Answer in brief
CVE-2022-48779 records a High severity (CVSS 7.8) vulnerability in net: mscc: ocelot: fix use-after-free in ocelot_vlan_del(). The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: net: mscc: ocelot: fix use-after-free in ocelot_vlan_del() ocelot_vlan_member_del() will free the struct ocelot_bridge_vlan, so if this is the same as the port's pvid_vlan which we access afterwards, what we're accessing is freed memory. Fix the bug by determining whether to clear ocelot_port->pvid_vlan prior to calling ocelot_vlan_member_del().
