Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： crypto: keembay - 修复错误处理路径中 AEAD 注销计数的错误 函数在注册 skcipher（对称密钥流密码）算法之前，会先注册 AEAD（认证加密）算法。如果 skcipher 算法注册失败，该函数会调用 来回滚之前已注册的 AEAD 算法，但它传入的参数是 ，即 skcipher 算法表的大小。 在 AEAD 回滚路径中应使用 ，以确保注销辅助函数遍历的是与注册时相同的 AEAD 算法表。同时，对附近的注释进行了澄清：内核的加密注册辅助函数会自动清

Vulnerability Title
crypto: keembay - Fix AEAD unregister count in error path
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: crypto: keembay - Fix AEAD unregister count in error path register_aes_algs() registers the AEAD algorithms before registering the skcipher algorithms. If skcipher registration fails, the function unwinds the earlier AEAD registration with crypto_engine_unregister_aeads(), but it passes ARRAY_SIZE(algs), which is the skcipher table size. Use ARRAY_SIZE(algs_aead) for the AEAD unwind path so the unregister helper iterates over the same table that was registered. Also clarify the nearby comment: the crypto registration helpers clean up algorithms registered within the same call, while this function must still unwind earlier successful registration steps.
