WebThe memory for llcc_driv_data is allocated by the LLCC driver. But when it is passed as the private driver info to the EDAC core, it will get freed during the qcom_edac driver release. So when the qcom_edac driver gets probed again, it will try to use the freed data leading to the use-after-free bug. WebA Linux kernel module called EDAC, which stands for error detection and correction, can report ECC memory errors and corrections. EDAC can capture and report error information for hardware errors in the memory or cache, direct memory access (DMA), fabric switches, thermal throttling, HyperTransport bus, and others. higs baseball

Applications that require low latency (such as telephone conversations) cannot use automatic repeat request (ARQ); they must use forward error correction (FEC). By the time an ARQ system discovers an error and re-transmits it, the re-sent data will arrive too late to be usable. Applications where the transmitter immediately forgets the information as soon as it is sent (such as most television cameras) cannot use ARQ; they must use FEC because when an error occur… WebIt provides a very high density, radiation hardened by design (RHBD), non-volatile memory module suitable for many space applications such as geo-stationary missions, Earth observation, navigation, manned space vehicles and deep space scientific exploration.
