| Subject: CVE-2024-47667: PCI: keystone: Add workaround for Errata #i2037 (AM65x SR 1.0) |
| |
| Description |
| =========== |
| |
| 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. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
