CVE-2026-89731

This Linux kernel vulnerability affects the CXL RAS subsystem, specifically the cxl_rch_get_aer_info() function. The function reads the RCH Downstream Port AER capability from the RCRB MMIO block using a loop bounded by sizeof(struct aer_capability_regs). Because struct pcie_tlp_log has grown ove...
