161f7f9c1aa1c70611b39830d51c83ef36d, 9768536f82600a05ce901e31ccfabd92c027ff71 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: coresight: trbe: Return NULL pointer for allocation failures When the TRBE driver fails to allocate a buffer, it currently returns the error code "-ENOMEM". However, the caller etm_setup_aux() only checks for a NULL pointer, so it misses the error. As a result, the driver continues and eventually causes a kernel panic. Fix this by returning a NULL pointer from arm_trbe_alloc_buffer() on allocation failures. This allows that the callers can properly handle the failure.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
