CVE-2023-53515

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

NFSD: Protect against send buffer overflow in NFSv2 READ

Since before the git era, NFSD has conserved the number of pages held by each nfsd thread by combining the RPC receive and send buffers into a single array of pages. This works because there are no cases where an operation needs a large RPC Call message and a large RPC Reply at the same time.

Once an RPC Call has been received, svc_process() updates svc_rqst::rq_res to describe the part of rq_pages that can be used for constructing the Reply. This means that the send buffer (rq_res) shrinks when the received RPC record containing the RPC Call is large.

A client can force this shrinkage on TCP by sending a correctly- formed RPC Call header contained in an RPC record that is excessively large. The full maximum payload size cannot be constructed in that case.(CVE-2022-50410)

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

media: az6007: Fix null-ptr-deref in az6007_i2c_xfer()

In az6007_i2c_xfer, msg is controlled by user. When msg[i].buf is null and msg[i].len is zero, former checks on msg[i].buf would be passed. Malicious data finally reach az6007_i2c_xfer. If accessing msg[i].buf[0] without sanity check, null ptr deref would happen. We add check on msg[i].len to prevent crash.

Similar commit: commit 0ed554fd769a ("media: dvb-usb: az6027: fix null-ptr-deref in az6027_i2c_xfer()")(CVE-2023-53220)

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

kobject: Add sanity check for kset->kobj.ktype in kset_register()

When I register a kset in the following way: static struct kset my_kset; kobject_set_name(&my_kset.kobj, "my_kset"); ret = kset_register(&my_kset);

A null pointer dereference exception is occurred: [ 4453.568337] Unable to handle kernel NULL pointer dereference at
virtual address 0000000000000028 ... ... [ 4453.810361] Call trace: [ 4453.813062] kobject_get_ownership+0xc/0x34 [ 4453.817493] kobject_add_internal+0x98/0x274 [ 4453.822005] kset_register+0x5c/0xb4 [ 4453.825820] my_kobj_init+0x44/0x1000 [my_kset] ... ...

Because I didn't initialize my_kset.kobj.ktype.

According to the description in Documentation/core-api/kobject.rst:

• A ktype is the type of object that embeds a kobject. Every structure that embeds a kobject needs a corresponding ktype.

So add sanity check to make sure kset->kobj.ktype is not NULL.(CVE-2023-53480)

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

virtio-mmio: don't break lifecycle of vm_dev

vm_dev has a separate lifecycle because it has a 'struct device' embedded. Thus, having a release callback for it is correct.

Allocating the vm_dev struct with devres totally breaks this protection, though. Instead of waiting for the vm_dev release callback, the memory is freed when the platform_device is removed. Resulting in a use-after-free when finally the callback is to be called.

To easily see the problem, compile the kernel with CONFIG_DEBUG_KOBJECT_RELEASE and unbind with sysfs.

The fix is easy, don't use devres in this case.

net/tunnel: wait until all sk_user_data reader finish before releasing the sock

There is a race condition in vxlan that when deleting a vxlan device during receiving packets, there is a possibility that the sock is released after getting vxlan_sock vs from sk_user_data. Then in later vxlan_ecn_decapsulate(), vxlan_get_sk_family() we will got NULL pointer dereference. e.g.

Fix this by waiting for all sk_user_data reader to finish before releasing the sock.(CVE-2022-50405)

In the Linux kernel, there is a vulnerability in the USB host controller interface (xHCI). When the xHC host is dying or being removed, endpoints are not properly cleaned up, remaining in the bandwidth list when freeing the virtual device. This causes a list_del corruption kernel crash when unbinding xhci-pci, as xhci_mem_cleanup() later attempts to delete already freed endpoints from the bandwidth list. This vulnerability only affects hosts that use software bandwidth checking, which currently is only the xHC in Intel Panther Point PCH (Ivy Bridge).(CVE-2022-50470)

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

virtio-mmio: don't break lifecycle of vm_dev

vm_dev has a separate lifecycle because it has a 'struct device' embedded. Thus, having a release callback for it is correct.

Allocating the vm_dev struct with devres totally breaks this protection, though. Instead of waiting for the vm_dev release callback, the memory is freed when the platform_device is removed. Resulting in a use-after-free when finally the callback is to be called.

To easily see the problem, compile the kernel with CONFIG_DEBUG_KOBJECT_RELEASE and unbind with sysfs.

The fix is easy, don't use devres in this case.

Found during my research about object lifetime problems.
