net: mscc: ocelot: Fix crash when adding interface under a lag
Noroxi assessment
Priority: Monitor (action score 22/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.13% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 03fb1708b7d1e76aecebf767ad059c319845039f, 2985712dc76dfa670eb7fd607c09d4d48e5f5c6e, 34f3ff52cb9fa7dbf04f5c734fcc4cb6ed5d1a95; cbl2 kernel 5.15.186.1-1 on CBL Mariner 2.0 5.15.200.1-1.
Low priority for now. Upgrade to Linux Linux 03fb1708b7d1e76aecebf767ad059c319845039f, 2985712dc76dfa670eb7fd607c09d4d48e5f5c6e, 34f3ff52cb9fa7dbf04f5c734fcc4cb6ed5d1a95; cbl2 kernel 5.15.186.1-1 on CBL Mariner 2.0 5.15.200.1-1 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
In the Linux kernel, the following vulnerability has been resolved: net: mscc: ocelot: Fix crash when adding interface under a lag Commit 15faa1f67ab4 ("lan966x: Fix crash when adding interface under a lag") fixed a similar issue in the lan966x driver caused by a NULL pointer dereference. The ocelot_set_aggr_pgids() function in the ocelot driver has similar logic and is susceptible to the same crash. This issue specifically affects the ocelot_vsc7514.c frontend, which leaves unused ports as NULL pointers. The felix_vsc9959.c frontend is unaffected as it uses the DSA framework which registers all ports. Fix this by checking if the port pointer is valid before accessing it.
