CVE-2024-43849 Details
Description
In the Linux kernel, the following vulnerability has been resolved: soc: qcom: pdr: protect locator_addr with the main mutex If the service locator server is restarted fast enough, the PDR can rewrite locator_addr fields concurrently. Protect them by placing modification of those fields under the main pdr->lock.
A vulnerability exists in the Linux kernel's handling of the locator address for the Protection Domain Restart (PDR) service on Qualcomm System on Chips (SOCs). When the service locator server is restarted rapidly, it can lead to a race condition where the PDR overwrites locator address fields simultaneously, potentially causing inconsistencies. This issue has been addressed by modifying the PDR locator address fields under the main PDR lock, ensuring that changes are synchronized and preventing concurrent write operations.
Users can upgrade to the latest version of the Linux kernel available in the Debian repositories. For systems running Debian 11, the updated kernel version is 5.10.226-1. Instructions for installing the updated kernel can be found on the Debian LTS website.
