Overview
CVE-2026-80948 is a known-severity vulnerability. It was published on September 11, 2026.
Technical description
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.

How can CyberStrike help with CVE-2026-80948?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-80948 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
