In the Linux kernel, the following vulnerability has been resolved: x86/apic: Disable x2apic on resume if the kernel expects so When resuming from s2ram, firmware may re-enable x2apic mode, which may have been disabled by the kernel during boot either because it doesn't support IRQ remapping or for other reasons. This causes the kernel to continue using the xapic interface, while the hardware is in x2apic mode, which causes hangs. This happens on defconfig + bare metal + s2ram. Fix this in lapic_resume() by disabling x2apic if the kernel expects it to be disabled, i.e. when x2apic_mode = 0. The ACPI v6.6 spec, Section 16.3 [1] says firmware restores either the pre-sleep configuration or initial boot configuration for each CPU, including MSR state: When executing from the power-on reset vector as a result of waking from an S2 or S3 sleep state, the platform firmware performs only the hardware initialization required to restore the system to either the state the platform was in prior to the initial operating system boot, or to the pre-sleep configuration state. In multiprocessor systems, non-boot processors should be placed in the same state as prior to the initial operating system boot. (further ahead) If this is an S2 or S3 wake, then the platform runtime firmware restores minimum context of the system before jumping to the waking vector. This includes: CPU configuration. Platform runtime firmware restores the pre-sleep configuration or initial boot configuration of each CPU (MSR, MTRR, firmware update, SMBase, and so on). Interrupts must be disabled (for IA-32 processors, disabled by CLI instruction). (and other things) So at least as per the spec, re-enablement of x2apic by the firmware is allowed if "x2apic on" is a part of the initial boot configuration.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For Debian 11 bullseye, these problems have been fixed in version     5.10.257-1.  This version additionally includes many more bug fixes     from stable updates 5.10.252-5.10.257.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to     its security tracker page at:

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - x86/apic: Disable x2apic on resume if the kernel expects so When resuming from s2ram, firmware may re-     enable x2apic mode, which may have been disabled by the kernel during boot either because it doesn't     support IRQ remapping or for other reasons. This causes the kernel to continue using the xapic interface,     while the hardware is in x2apic mode, which causes hangs. This happens on defconfig + bare metal + s2ram.
    Fix this in lapic_resume() by disabling x2apic if the kernel expects it to be disabled, i.e. when     x2apic_mode = 0. The ACPI v6.6 spec, Section 16.3 [1] says firmware restores either the pre-sleep     configuration or initial boot configuration for each CPU, including MSR state: When executing from the     power-on reset vector as a result of waking from an S2 or S3 sleep state, the platform firmware performs     only the hardware initialization required to restore the system to either the state the platform was in     prior to the initial operating system boot, or to the pre-sleep configuration state. In multiprocessor     systems, non-boot processors should be placed in the same state as prior to the initial operating system     boot. (further ahead) If this is an S2 or S3 wake, then the platform runtime firmware restores minimum     context of the system before jumping to the waking vector. This includes: CPU configuration. Platform     runtime firmware restores the pre-sleep configuration or initial boot configuration of each CPU (MSR,     MTRR, firmware update, SMBase, and so on). Interrupts must be disabled (for IA-32 processors, disabled by     CLI instruction). (and other things) So at least as per the spec, re-enablement of x2apic by the firmware     is allowed if x2apic on is a part of the initial boot configuration. [1]     https://uefi.org/specs/ACPI/6.6/16_Waking_and_Sleeping.html#initialization [ bp: Massage. ]     (CVE-2026-43363)

Note that Nessus relies on the presence of the package as reported by the vendor.
