CVE-2026-53310

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> soc/tegra: cbb: Fix cross-fabric target timeout lookup<br /> <br /> When a fabric receives an error interrupt, the error may have<br /> occurred on a different fabric. The target timeout lookup was using<br /> the wrong base address (cbb-&gt;regs) with offsets from a different<br /> fabric&amp;#39;s target map, causing a kernel page fault.<br /> <br /> Unable to handle kernel paging request at virtual address ffff80000954cc00<br /> pc : tegra234_cbb_get_tmo_slv+0xc/0x28<br /> Call trace:<br /> tegra234_cbb_get_tmo_slv+0xc/0x28<br /> print_err_notifier+0x6c0/0x7d0<br /> tegra234_cbb_isr+0xe4/0x1b4<br /> <br /> Add tegra234_cbb_get_fabric() to look up the correct fabric device<br /> using fab_id, and use its base address for accessing target timeout<br /> registers.
