CVE-2023-53729
In the Linux kernel, the following vulnerability has been resolved: soc: qcom: qmi_encdec: Restrict string length in decode The QMI TLV value for strings in a lot of qmi element info structures account for null terminated strings with MAX_LEN + 1.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: soc: qcom: qmi_encdec: Restrict string length in decode The QMI TLV value for strings in a lot of qmi element info structures account for null terminated strings with MAX_LEN + 1. If a string is actually MAX_LEN + 1 length, this will cause an out of bounds access when the NULL character is appended in decoding.
