Description
In the Linux kernel, the following vulnerability has been resolved:
spi: fix statistics allocation
The controller per-cpu statistics is not allocated until after the
controller has been registered with driver core, which leaves a window
where accessing the sysfs attributes can trigger a NULL-pointer
dereference.
Fix this by moving the statistics allocation to controller allocation
while tying its lifetime to that of the controller (rather than using
implicit devres).
Affected configurations
• linux linux kernel (>= 6.0 < 6.1.167)
• linux linux kernel (>= 6.2 < 6.6.130)
• linux linux kernel (>= 6.7 < 6.12.78)
