What is CVE-2026-53202?
CVE-2026-53202 is a high-severity vulnerability in Linux kernel, published on 25 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Fix signed integer truncation in IPC receive
Fix potential buffer overflow where firmware-supplied data_size is cast to signed int before being used in min_t(). Large unsigned values (>= 0x80000000) become negative, causing unsigned wraparound and oversized memcpy operations that can overflow the stack buffer.
Change min_t(int, ...) to min() as both values are unsigned and can be handled by min() without explicit cast.
Which versions are affected by CVE-2026-53202?
It affects 1 product.
Products include Linux kernel.
How do I fix CVE-2026-53202?
Apply the vendor's patch.
Is CVE-2026-53202 being exploited?
There is no known exploitation of CVE-2026-53202 in the wild and no public exploit code.
