Threats Tagged 'cve-2025-39751'

A security advisory from Red Hat addresses multiple vulnerabilities in the Linux kernel packages for Red Hat Enterprise Linux 10 and related products. The update fixes issues including race conditions, buffer overflows, use-after-free, and validation errors across various kernel subsystems such as NFS, vsock/virtio, IPv6, ALSA audio, and others. The advisory rates the overall impact as moderate and requires a system reboot after applying the update.

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: HID: core: Harden s32ton() against conversion to 0 bits (CVE-2025-38556) * kernel: sctp: linearize cloned gso packets in sctp_rcv (CVE-2025-38718) * kernel: tls: fix handling of zero-length records on the rx_list (CVE-2025-39682) * kernel: ALSA: hda/ca0132: Fix buffer overflow in add_tuning_control (CVE-2025-39751) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * kernel: HID: core: Harden s32ton() against conversion to 0 bits (CVE-2025-38556) * kernel: sctp: linearize cloned gso packets in sctp_rcv (CVE-2025-38718) * kernel: tls: fix handling of zero-length records on the rx_list (CVE-2025-39682) * kernel: ALSA: hda/ca0132: Fix buffer overflow in add_tuning_control (CVE-2025-39751) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Multiple security vulnerabilities affecting the Linux kernel in Red Hat Enterprise Linux 10 and related distributions have been identified and fixed. These include race conditions, buffer overflows, and improper bounds checking in kernel subsystems such as NFS, vsock/virtio, memory management, ALSA audio, and WiFi. The update addresses these issues to improve system security and stability. A system reboot is required after applying the update for changes to take effect.
