GHSA-6G9X-RPR5-4QRW

Vulnerability from github – Published: 2025-08-22 18:31 – Updated: 2025-11-26 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: Fix error code in iwl_op_mode_dvm_start()

Preserve the error code if iwl_setup_deferred_work() fails. The current code returns ERR_PTR(0) (which is NULL) on this path. I believe the missing error code potentially leads to a use after free involving debugfs.

Severity ?

7.8 (High)
