CVE-2024-47667

Summary

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

PCI: keystone: Add workaround for Errata #i2037 (AM65x SR 1.0)

Errata #i2037 in AM65x/DRA80xM Processors Silicon Revision 1.0 (SPRZ452D_July 2018_Revised December 2019 [1]) mentions when an inbound PCIe TLP spans more than two internal AXI 128-byte bursts, the bus may corrupt the packet payload and the corrupt data may cause associated applications or the processor to hang.

The workaround for Errata #i2037 is to limit the maximum read request size and maximum payload size to 128 bytes. Add workaround for Errata #i2037 here.

The errata and workaround is applicable only to AM65x SR 1.0 and later versions of the silicon will have this fixed.
