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 pointers via hand-written assembly but fails to validate them with access_ok() , and the four memory operations lack exception table entries. An unprivil...
