Trusted Firmware-A (TF-A) before 2.10 has a potential read out-of-bounds in the SDEI service. The input parameter passed in register x1 is not validated well enough in the function sdei_interrupt_bind. The parameter is passed to a call to plat_ic_get_interrupt_type. It can be any arbitrary value passing checks in the function plat_ic_is_sgi. A compromised Normal World (Linux kernel) can enable a root-privileged attacker to issue arbitrary SMC calls. Using this primitive, he can control the content of registers x0 through x6, which are used to send parameters to TF-A. Out-of-bounds addresses can be read in the context of TF-A (EL3). Because the read value is never returned to non-secure memory or in registers, no leak is possible. An attacker can still crash TF-A, however.", "creation_timestamp": "2024-02-22T19:31:11.000000Z"}
