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...

CVE-2021-47562 ice: fix vsi->txq_map sizing

In the Linux kernel, the following vulnerability has been resolved: ice: fix vsi-txqmap sizing The approach of having XDP queue per CPU regardless of user's setting exposed a hidden bug that could occur in case when Rx queue count differ from Tx queue count. Currently vsi-txqmap's size is equal t...
