  3. CVE-2025-21894
In the Linux kernel, the following vulnerability has been resolved: net: enetc: VFs do not support HWTSTAMP_TX_ONESTEP_SYNC Actually ENETC VFs do not support HWTSTAMP_TX_ONESTEP_SYNC because only ENETC PF can access PMa_SINGLE_STEP registers. And there will be a crash if VFs are used to test one-step timestamp, the crash log as follows. [ 129.110909] Unable to handle kernel paging request at virtual address 00000000000080c0 [ 129.287769] Call trace: [ 129.290219] enetc_port_mac_wr+0x30/0xec (P) [ 129.294504] enetc_start_xmit+0xda4/0xe74 [ 129.298525] enetc_xmit+0x70/0xec [ 129.301848] dev_hard_start_xmit+0x98/0x118

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: enetc: Las funciones virtuales no admiten HWTSTAMP_TX_ONESTEP_SYNC. En realidad, las funciones virtuales de ENETC no admiten HWTSTAMP_TX_ONESTEP_SYNC porque solo la función de protección de ENETC puede acceder a los registros PMa_SINGLE_STEP. Se producirá un fallo si se utilizan funciones virtuales para probar la marca de tiempo de un paso. El registro de fallos es el siguiente. [ 129.110909] No se puede gestionar la solicitud de paginación del kernel en la dirección virtual 00000000000080c0 [ 129.287769] Rastreo de llamadas: [ 129.290219] enetc_port_mac_wr+0x30/0xec (P) [ 129.294504] enetc_start_xmit+0xda4/0xe74 [ 129.298525] enetc_xmit+0x70/0xec [ 129.301848] dev_hard_start_xmit+0x98/0x118
