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.
