CVE-2026-89489: In the Linux kernel, the following vulnerability vulnerability

In the Linux kernel, the following vulnerability has been resolved: openrisc: fix arbitrary kernel memory access via or1k_atomic syscall sys_or1k_atomic() (syscall 244 in the "or1k" ABI) takes two user pointers, v1 and v2, and swaps the words they point to in hand-written assembly. A security weakness in the Linux kernel, the following vulnerability is being tracked as CVE-2026-89489. For an organization using the Linux kernel, the following vulnerability, the next step is to identify affected versions, map where the vulnerable function is reachable and understand what the affected process can access. The important point is that running an affected version of the Linux kernel, the following vulnerability creates exposure, while an actual compromise still depends on whether the attacker can reach the trigger conditions described above. The four memory accesses als.
