In the Linux kernel, the following vulnerability has been resolved:
net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()
The function ice_bridge_setlink() may encounter a NULL pointer dereference if nlmsg_find_attr() returns NULL and br_spec is dereferenced subsequently in nla_for_each_nested(). To address this issue, add a check to ensure that br_spec is not NULL before proceeding with the nested attribute iteration.
AnalysisAI
In the Linux kernel, the following vulnerability has been resolved: net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink() The function ice_bridge_setlink() may encounter a NULL. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
Technical ContextAI
This vulnerability is classified as NULL Pointer Dereference (CWE-476), which allows attackers to crash the application by dereferencing a null pointer. In the Linux kernel, the following vulnerability has been resolved: net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink() The function ice_bridge_setlink() may encounter a NULL pointer dereference if nlmsg_find_attr() returns NULL and br_spec is dereferenced subsequently in nla_for_each_nested(). To address this issue, add a check to ensure that br_spec is not NULL before proceeding with the nested attribute iteration. Affected products include: Linux Linux Kernel, Debian Debian Linux.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Check pointers before dereferencing. Use static analysis tools to detect null pointer paths.
