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： TPM: st33zp24：在状态读取失败时返回零 函数忽略了传输层读取的结果，即使没有接收到任何字节，仍会返回数据。例如，I2C 传输层在寄存器选择写入过短或失败时会跳过 ，导致 变量未被初始化。由此产生的栈上残留值可能被解释为 TPM 状态标志（TPM_STS flags），从而让状态检查错误地通过。 由于状态回调函数无法向上传播传输层错误，因此修复方案是：除非 报告恰好接收到一个字节，否则返回零。当没有任何状态位被置位时，调用方将进入重试流程或现有的超时/错误处理路径

Vulnerability Title
tpm: st33zp24: Return zero on status read failure
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: tpm: st33zp24: Return zero on status read failure st33zp24_status() ignores the result of the transport read and returns data even when no byte was received. The I2C transport, for example, skips i2c_master_recv() when the register-select write is short or fails, leaving data uninitialized. The resulting stack value can be interpreted as TPM_STS flags and let status checks complete spuriously. The status callback cannot propagate a transport error. Return zero unless recv() reports exactly one byte. With no status bits set, callers retry or take their existing timeout or error path instead of acting on an invalid status value. This issue was found by a static analysis checker and confirmed by manual source review.
