Subject: [DPDK/core Bug 2111] eal: rte_dev_probe() rollback can call local_dev_remove(NULL)
Date: Thu, 12 Nov 2026 17:38:17 +0000 [thread overview]
Message-ID: <bug-2111-3@https.bugs.dpdk.org/> (raw)
https://bugs.dpdk.org/show_bug.cgi?id=2111
Bug ID: 2111
Summary: eal: rte_dev_probe() rollback can call
local_dev_remove(NULL)
Product: DPDK
Version: 26.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: minor
Priority: Normal
Component: core
Assignee: dev@dpdk.org
Reporter: stephen@networkplumber.org
Target Milestone: ---
local_dev_probe() sets *new_dev = NULL (lib/eal/common/eal_common_dev.c:186)
and can return at :252 without setting it. rte_dev_probe() continues on -EEXIST
(:321); if the secondary sync then fails it reaches rollback: and calls
local_dev_remove(dev) (:369) with dev == NULL, which dereferences it (:405).
Narrow path.
