NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-modules-partner package and not the kernel-debug-modules-partner package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

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

atl1c: Work around the DMA RX overflow issue

This is based on alx driver commit 881d0327db37 ("net: alx: Work around the DMA RX overflow issue").

The alx and atl1c drivers had RX overflow error which was why a custom allocator was created to avoid certain addresses. The simpler workaround then created for alx driver, but not for atl1c due to lack of tester.

Instead of using a custom allocator, check the allocated skb address and use skb_reserve() to move away from problematic 0x...fc0 address.

Tested on AR8131 on Acer 4540.
