Description
In the Linux kernel, the following vulnerability has been resolved:
soc: bcm: Check for NULL return of devm_kzalloc()
As the potential failure of allocation, devm_kzalloc() may return NULL. Then
the 'pd->pmb' and the follow lines of code may bring null pointer dereference.
Therefore, it is better to check the return value of devm_kzalloc() to avoid
this confusion.
Affected configurations
• linux linux kernel (>= 5.12 < 5.15.46)
• linux linux kernel (>= 5.16 < 5.17.14)
• linux linux kernel (>= 5.18 < 5.18.3)
