CVE-2026-97912— accel: ethosu: Ensure SRAM size is 0 on mapping failure

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: 在映射失败时将 SRAM 大小设置为 0 当 SRAM 映射失败时，SRAM 的大小未被清零，仍保留为非零值。由于 SRAM 并非必需功能，且探针（probe）未检查错误返回值，导致探针仍会成功返回。然而，非零的 SRAM 大小会允许作业访问 SRAM，而此时 SRAM 的指针仍指向物理基地址 0x0，从而引发潜在的安全或稳定性问题。

Vulnerability Title
accel: ethosu: Ensure SRAM size is 0 on mapping failure
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: accel: ethosu: Ensure SRAM size is 0 on mapping failure On a mapping failure of the SRAM, the SRAM size is left as non-zero. The probe will succeed as the error return is not checked since having SRAM is not a hard requirement. The non-zero size allows jobs to access SRAM which is left pointing to physical base address 0x0.
