CVE-2026-23117
N/A
Summary
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().
