Fix Version: 10.24.33.8
Severity: Standard
Applicable for: Wind River Linux LTS 24
Component/s: Kernel
In the Linux kernel, the following vulnerability has been resolved:
sched: address a potential NULL pointer dereference in the GRED scheduler.
If kzalloc in gred_init returns a NULL pointer, the code follows the
error handling path, invoking gred_destroy. This, in turn, calls
gred_offload, where memset could receive a NULL pointer as input,
potentially leading to a kernel crash.
When table->opt is NULL in gred_init(), gred_change_table_def()
is not called yet, so it is not necessary to call ->ndo_setup_tc()
in gred_offload().
