AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The fix includes adding NULL pointer checks in the sma1307_setting_loaded() function to prevent kernel crashes. Users should update their Linux kernel to versions including this fix as provided by their distribution vendor, such as the Ubuntu security notice USN-7769-1. No additional mitigation is required beyond applying the official kernel updates.
Description
A vulnerability in the Linux kernel's ASoC sma1307 driver was resolved by adding NULL pointer checks in the sma1307_setting_loaded() function. The issue involved potential NULL pointers from variables allocated by kzalloc and devm_kzalloc, which could lead to improper cleanup and stability issues. This vulnerability was identified through static analysis and fixed in Linux kernel versions after the affected releases. The vulnerability has a medium severity with a CVSS score of 5.5 and does not impact confidentiality or integrity but affects availability. Multiple Linux kernel subsystems, including the ASoC sma1307 driver, were updated in a security patch released by Ubuntu and other vendors. No known exploits are reported in the wild.
