Summary
Fix critical severity security issue in
lsdriver/physical.h.Vulnerability
V-018lsdriver/physical.h:219Description: The lsdriver kernel module exposes direct physical memory read and write operations to any user who can open the device node. The write operation at physical.h:250 allows writing attacker-controlled data to any physical memory address. Without access restrictions on the device node, a non-root Android user can overwrite kernel security structures such as process credentials (task_struct->cred) or SELinux enforcement flags, granting themselves immediate root privileges without exploiting any memory corruption bug.
