CVE-2026-90368: Linux kernel Wi‑Fi driver may leak resources on failure
CVE-2026-90368 · published 1 month ago
Summary
The Wi‑Fi driver used in Debian and Ubuntu Linux systems can leave internal data behind if it fails to add a network interface. This leftover data could cause the system to run out of resources or behave unpredictably over time. Updating the kernel to the latest version resolves the issue.
What to do
- Update debian linux to version 7.2.6-1.
- Update linux kernel to version 7.2.6.
- Update bellsoft linux-lts to version 6.18.53-r0.
- Update debian linux to version 6.12.111-1.
- Update bellsoft linux-lts to version 6.12.111-r0.
- Update debian linux-6.12 to version 6.12.111-1~deb12u1.
- Update canonical linux-hwe-7.0 to version 7.0.0-42.42~24.04.1.
- Update canonical linux-riscv-7.0 to version 7.0.0-42.42.1~24.04.1.
- Update canonical linux to version 7.0.0-42.42.
- Update canonical linux-aws to version 7.0.0-1016.17.
- Update canonical linux-gcp to version 7.0.0-1016.18.
- Update canonical linux-ibm to version 7.0.0-1017.17.
- Update canonical linux-oem-7.0 to version 7.0.0-1017.17.
- Update canonical linux-oracle to version 7.0.0-1015.16.
- Update canonical linux-riscv to version 7.0.0-42.42.1.
- Update bellsoft linux-lts to version 6.1.191-r0.
- Update linux linux to version 09f3dced52c22d9b20f356b01986c5ea0f446cea or later.

Original advisory text
BELL-CVE-2026-90368
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: unwind state on add_interface failure When mt76_wcid_alloc() fails, mt7915_add_interface() returned without clearing the vif_mask/omac_mask bits it had already set, without removing the firmware dev info added earlier, and without clearing a monitor_vif pointer to the vif mac80211 is about to free. mac80211 does not call remove_interface() for a failed add, so the indices and firmware dev entry leaked permanently and testmode could dereference the stale monitor_vif. Add a proper error unwind.
