CVE-2026-72148: dmaengine: dw-edma: Add spinlock to protect DONE_INT_MASK and ABORT_INT_MASK

Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 0.32% (FIRST EPSS).
  • Someone on the same network segment 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 1553ca96e9df158d8f37137cf4bf5fb0dc981d94, 21a9834f56d6249aaa6ca7c2d8c182d66c48c3e1, 2247cc25a91fb1b5b86586ed55fdd5b725a7477c.

Low priority for now. Upgrade to Linux Linux 1553ca96e9df158d8f37137cf4bf5fb0dc981d94, 21a9834f56d6249aaa6ca7c2d8c182d66c48c3e1, 2247cc25a91fb1b5b86586ed55fdd5b725a7477c or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: Add spinlock to protect DONE_INT_MASK and ABORT_INT_MASK The DONE_INT_MASK and ABORT_INT_MASK registers are shared by all DMA channels, and modifying them requires a read-modify-write sequence. Because this operation is not atomic, concurrent calls to dw_edma_v0_core_start() can introduce race conditions if two channels update these registers simultaneously. Add a spinlock to serialize access to these registers and prevent race conditions. [den: update dw_edma.lock comment]
