Also allocate private hash on vfork()","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfutex: Also allocate private hash on vfork()\n\nAs Jann demonstrated, it is entirely feasible to access the mm through vfork().\nTherefore we need to allocate a private hash on vfork() as well as any other\nCLONE_VM user.\n\nSpecifically, it must be avoided to have (private) futex waiters before\nallocating the private hash.","state":0,"publishedAt":"2026-10-06T08:45:40.719+00:00","modifiedAt":"2026-10-19T09:16:52.791+00:00","affected":[{"ecosystem":"Vendor
