Description OSIDB Bzimport 2024-12-27 14:05:35 UTC 
In the Linux kernel, the following vulnerability has been resolved:

firmware_loader: Fix possible resource leak in fw_log_firmware_info()

The alg instance should be released under the exception path, otherwise
there may be resource leak here.

To mitigate this, free the alg instance with crypto_free_shash when kmalloc
fails.
