CVE-2023-52834 is a DMA receive-overflow flaw in the Linux kernel atl1c Ethernet driver. The issue affects receive-buffer allocation for hardware using the atl1c driver: DMA operations can encounter an overflow condition when an allocated socket-buffer address has a problematic alignment or address offset. The upstream workaround examines the allocated socket-buffer address and reserves additional buffer space to move the DMA target away from the problematic address range.
