GHSA-C6J3-5H93-CJ2J

Vulnerability from github – Published: 2024-08-21 03:31 – Updated: 2025-11-04 00:31

Details

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

media: pci: ivtv: Add check for DMA map result

In case DMA fails, 'dma->SG_length' is 0. This value is later used to access 'dma->SGarray[dma->SG_length - 1]', which will cause out of bounds access.

Add check to return early on invalid value. Adjust warnings accordingly.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Severity ?

7.1 (High)
