CVE-2026-80776

CVE-2026-80776 is a race condition in the Linux kernel futex subsystem, specifically in futex_pivot_pending() during a custom private hash resize. Because futex_pivot_pending() reads the hash_new and hash fields without serialization, a resize task can observe a pre-pivot hash_new alongside a pos...

CVE-2026-80758

CVE-2026-80758 is a use-after-free vulnerability in the Linux kernel's futex subsystem. The flaw is in futex_private_hash_put(), which drops its reference to the private hash (fph) before evaluating fph->mm for wake_up_var(). Because futex_ref_put() re-enables preemption before returning, a ta...
