CVE-2025-40091
Description
In the Linux kernel, the following vulnerability has been resolved:
ixgbe: fix too early devlink_free() in ixgbe_remove()
Since ixgbe_adapter is embedded in devlink, calling devlink_free() prematurely in the ixgbe_remove() path can lead to UAF. Move devlink_free() to the end.
KASAN report:
