No severity ratings or metrics are available. When they are, we'll update the corresponding info on the page.
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.12.34-gbe78e49cb433
Description The Linux kernel contains a flaw within the USB qmi wwan component related to the initialization of the MAC header offset in the qmimux rx fixup function. Raw IP packets lack a MAC header, potentially leaving skb->mac header uninitialized. This can lead to kernel panics on ARM64 systems when subsystems like xfrm access this offset due to strict alignment checks. Specifically, kernel panics may occur on ARM when running IPsec over the qmimux0 interface. The xfrm input function is implicated in the crash trace.
Recommendations Update to Linux kernel version 6.12.34-gbe78e49cb433 or later.
