- Summary
- wifi: iwlwifi: dvm: fix memory leak in iwl_op_mode_dvm_start()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: dvm: fix memory leak in iwl_op_mode_dvm_start()
In iwl_op_mode_dvm_start(), jumping to out_free_eeprom currently bypasses the out_free_eeprom_blob label. Consequently, error paths triggered after successfully parsing the EEPROM free priv->nvm_data but leak priv->eeprom_blob.
Fix this memory leak by reordering the error handling labels so that out_free_eeprom falls through to out_free_eeprom_blob.
The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing v6.13-rc1. The tool is still under development and is not yet publicly available. Manual inspection confirms that the bug is still present in v7.1-rc6.
An x86_64 allyesconfig build showed no new warnings. As we do not have supported Intel DVM wireless hardware and firmware to test with, no runtime testing was able to be performed.
