CVE-2026-72146: dmaengine: sh: rz-dmac: Move interrupt request after everything is set up

Noroxi assessment

Priority: Monitor (action score 33/100)

  • 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: 0.18% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 07ae600bd353b22f31a8f1007269744fafc7f123, 0e0c5b3cf374ebf3c589741751e1fbc67f53ec2f, 2a4d9e2234c3f817bb0ddbc8680d09ce9be84f93.

Low priority for now. Upgrade to Linux Linux 07ae600bd353b22f31a8f1007269744fafc7f123, 0e0c5b3cf374ebf3c589741751e1fbc67f53ec2f, 2a4d9e2234c3f817bb0ddbc8680d09ce9be84f93 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: dmaengine: sh: rz-dmac: Move interrupt request after everything is set up Once the interrupt is requested, the interrupt handler may run immediately. Since the IRQ handler can access channel->ch_base, which is initialized only after requesting the IRQ, this may lead to invalid memory access. Likewise, the IRQ thread may access uninitialized data (the ld_free, ld_queue, and ld_active lists), which may also lead to issues. Request the interrupts only after everything is set up. To keep the error path simpler, use dmam_alloc_coherent() instead of dma_alloc_coherent().
