The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Affected versions of this package are vulnerable to Out-of-bounds Read due to insufficient validation in the sdei_interrupt_bind function of the parameter in register x1. This parameter is then passed to a call to plat_ic_get_interrupt_type, allowing it to be any arbitrary value that passes checks in the plat_ic_is_sgi function. A compromised Normal World (Linux kernel) can enable a root-privileged attacker to issue arbitrary SMC calls, controlling 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). Although the read value is never returned to non-secure memory or in registers, preventing a leak, an attacker can still crash TF-A.
