GHSA-MPX6-5VMM-97RR

Vulnerability from github – Published: 2024-03-25 12:30 – Updated: 2024-11-06 18:31

Details

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

iio: adc: ad7124: Fix potential overflow due to non sequential channel numbers

Channel numbering must start at 0 and then not have any holes, or it is possible to overflow the available storage. Note this bug was introduced as part of a fix to ensure we didn't rely on the ordering of child nodes. So we need to support arbitrary ordering but they all need to be there somewhere.

Note I hit this when using qemu to test the rest of this series. Arguably this isn't the best fix, but it is probably the most minimal option for backporting etc.

Alexandru's sign-off is here because he carried this patch in a larger set that Jonathan then applied.

Severity ?

5.5 (Medium)
