CVE-2026-53310

Estado: AnalizadaMedia (5.5)—

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.

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.
