Description
In the Linux kernel, the following vulnerability has been resolved:
parisc: BTLB: Fix crash when setting up BTLB at CPU bringup
When using hotplug and bringing up a 32-bit CPU, ask the firmware about the
BTLB information to set up the static (block) TLB entries.
For that write access to the static btlb_info struct is needed, but
since it is marked __ro_after_init the kernel segfaults with missing
write permissions.
Fix the crash by dropping the __ro_after_init annotation.
Affected configurations
• linux linux kernel (>= 6.6 < 6.6.18)
• linux linux kernel (>= 6.7 < 6.7.6)
• linux linux kernel 6.8
