DEBIAN-CVE-2026-23164 PUBLISHED CVSS 5.5 MEDIUM

In the Linux kernel, the following vulnerability has been resolved: rocker: fix memory leak in rocker_world_port_post_fini() In rocker_world_port_pre_init(), rocker_port->wpriv is allocated with kzalloc(wops->port_priv_size, GFP_KERNEL). However, in rocker_world_port_post_fini(), the memory is only freed when wops->port_post_fini callback is set: if (!wops->port_post_fini) return; wops->port_post_fini(rocker_port); kfree(rocker_port->wpriv); Since rocker_ofdpa_ops does not implement port_post_fini callback (it is NULL), the wpriv memory allocated for each port is never freed when ports are removed. This leads to a memory leak of sizeof(struct ofdpa_port) bytes per port on every device removal. Fix this by always calling kfree(rocker_port->wpriv) regardless of whether the port_post_fini callback exists.
