CVE-2026-89489

CVE-2026-89489 affects the Linux kernel on the openrisc (or1k) architecture. The sys_or1k_atomic() syscall (number 244) swaps two user-supplied words via hand-written assembly without validating the pointers with access_ok() and without exception table entries for the four memory accesses. An unp...
