Summary
In the Linux kernel, the following vulnerability has been resolved: zram: free secondary algorithms names We need to kfree() secondary algorithms names when reset zram device that had multi-streams, otherwise we leak memory. [senozhatsky@chromium.org: kfree(NULL) is legal] Link: https://lkml.kernel.org/r/20240917013021.868769-1-senozhatsky@chromium.org
