CVE-2024-27003

In the Linux kernel, the following vulnerability has been resolved: clk: Get runtime PM before walking tree for clksummary Similar to the previous commit, we should make sure that all devices are runtime resumed before printing the clksummary through debugfs. Failure to do so would result in a...

CVE-2024-27003

CVE-2024-27003 affects the Linux kernel clock framework. The issue arises when printing clk_state via debugfs without proper runtime PM synchronization, risking deadlock if a thread resuming a device also resumes in another thread. The fix removes the now-superfluous clk_pm_runtime_get/put calls ...

kernel: soundwire: bus: Fix unbalanced pm_runtime_put() causing usage count underflow

A reference count underflow flaw was found in the Linux kernel's SoundWire bus driver. When pmruntimeresumeandget returns an error -EACCES, the code continues execution and calls pmruntimeput at the end, even though the usage count was never incremented. This causes a usage count underflow in the...
