CVE-2026-72485: coresight: platform: defer connection counter increment until alloc succeeds

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.16% (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 09c44549820df67048be3ba19c723bac72ebb98e, 1563ae33dc4f5ebac96b93af2ef72e72aaaa31ae, 8ca9adc805884d3bb5038082462577f86c2c4a10.

Low priority for now. Upgrade to Linux Linux 09c44549820df67048be3ba19c723bac72ebb98e, 1563ae33dc4f5ebac96b93af2ef72e72aaaa31ae, 8ca9adc805884d3bb5038082462577f86c2c4a10 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: coresight: platform: defer connection counter increment until alloc succeeds coresight_add_out_conn() increments nr_outconns before calling devm_krealloc_array() and again before devm_kmalloc(). If either allocation fails, the counter is already bumped while the corresponding array entry is NULL or uninitialized garbage. coresight_add_in_conn() has the same problem with nr_inconns and devm_krealloc_array(). In both cases the probe returns -ENOMEM, which causes coresight_get_platform_data() to call coresight_release_platform_data() for cleanup. That function iterates up to nr_outconns (or nr_inconns) entries and dereferences each pointer unconditionally, hitting the NULL or garbage entry and panicking instead of failing gracefully. Fix by moving the counter increments to after all allocations succeed, so the struct is always consistent on any error path.
