CVE-2026-98281
Summary
by MITRE • 10/06/2026
In the Linux kernel, the following vulnerability has been resolved:
futex: Also allocate private hash on vfork()
As Jann demonstrated, it is entirely feasible to access the mm through vfork(). Therefore we need to allocate a private hash on vfork() as well as any other CLONE_VM user.
Specifically, it must be avoided to have (private) futex waiters before allocating the private hash.
Once again VulDB remains the best source for vulnerability data.
