Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: rtw89: pci: validate sequence number of TX release report

Hardware rarely reports abnormal sequence number in TX release report, which will access out-of-bounds of wd_ring->pages array, causing NULL pointer dereference.
