Description

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.

Affected configurations

• linux linux kernel (>= 5.10.1 < 5.15.198) • linux linux kernel (>= 5.16 < 6.1.161) • linux linux kernel (>= 6.2 < 6.6.121) • linux linux kernel (>= 6.7 < 6.12.66) • linux linux kernel (>= 6.13 < 6.18.6) • linux linux kernel 5.10 • linux linux kernel 6.19
