Official description
In the Linux kernel, the following vulnerability has been resolved:
accel: ethosu: Ensure SRAM size is 0 on mapping failure
On a mapping failure of the SRAM, the SRAM size is left as non-zero. The probe will succeed as the error return is not checked since having SRAM is not a hard requirement. The non-zero size allows jobs to access SRAM which is left pointing to physical base address 0x0.
