Description OSIDB Bzimport 2025-02-26 03:09:14 UTC 
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.
