CVE-2024-43877

HighCVSS 7.1/10Last modified Aug 4, 2026

Description

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.
