CVE-2026-68410
Detail
Received This CVE record has recently been published to the CVE List and has been included within the NVD dataset.
Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: libertas: fix memory leak in helper_firmware_cb()
helper_firmware_cb() neglects to free the single-stage firmware image
after a successful async load, leading to a memory leak in the USB
firmware-download path.
Fix this memory leak by calling release_firmware() immediately after
lbs_fw_loaded() returns.
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
the current wireless tree.
An x86_64 allyesconfig build showed no new warnings. As we do not have
compatible Libertas USB hardware for exercising this firmware-download
path, no runtime testing was able to be performed.
