  3. CVE-2026-23117
In the Linux kernel, the following vulnerability has been resolved: ice: add missing ice_deinit_hw() in devlink reinit path devlink-reload results in ice_init_hw failed error, and then removing the ice driver causes a NULL pointer dereference. [ +0.102213] ice 0000:ca:00.0: ice_init_hw failed: -16 ... [ +0.000001] Call Trace: [ +0.000003] <TASK> [ +0.000006] ice_unload+0x8f/0x100 [ice] [ +0.000081] ice_remove+0xba/0x300 [ice] Commit 1390b8b3d2be ("ice: remove duplicate call to ice_deinit_hw() on error paths") removed ice_deinit_hw() from ice_deinit_dev(). As a result ice_devlink_reinit_down() no longer calls ice_deinit_hw(), but ice_devlink_reinit_up() still calls ice_init_hw(). Since the control queues are not uninitialized, ice_init_hw() fails with -EBUSY. Add ice_deinit_hw() to ice_devlink_reinit_down() to correspond with ice_init_hw() in ice_devlink_reinit_up().

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: ice: añadir la llamada faltante a ice_deinit_hw() en la ruta de reinicio de devlink devlink-reload resulta en un error de fallo de ice_init_hw, y luego la eliminación del controlador ice causa una desreferencia de puntero NULL. [ +0.102213] ice 0000:ca:00.0: ice_init_hw falló: -16 ... [ +0.000001] Traza de Llamadas: [ +0.000003] [ +0.000006] ice_unload+0x8f/0x100 [ice] [ +0.000081] ice_remove+0xba/0x300 [ice] El commit 1390b8b3d2be ('ice: eliminar llamada duplicada a ice_deinit_hw() en rutas de error') eliminó ice_deinit_hw() de ice_deinit_dev(). Como resultado, ice_devlink_reinit_down() ya no llama a ice_deinit_hw(), pero ice_devlink_reinit_up() todavía llama a ice_init_hw(). Dado que las colas de control no están desinicializadas, ice_init_hw() falla con -EBUSY. Añadir ice_deinit_hw() a ice_devlink_reinit_down() para corresponder con ice_init_hw() en ice_devlink_reinit_up().
