CVE-2026-23124

CVE-2026-23124 is a Linux kernel IPv6 data-race issue in ndisc_router_discovery() where reads/writes to in6_dev->ra_mtu occur without proper synchronization. The race can occur during router advertisement MTU handling (mtu checks are noted but not yet enforced); the fix adds READ_ONCE()/WRITE_...

CVE-2026-23124: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ipv6: annotate data-race in ndiscrouterdiscovery syzbot found that ndiscrouterdiscovery could read and write in6dev-ramtu without holding a lock 1 This looks fine, IFLAINET6RAMTU is best effort. Add READONCE/WRITEONCE to document...
