Vulnerability from github – Published: 2025-03-12 00:31 – Updated: 2025-03-12 00:31

Details

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.

Severity ?

5.5 (Medium)
