AI-suggested
A patch is available and has been released by the vendor. Users should update their Linux kernel to the fixed versions listed in the Ubuntu security advisories and reboot their systems to apply the fixes. Due to an ABI change, recompilation and reinstallation of third-party kernel modules may be required. Follow the vendor's update instructions carefully.
Description
A double-free vulnerability was identified and fixed in the Linux kernel's spi-sprd-adi driver. The issue arises from improper handling of the spi_controller structure during error paths in the probe function, leading to a double free of memory. This flaw could potentially cause system instability or crashes. The vulnerability has a CVSS score of 7.8, indicating a high severity impact on confidentiality, integrity, and availability. A patch is available and included in updated Linux kernel versions. Users are advised to update to the fixed versions and reboot to apply the changes.
