CVE-2024-26655 - OpenCVE

In the Linux kernel, the following vulnerability has been resolved: Fix memory leak in posix_clock_open() If the clk ops.open() function returns an error, we don't release the pccontext we allocated for this clock. Re-organize the code slightly to make it all more obvious.
