[Security Fix]
- lib/timerqueue.c の timerqueue_add() には、タイマーツリーの破損によ
りタスクが起床されない問題があるため、特別なユーザー権限を持つローカル
の攻撃者により、サービス拒否 (システムのスローダウン、ストール) 状態を
引き起こすことが可能となる脆弱性が存在します。 (CVE-2021-20317)
- net/tipc/crypto.c には、透過的プロセス間通信 (TIPC) 機能の
MSG_CRYPTO メッセージタイプに対するユーザーが指定したサイズの検証が不
十分である問題のため、リモートの攻撃者により、TIPC メッセージの送信を
介して、メモリ領域の破壊や特権昇格が可能となる脆弱性が存在します。

CVE:
CVE-2021-20317
A flaw was found in the Linux kernel. A corrupted timer tree caused the task wakeup to be missing in the timerqueue_add function in lib/timerqueue.c. This flaw allows a local attacker with special user privileges to cause a denial of service, slowing and eventually stopping the system while running OSP.

CVE-2021-43267
An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type.
