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.

  BUG: kernel NULL pointer dereference, address: 0000000000000000
  #PF: supervisor read access in kernel mode
  #PF: error_code(0x0000) - not-present page
  PGD 0 P4D 0
  Oops: 0000 [#1] PREEMPT SMP NOPTI
  CPU: 1 PID: 1085 Comm: irq/129-rtw89_p Tainted: G S   U
