Description
In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: rpmpd: Check for null return of devm_kcalloc
Because of the possible failure of the allocation, data->domains might
be NULL pointer and will cause the dereference of the NULL pointer
later.
Therefore, it might be better to check it and directly return -ENOMEM
without releasing data manually if fails, because the comment of the
devm_kmalloc() says "Memory allocated with this function is
automatically freed on driver detach.".
Affected configurations
• linux linux kernel (>= 5.1 < 5.4.189)
• linux linux kernel (>= 5.5 < 5.10.110)
• linux linux kernel (>= 5.11 < 5.15.33)
• linux linux kernel (>= 5.16 < 5.16.19)
• linux linux kernel (>= 5.17 < 5.17.2)
