CVE-2025-21748: Linux Azure kernels could corrupt memory on 32-bit systems
CVE-2025-21748 · published 1 year ago
Summary
The Linux kernel used in Canonical's Azure images (versions 5.19, 6.2, 6.5, and 6.8) has a calculation error that can overflow on 32-bit machines, potentially leading to memory corruption. This could cause applications to crash or behave unpredictably. Install the latest kernel updates from your Azure image to apply the fix.

ksmbd: fix integer overflows on 32 bit systems
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.
