CVE-2026-53202: accel/ivpu: Fix signed integer truncation in IPC receive

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.15% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 2821bf2b79e47f87e1dbdd9d25c78240965a97d6, 45cb105b8642c65e9be286f7058e92314efe7ea3, 4788556d4dd9d717037e385de178974e9649231d.

Low priority for now. Upgrade to Linux Linux 2821bf2b79e47f87e1dbdd9d25c78240965a97d6, 45cb105b8642c65e9be286f7058e92314efe7ea3, 4788556d4dd9d717037e385de178974e9649231d or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
