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