In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: xgmac: fix handling of DPP safety error for DMA channels
Commit 56e58d6c8a56 (“net: stmmac: Implement Safety Features in
XGMAC core”) checks and reports safety errors, but leaves the
Data Path Parity Errors for each channel in DMA unhandled at all, lead to
a storm of interrupt.
Fix it by checking and clearing the DMA_DPP_Interrupt_Status register.
