Title
ima: Fix potential memory leak in ima_init_crypto()
Summary
In the Linux kernel, the following vulnerability has been resolved: ima: Fix potential memory leak in ima_init_crypto() On failure to allocate the SHA1 tfm, IMA fails to initialize and exits without freeing the ima_algo_array. Add the missing kfree() for ima_algo_array to avoid the potential memory leak.
