CVE-2022-49993

CVE-2022-49993 affects the Linux kernel loop subsystem. The vulnerability stems from overflow when configuring a loop via ioctl: the code copies info->lo_offset (loop_info64) into lo_offset (loff_t), enabling an overflow that can trigger a warning in iomap_iter() (via iomap_iter_done). The iss...

Tech-ASan: Two-Stage Check for Address Sanitizer

Address Sanitizer ASan is a sharp weapon for detecting memory safety violations, including temporal and spatial errors hidden in C/C++ programs during execution. However, ASan incurs significant runtime overhead, which limits its efficiency in testing large software. The overhead mainly comes fro...
