In the Linux kernel, the following vulnerability has been resolved:

soc/tegra: cbb: Fix cross-fabric target timeout lookup

When a fabric receives an error interrupt, the error may have
occurred on a different fabric. The target timeout lookup was using
the wrong base address (cbb->regs) with offsets from a different
fabric's target map, causing a kernel page fault.

Unable to handle kernel paging request at virtual address ffff80000954cc00
pc : tegra234_cbb_get_tmo_slv+0xc/0x28
Call trace:
tegra234_cbb_get_tmo_slv+0xc/0x28
print_err_notifier+0x6c0/0x7d0
tegra234_cbb_isr+0xe4/0x1b4

Add tegra234_cbb_get_fabric() to look up the correct fabric device
using fab_id, and use its base address for accessing target timeout
registers.
