CVE-2026-97915— accel/ivpu: Limit firmware log name prints to field size

Quick assessment

Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： accel/ivpu：限制固件日志名称打印的字段长度 struct vpu_tracing_buffer_header 中的 name 字段是一个固定大小的数组，由 NPU（神经网络处理单元）固件填充。该字段预期以 NUL 结尾，但主机端并未对此进行强制校验。因此，若该 NUL 终止符缺失，使用无边界字符串转换进行打印将越界读取，并通过 dmesg 和 debugfs 固件日志输出暴露共享追踪缓冲区对象（BO）中相邻的内存字节。 本修复措施限制打印的字符数不超过 nam

Vulnerability Title
accel/ivpu: Limit firmware log name prints to field size
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Limit firmware log name prints to field size The name in struct vpu_tracing_buffer_header is a fixed-size array populated by the NPU firmware. It is expected to be NUL-terminated, but nothing on the host side enforces this, so printing it with an unbounded string conversion would read past the field if the terminator is ever missing and expose adjacent bytes of the shared tracing BO through dmesg and the debugfs FW log output. Print at most as many characters as the name field holds, so the output never runs past it even if the string is not NUL-terminated.
