24 Dec 2025 — In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_conn: return ERR_PTR instead of NULL when there is no link hci_connect_sco currently returns NULL when there is no link (i.e. when hci_conn_link() returns NULL). sco_connect() expects an ERR_PTR in case of any error (see line 266 in sco.c). Thus, hcon set as NULL passes through to sco_conn_add(), which tries to get hcon->hdev, resulting in dereferencing a NULL pointer as reported by syzkaller. The same issue exists for iso_co... • https://git.kernel.org/stable/c/06149746e7203d5ffe2d6faf9799ee36203aa8b8 •

24 Dec 2025 — In the Linux kernel, the following vulnerability has been resolved: ice: prevent NULL pointer deref during reload Calling ethtool during reload can lead to call trace, because VSI isn't configured for some time, but netdev is alive. To fix it add rtnl lock for VSI deconfig and config. Set ::num_q_vectors to 0 after freeing and add a check for ::tx/rx_rings in ring related ethtool ops.

24 Dec 2025 — In the Linux kernel, the following vulnerability has been resolved: vdpa: Add queue index attr to vdpa_nl_policy for nlattr length check The vdpa_nl_policy structure is used to validate the nlattr when parsing the incoming nlmsg. It will ensure the attribute being described produces a valid nlattr pointer in info->attrs before entering into each handler in vdpa_nl_ops. That is to say, the missing part in vdpa_nl_policy may lead to illegal nlattr after parsing, which could lead to OOB read just like CVE-2023... • https://git.kernel.org/stable/c/13b00b135665c92065a27c0c39dd97e0f380bd4f •
