CVE-2026-46129

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A double free issue exists in the btrfs module within the create space info() function error path. When kobject init and add() fails, the system executes a call chain that leads to space info release() and subsequently kfree(space info). Control then returns to create space info(), which triggers another kfree(space info) call via the out free label, resulting in the memory being freed twice.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
