| Subject: CVE-2024-56690: crypto: pcrypt - Call crypto layer directly when padata_do_parallel() return -EBUSY |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| crypto: pcrypt - Call crypto layer directly when padata_do_parallel() return -EBUSY |
| |
| Since commit 8f4f68e788c3 ("crypto: pcrypt - Fix hungtask for |
| PADATA_RESET"), the pcrypt encryption and decryption operations return |
| -EAGAIN when the CPU goes online or offline. In alg_test(), a WARN is |
| generated when pcrypt_aead_decrypt() or pcrypt_aead_encrypt() returns |
| -EAGAIN, the unnecessary panic will occur when panic_on_warn set 1. |
| Fix this issue by calling crypto layer directly without parallelization |
| in that case. |
| |
| The Linux kernel CVE team has assigned CVE-2024-56690 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
