CVE-2026-23019

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: marvell: prestera: fix NULL dereference on devlink_alloc() failure<br /> <br /> devlink_alloc() may return NULL on allocation failure, but<br /> prestera_devlink_alloc() unconditionally calls devlink_priv() on<br /> the returned pointer.<br /> <br /> This leads to a NULL pointer dereference if devlink allocation fails.<br /> Add a check for a NULL devlink pointer and return NULL early to avoid<br /> the crash.
