CVE-2026-97978

eth: ice: don't dereference pointers from TP_printk()

State: Published
Severity: Not scored
Published: Sep 25, 2026
Updated: Oct 21, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

eth: ice: don't dereference pointers from TP_printk()

After forwarding net-next during the v7.3 merge window we started seeing:

TRACE EVENT ERROR: Event ice_tx_dim_work has double dereference in TP_printk: REC->q_vector->tx.tx_ring->q_index WARNING: kernel/trace/trace_events.c:420 at test_double_dereference.cold+0x39/0x4b

this is due to extra checks added in tracing subsystem in commit b5cc230af5e5 ("tracing: Warn when an event dereferences a pointer in TP_printk()").

Printing happens long after the event was recorded, by which point the pointers may be invalid (the ring or the dim instance). Copy the eight scalars into the event instead.
