CVE-2026-89568

A flaw was found in the Linux kernel. The khopreservedmemoryreserve function, responsible for reserving memory, incorrectly calculates the size of these reservations. This issue arises because it uses a 32-bit integer for bit shifting, which limits the maximum reservation size to 2 Gigabytes GiB...
