CVE-2026-43242 Details
Description
In the Linux kernel, the following vulnerability has been resolved: soc: ti: k3-socinfo: Fix regmap leak on probe failure The mmio regmap allocated during probe is never freed. Switch to using the device managed allocator so that the regmap is released on probe failures (e.g. probe deferral) and on driver unbind.
A vulnerability exists in the Linux kernel's K3 SOC information driver, where the MMIO regmap allocated during the probe process is not properly freed. This can lead to a resource leak, as the allocated regmap remains in memory and is not released back to the system. The issue arises because the driver does not use the device-managed allocator, which would automatically free the regmap on probe failures or when the driver is unbound. The vulnerability affects several versions of the Linux kernel.
The vulnerability has been addressed by modifying the driver to use the device-managed regmap allocator, which automatically frees the regmap on probe failures and when the driver is unbound. Users can apply the latest patches available in the Linux kernel stable tree to mitigate this issue.
