CVE-2026-53310
soc/tegra: cbb: Fix cross-fabric target timeout lookup
Description
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.
