CVE-2023-6535

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: idxd: Let probe fail when workqueue cannot be enabled

The workqueue is enabled when the appropriate driver is loaded and disabled when the driver is removed. When the driver is removed it assumes that the workqueue was enabled successfully and proceeds to free allocations made during workqueue enabling.

Failure during workqueue enabling does not prevent the driver from being loaded. This is because the error path within drv_enable_wq() returns success unless a second failure is encountered during the error path. By returning success it is possible to load the driver even if the workqueue cannot be enabled and allocations that do not exist are attempted to be freed during driver remove.

Some examples of problematic flows: (a)

idxd_dmaengine_drv_probe() -> drv_enable_wq() -> idxd_wq_request_irq(): In above flow, if idxd_wq_request_irq() fails then idxd_wq_unmap_portal() is called on error exit path, but drv_enable_wq() returns 0 because idxd_wq_disable() succeeds. The driver is thus loaded successfully.

idxd_dmaengine_drv_remove()->drv_disable_wq()->idxd_wq_unmap_portal() Above flow on driver unload triggers the WARN in devm_iounmap() because the device resource has already been removed during error path of drv_enable_wq().

(b)

idxd_dmaengine_drv_probe() -> drv_enable_wq() -> idxd_wq_request_irq(): In above flow, if idxd_wq_request_irq() fails then idxd_wq_init_percpu_ref() is never called to initialize the percpu counter, yet the driver loads successfully because drv_enable_wq() returns 0.

idxd_dmaengine_drv_remove()->__idxd_wq_quiesce()->percpu_ref_kill(): Above flow on driver unload triggers a BUG when attempting to drop the initial ref of the uninitialized percpu ref: BUG: kernel NULL pointer dereference, address: 0000000000000010

Fix the drv_enable_wq() error path by returning the original error that indicates failure of workqueue enabling. This ensures that the probe fails when an error is encountered and the driver remove paths are only attempted when the workqueue was enabled successfully.(CVE-2022-48868)

In the Linux kernel, the following vulnerability has been resolved:

smb: client: fix potential OOBs in smb2_parse_contexts()

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service (system crash). (CVE-2023-6356, CVE-2023-6535, CVE-2023-6536)

It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service. (CVE-2024-21823)

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-bounds read vulnerability. An attacker could use this to possibly cause a denial of service (system crash). (CVE-2024-23849)

It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a denial of service (system crash). (CVE-2024-24860)

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service (system crash). (CVE-2023-6356, CVE-2023-6535, CVE-2023-6536)

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-bounds read vulnerability. An attacker could use this to possibly cause a denial of service (system crash). (CVE-2024-23849)

It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a denial of service (system crash). (CVE-2024-24860)

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:
