CVE-2026-53310 Details
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.
A vulnerability in the Linux kernel's handling of cross-fabric target timeouts for Tegra SoC can lead to a kernel page fault. This issue arises when a fabric receives an error interrupt that originated in a different fabric. The target timeout lookup incorrectly uses the base address from the current fabric's target map, causing a page fault when accessing the timeout registers. The vulnerability affects the stable version of the Linux kernel.
Users can apply the latest patch available in the Linux kernel stable tree to address this vulnerability.
