CVE-2024-43877 Open this link in a new tabHow to fix?
There is no fixed version for RHEL:7 kernel-rt.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt package and not the kernel-rt package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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.
