In the Linux kernel, the following vulnerability has been resolved: rds: tcp: Fix use-after-free of net in reqsk_timer_handler(). syzkaller reported a warning of netns tracker [0] followed by KASAN splat [1] and another ref tracker warning [1]. syzkaller could not find a repro, but in the log, the only suspicious sequence was as follows: 18:26:22 executing program 1: r0 = socket$inet6_mptcp(0xa, 0x1, 0x106) ... connect$inet6(r0, &(0x7f0000000080)={0xa, 0x4001, 0x0, @loopback}, 0x1c) (async) The notable thing here is 0x4001 in connect(), which is RDS_TCP_PORT. So, the scenario would be: 1. unshare(CLONE_NEWNET) creates a per netns tcp listener in rds_tcp_listen_init(). 2. syz-executor connect()s to it and creates a reqsk. 3. syz-executor exit()s immediately. 4. netns is dismantled.

https://notcve.org/view.php?id=CVE-2024-26864
In the Linux kernel, the following vulnerability has been resolved: tcp: Fix refcnt handling in __inet_hash_connect(). syzbot reported a warning in sk_nulls_del_node_init_rcu(). The commit 66b60b0c8c4a ("dccp/tcp: Unhash sk from ehash for tb2 alloc failure after check_estalblished().") tried to fix an issue that an unconnected socket occupies an ehash entry when bhash2 allocation fails. In such a case, we need to revert changes done by check_established(), which does not hold refcnt when inserting socket into ehash. So, to revert the change, we need to __sk_nulls_add_node_rcu() instead of sk_nulls_add_node_rcu(). Otherwise, sock_put() will cause refcnt underflow and leak the socket.

Esto causa el problema anterior. Este parche soluciona el problema al devolver NULL si el encabezado Ethernet no va seguido de una etiqueta HSR. • https://git.kernel.org/stable/c/f266a683a4804dc499efc6c2206ef68efed029d0 https://git.kernel.org/stable/c/e3b2bfb8ff1810a537b2aa55ba906a6743ed120c https://git.kernel.org/stable/c/889ed056eae7fda85b769a9ab33c093379c45428 https://git.kernel.org/stable/c/7fb2d4d6bb1c85f7a23aace0ed6c86a95dea792a https://git.kernel.org/stable/c/a809bbfd0e503351d3051317288a70a4569a4949 https://git.kernel.org/stable/c/1ed222ca7396938eb1ab2d034f1ba0d8b00a7122 https://git.kernel.org/stable/c/39cc316fb3bc5e7c9dc5eed314fe510d119c6862 https://git.kernel.org/stable/c/97d2148ea435dff4b4e71817c9032eb32 • CWE-20: Improper Input Validation •
