CVE-2026-99259
soc/tegra: pmc: Fix uninitialised clock rate
In the Linux kernel, the following vulnerability has been resolved: soc/tegra: pmc: Fix uninitialised clock rate For legacy 32-bit Tegra devices, the warning in the tegra_pmc_enter_suspend_mode() function is being triggered because the early_pmc->rate variable is never configured and hence, always 0. This issue started occurring after updating the PMC driver to create the PMC context dynamically which causes the 'rate' to be set in the new dynamic context, but missed updating the rate in the early PMC context. Fix this by initialising the early_pmc->rate variable for 32-bit Tegra devices when the rate for the PMC context is initialised. [[email protected]: move assignment to existing #ifdef block]
