In the Linux kernel, the following vulnerability has been resolved: net: mana: Fix double destroy_workqueue on service rescan PCI path While testing corner cases in the driver, a use-after-free crash was found on the service rescan PCI path. When mana_serv_reset() calls mana_gd_suspend(), mana_gd_cleanup() destroys gc->service_wq. If the subsequent mana_gd_resume() fails with -ETIMEDOUT or -EPROTO, the code falls through to mana_serv_rescan() which triggers pci_stop_and_remove_bus_device(). This invokes the PCI .remove callback (mana_gd_remove), which calls mana_gd_cleanup() a second time, attempting to destroy the already- freed workqueue. Fix this by NULL-checking gc->service_wq in mana_gd_cleanup() and setting it to NULL after destruction.

The remote Ubuntu 24.04 LTS / 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8310-1 advisory.

    It was discovered that the Linux kernel algif_aead module did not properly handle in-place cryptographic     operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or     possibly escape a container. (CVE-2026-31431)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

    - S390 architecture;

    - Cryptographic API;

    - GPU drivers;

    - Ethernet bonding driver;

    - Microsoft Azure Network Adapter (MANA) driver;

    - Network file system (NFS) server daemon;

    - Distributed Switch Architecture;

    - Netfilter;

    - Control group (cgroup);

    - Kernel kexec() syscall;

    - Memory management;

    - MAC80211 subsystem;

    - Multipath TCP;

    - Packet sockets;

    - TLS protocol;

    - Unix domain sockets; (CVE-2025-71088, CVE-2025-71090, CVE-2025-71127, CVE-2025-71134, CVE-2025-71139,     CVE-2025-71141, CVE-2025-71142, CVE-2025-71144, CVE-2025-71152, CVE-2025-71155, CVE-2026-23274,     CVE-2026-23351, CVE-2026-23394, CVE-2026-23454, CVE-2026-31419, CVE-2026-31504, CVE-2026-31533,     CVE-2026-43033, CVE-2026-43077, CVE-2026-43078, CVE-2026-43276)

  - net: mana: Fix double destroy_workqueue on service rescan PCI path While testing corner cases in the     driver, a use-after-free crash was found on the service rescan PCI path. When mana_serv_reset() calls     mana_gd_suspend(), mana_gd_cleanup() destroys gc->service_wq. If the subsequent mana_gd_resume() fails     with -ETIMEDOUT or -EPROTO, the code falls through to mana_serv_rescan() which triggers     pci_stop_and_remove_bus_device(). This invokes the PCI .remove callback (mana_gd_remove), which calls     mana_gd_cleanup() a second time, attempting to destroy the already- freed workqueue. Fix this by NULL-     checking gc->service_wq in mana_gd_cleanup() and setting it to NULL after destruction.
