CVE-2025-21748
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix integer overflows on 32 bit systems On 32bit systems the addition operations in ipc_msg_alloc() can potentially overflow leading to memory corruption.
Does this matter?
Lower severity and a low EPSS score (0.59%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix integer overflows on 32 bit systems On 32bit systems the addition operations in ipc_msg_alloc() can potentially overflow leading to memory corruption. Add bounds checking using KSMBD_IPC_MAX_PAYLOAD to avoid overflow.
