Moderate: kernel security update

Open Source Vulnerabilities ALSA-2026:2212

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: net: openvswitch: fix nested key length validation in the set() action (CVE-2025-37789) * kernel: Linux kernel: irqchip/gic-v2m use-after-free vulnerability (CVE-2025-37819) * kernel: RDMA/core: Fix "KASAN: slab-use-after-free Read in ib_register_device" problem (CVE-2025-38022) * kernel: Linux kernel: RDMA/rxe use-after-free vulnerability leading to potential arbitrary code execution (CVE-2025-38024) * kernel: Linux kernel: Memory corruption in Squashfs due to incorrect block size calculation (CVE-2025-38415) * kernel: vsock/vmci: Clear the vmci transport packet properly when initializing it (CVE-2025-38403) * kernel: Linux kernel: Denial of Service in ATM CLIP module via infinite recursion (CVE-2025-38459) * kernel: Linux kernel: Data corruption and system instability due to improper io_uring/net buffer handling (CVE-2025-38730) * kernel: Linux kernel: Denial of Service via out-of-bounds read in USB configuration parsing (CVE-2025-39760) * kernel: net: use dst_dev_rcu() in sk_setup_caps() (CVE-2025-40170) * kernel: ipv6: use RCU in ip6_xmit() (CVE-2025-40135) * kernel: Bluetooth: ISO: Fix possible UAF on iso_conn_free (CVE-2025-40141) * kernel: ipv6: use RCU in ip6_output() (CVE-2025-40158) * kernel: Linux kernel: Use-after-free in proc_readdir_de() can lead to privilege escalation or denial of service. (CVE-2025-40271) * kernel: Linux kernel ALSA USB audio driver: Buffer overflow leading to information disclosure and denial of service (CVE-2025-40269) * kernel: Bluetooth: hci_sync: fix race in hci_cmd_sync_dequeue_once (CVE-2025-40318) 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.
