HIGH 7.8

DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

spi: ti-qspi: fix use-after-free after DMA setup failure

The driver falls back to PIO mode if DMA setup fails during probe.

Make sure to clear the DMA channel pointer also if buffer allocation fails to avoid passing a pointer to the released channel to the DMA engine (or trying to free the channel a second time on late probe errors or driver unbind).

This issue was flagged by Sashiko when reviewing a devres allocation conversion patch.

AnalysisAI

Local privilege escalation in the Linux kernel's ti-qspi SPI driver results from a use-after-free when DMA setup fails, allowing a local attacker to potentially execute arbitrary code or crash the system. The vulnerability affects Linux kernels from version 4.12 up to the patched stable releases 5.10.258, 5.15.209, 6.1.175, 6.6.142, 6.12.92, 6.18.34, 7.0.11, and 7.1. No active exploitation has been confirmed (CISA KEV not listed), and the EPSS probability is low (0.18%), indicating limited real-world likelihood.
