CVE-2026-23026: dmaengine: qcom: gpi: Fix memory leak in gpi_peripheral_config()

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 01b1d781394fc9b83015e3a3cd46b17bda842bd8, 3f747004bbd641131d9396d87b5d2d3d1e182728, 4532f18e4ab36def1f55cd936d0fc002b2ce34c2.

Low priority for now. Upgrade to Linux Linux 01b1d781394fc9b83015e3a3cd46b17bda842bd8, 3f747004bbd641131d9396d87b5d2d3d1e182728, 4532f18e4ab36def1f55cd936d0fc002b2ce34c2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: dmaengine: qcom: gpi: Fix memory leak in gpi_peripheral_config() Fix a memory leak in gpi_peripheral_config() where the original memory pointed to by gchan->config could be lost if krealloc() fails. The issue occurs when: 1. gchan->config points to previously allocated memory 2. krealloc() fails and returns NULL 3. The function directly assigns NULL to gchan->config, losing the reference to the original memory 4. The original memory becomes unreachable and cannot be freed Fix this by using a temporary variable to hold the krealloc() result and only updating gchan->config when the allocation succeeds. Found via static analysis and code review.
