Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
net: atlantic: Fix DMA mapping for PTP hwts ring
Function aq_ring_hwts_rx_alloc() maps extra AQ_CFG_RXDS_DEF bytes for PTP HWTS ring but then generic aq_ring_free() does not take this into account. Create and use a specific function to free HWTS ring to fix this issue.
