CVE-2026-97911— accel: ethosu: Ensure SRAM region size matches job

Quick assessment

Affected
Linux Linux
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，已修复以下漏洞： accel: ethosu：确保 SRAM 区域大小与作业要求一致 用户空间有可能将作业的 SRAM 大小设置为 0，但在命令流中仍发起 SRAM 访问操作。当作业 SRAM 大小设置为 0 时，系统会跳过设置区域基址寄存器的步骤，从而导致使用先前作业遗留的过时基址。 应使用作业的实际 SRAM 大小来校验区域大小，而非仅校验 SRAM 的总大小。（注：作业的 SRAM 大小此前已针对 SRAM 总大小进行了检查。）

Vulnerability Title
accel: ethosu: Ensure SRAM region size matches job
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: accel: ethosu: Ensure SRAM region size matches job It is possible for userspace to set the job SRAM size to 0, but then still have SRAM accesses in the command stream. When the job SRAM size is 0, setting the region base register is skipped and a stale base address from a prior job is used. Check the region size against the job's SRAM size instead of just the size of the SRAM. The job's SRAM size was already checked against the total SRAM size.
