CVE-2023-53465 | soundwire: qcom: fix storing port config out-of-bounds

In the Linux kernel, the following vulnerability has been resolved: soundwire: qcom: fix storing port config out-of-bounds The 'qcom_swrm_ctrl->pconfig' has size of QCOM_SDW_MAX_PORTS (14), however we index it starting from 1, not 0, to match real port numbers. This can lead to writing port config past 'pconfig' bounds and overwriting next member of 'qcom_swrm_ctrl' struct. Reported also by smatch: drivers/soundwire/qcom.c:1269 qcom_swrm_get_port_config() error: buffer overflow 'ctrl->pconfig' 14 <= 14

7.1 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
