CVE-2021-47562

Summary (CVE-2021-47562) : In Linux kernel ice driver, a mismatch in XDP/Rx/Tx queue sizing caused by vsi->txq_map being sized to the doubled vsi->alloc_txq could trigger a kernel NULL pointer dereference when ethtool -L configures XDP rings and Rx/Tx counts differ. The root cause is the tx...
