In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: wcd937x: set the comp soundwire port correctly For some reason we endup with setting soundwire port for HPHL_COMP and HPHR_COMP as zero, this can potentially result in a memory corruption due to accessing and setting -1 th element of port_map array.
AI Analysis
Technical Summary
The Linux kernel contained a vulnerability in the ASoC codec driver for wcd937x where the soundwire port for HPHL_COMP and HPHR_COMP was incorrectly set to zero. This misconfiguration could cause the driver to access and set the -1th element of the port_map array, resulting in memory corruption. This vulnerability has been resolved in the Linux kernel. The CVSS 3.1 vector indicates local attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.
Potential Impact
Exploitation of this vulnerability could lead to memory corruption within the Linux kernel's audio subsystem, potentially allowing an attacker with local access and limited privileges to compromise system confidentiality, integrity, and availability. No known exploits are reported in the wild at this time.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel. Users and administrators should apply the official kernel updates containing this fix once available. Patch status is not explicitly confirmed in the provided data; therefore, verify the vendor advisory or Linux kernel release notes for the exact fixed versions and apply updates accordingly.
