Detailed vulnerability description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a race condition leading to a NULL pointer dereference in the ice TX timestamp ring handling when processing transmit operations concurrently with TX timestamp ring cleanup. A local user can trigger concurrent ring cleanup and transmit mapping operations to cause a denial of service.
The issue occurs because one CPU can observe the TXTIME flag as set after the timestamp ring pointer has already been cleared on another CPU.
