CVE intelligence and bounded remediation
CVE-2026-23117 — Linux Linux Kernel security vulnerability
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().

Matched remediation archetype
Buffer bounds, memory safety, and memory corruption
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
- Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
- Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.
Remediate safely
- Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
- Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
- Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
