| CVE-2025-68187 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: net: mdio: Check regmap pointer returned by device_node_to_regmap() The call to device_node_to_regmap() in airoha_mdio_probe() can return an ERR_PTR() if regmap initialization fails. Currently, the driver stores the pointer without validation, which could lead to a crash if it is later dereferenced. Add an IS_ERR() check and return the corresponding error code to make the probe path more robust. | ||||
| CVE-2023-53745 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: um: vector: Fix memory leak in vector_config If the return value of the uml_parse_vector_ifspec function is NULL, we should call kfree(params) to prevent memory leak. | ||||
| CVE-2025-61667 | 2 Datadoghq, Linux | 2 Agent, Linux | 2026-04-15 | 7.3 High |
| The Datadog Agent collects events and metrics from hosts and sends them to Datadog. A vulnerability within the Datadog Linux Host Agent versions 7.65.0 through 7.70.2 exists due to insufficient permissions being set on the `opt/datadog-agent/python-scripts/__pycache__` directory during installation. Code in this directory is only run by the Agent during Agent install/upgrades. This could allow an attacker with local access to modify files in this directory, which would then subsequently be run when the Agent is upgraded, resulting in local privilege escalation. This issue requires local access to the host and a valid low privilege account to be vulnerable. Note that this vulnerability only impacts the Linux Host Agent. Other variations of the Agent including the container, kubernetes, windows host and other agents are not impacted. Version 7.71.0 contains a patch for the issue. | ||||
| CVE-2022-50722 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: media: ipu3-imgu: Fix NULL pointer dereference in active selection access What the IMGU driver did was that it first acquired the pointers to active and try V4L2 subdev state, and only then figured out which one to use. The problem with that approach and a later patch (see Fixes: tag) is that as sd_state argument to v4l2_subdev_get_try_crop() et al is NULL, there is now an attempt to dereference that. Fix this. Also rewrap lines a little. | ||||
| CVE-2025-68191 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: udp_tunnel: use netdev_warn() instead of netdev_WARN() netdev_WARN() uses WARN/WARN_ON to print a backtrace along with file and line information. In this case, udp_tunnel_nic_register() returning an error is just a failed operation, not a kernel bug. udp_tunnel_nic_register() can fail due to a memory allocation failure (kzalloc() or udp_tunnel_nic_alloc()). This is a normal runtime error and not a kernel bug. Replace netdev_WARN() with netdev_warn() accordingly. | ||||
| CVE-2022-50714 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921e: fix rmmod crash in driver reload test In insmod/rmmod stress test, the following crash dump shows up immediately. The problem is caused by missing mt76_dev in mt7921_pci_remove(). We should make sure the drvdata is ready before probe() finished.

| CVE-2025-68216 | 1 Linux | 1 Linux Kernel | 2026-04-15 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Disable trampoline for kernel module function trace The current LoongArch BPF trampoline implementation is incompatible with tracing functions in kernel modules. This causes several severe and user-visible problems: * The `bpf_selftests/module_attach` test fails consistently. * Kernel lockup when a BPF program is attached to a module function [1]. * Critical kernel modules like WireGuard experience traffic disruption when their functions are traced with fentry [2]. Given the severity and the potential for other unknown side-effects, it is safest to disable the feature entirely for now. This patch prevents the BPF subsystem from allowing trampoline attachments to kernel module functions on LoongArch. This is a temporary mitigation until the core issues in the trampoline code for kernel module handling can be identified and fixed.

| In the Linux kernel, the following vulnerability has been resolved: net/ieee802154: don't warn zero-sized raw_sendmsg() syzbot is hitting skb_assert_len() warning at __dev_queue_xmit() [1], for PF_IEEE802154 socket's zero-sized raw_sendmsg() request is hitting __dev_queue_xmit() with skb->len == 0. Since PF_IEEE802154 socket's zero-sized raw_sendmsg() request was able to return 0, don't call __dev_queue_xmit() if packet length is 0. ---------- #include <sys/socket.h> #include <netinet/in.h> int main(int argc, char *argv[]) { struct sockaddr_in addr = { .sin_family = AF_INET, .sin_addr.s_addr = htonl(INADDR_LOOPBACK) }; struct iovec iov = { }; struct msghdr hdr = { .msg_name = &addr, .msg_namelen = sizeof(addr), .msg_iov = &iov, .msg_iovlen = 1 }; sendmsg(socket(PF_IEEE802154, SOCK_RAW, 0), &hdr, 0); return 0; } ---------- Note that this might be a sign that commit fd1894224407c484 ("bpf: Don't redirect packets with invalid pkt_len") should be reverted, for skb->len == 0 was acceptable for at least PF_IEEE802154 socket. | ||||

| In the Linux kernel, the following vulnerability has been resolved: mptcp: Fix proto fallback detection with BPF The sockmap feature allows bpf syscall from userspace, or based on bpf sockops, replacing the sk_prot of sockets during protocol stack processing with sockmap's custom read/write interfaces. ''' tcp_rcv_state_process() syn_recv_sock()/subflow_syn_recv_sock() tcp_init_transfer(BPF_SOCK_OPS_PASSIVE_ESTABLISHED_CB) bpf_skops_established <== sockops bpf_sock_map_update(sk) <== call bpf helper tcp_bpf_update_proto() <== update sk_prot ''' When the server has MPTCP enabled but the client sends a TCP SYN without MPTCP, subflow_syn_recv_sock() performs a fallback on the subflow, replacing the subflow sk's sk_prot with the native sk_prot. ''' subflow_syn_recv_sock() subflow_ulp_fallback() subflow_drop_ctx() mptcp_subflow_ops_undo_override() ''' Then, this subflow can be normally used by sockmap, which replaces the native sk_prot with sockmap's custom sk_prot. The issue occurs when the user executes accept::mptcp_stream_accept::mptcp_fallback_tcp_ops(). Here, it uses sk->sk_prot to compare with the native sk_prot, but this is incorrect when sockmap is used, as we may incorrectly set sk->sk_socket->ops. This fix uses the more generic sk_family for the comparison instead. Additionally, this also prevents a WARNING from occurring: result from ./scripts/decode_stacktrace.sh: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 337 at net/mptcp/protocol.c:68 mptcp_stream_accept \ (net/mptcp/protocol.c:4005) Modules linked in: ...
