    atm: clip: Fix memory leak of struct clip_vcc.

    In the Linux kernel, the following vulnerability has been resolved: atm: clip: Fix memory leak of struct clip_vcc. ioctl(ATMARP_MKIP) allocates struct clip_vcc and set it to vcc->user_back. The code assumes that vcc_destroy_socket() passes NULL skb to vcc->push() when the socket is close()d, and then clip_push() frees clip_vcc. However, ioctl(ATMARPD_CTRL) sets NULL to vcc->push() in atm_init_atmarp(), resulting in memory leak. Let's serialise two ioctl() by lock_sock() and check vcc->push() in atm_init_atmarp() to prevent memleak.

    rxrpc: Fix bug due to prealloc collision

    In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix bug due to prealloc collision When userspace is using AF_RXRPC to provide a server, it has to preallocate incoming calls and assign to them call IDs that will be used to thread related recvmsg() and sendmsg() together. The preallocated call IDs will automatically be attached to calls as they come in until the pool is empty. To the kernel, the call IDs are just arbitrary numbers, but userspace can use the call ID to hold a pointer to prepared structs. In any case, the user isn't permitted to create two calls with the same call ID (call IDs become available agai

    net: appletalk: Fix device refcount leak in atrtr_create()

    In the Linux kernel, the following vulnerability has been resolved: net: appletalk: Fix device refcount leak in atrtr_create() When updating an existing route entry in atrtr_create(), the old device reference was not being released before assigning the new device, leading to a device refcount leak. Fix this by calling dev_put() to release the old device reference before holding the new one.

    HID: quirks: Add quirk for 2 Chicony Electronics HP 5MP Cameras

    In the Linux kernel, the following vulnerability has been resolved: HID: quirks: Add quirk for 2 Chicony Electronics HP 5MP Cameras The Chicony Electronics HP 5MP Cameras (USB ID 04F2:B824 & 04F2:B82C) report a HID sensor interface that is not actually implemented. Attempting to access this non-functional sensor via iio_info causes system hangs as runtime PM tries to wake up an unresponsive sensor. Add these 2 devices to the HID ignore list since the sensor interface is non-functional by design and should not be exposed to userspace.

    tracing: Add down_write(trace_event_sem) when adding trace event

    In the Linux kernel, the following vulnerability has been resolved: tracing: Add down_write(trace_event_sem) when adding trace event When a module is loaded, it adds trace events defined by the module. It may also need to modify the modules trace printk formats to replace enum names with their values. If two modules are loaded at the same time, the adding of the event to the ftrace_events list can corrupt the walking of the list in the code that is modifying the printk format strings and crash the kernel. The addition of the event should take the trace_event_sem for write while it adds the new event. Also add a lockdep_assert_held() on t

    dmaengine: nbpfaxi: Fix memory corruption in probe()

    In the Linux kernel, the following vulnerability has been resolved: dmaengine: nbpfaxi: Fix memory corruption in probe() The nbpf->chan[] array is allocated earlier in the nbpf_probe() function and it has "num_channels" elements. These three loops iterate one element farther than they should and corrupt memory. The changes to the second loop are more involved. In this case, we're copying data from the irqbuf[] array into the nbpf->chan[] array. If the data in irqbuf[i] is the error IRQ then we skip it, so the iterators are not in sync. I added a check to ensure that we don't go beyond the end of the irqbuf[] array. I'm pretty sure thi

    In the Linux kernel, the following vulnerability has been resolved: comedi: pcl812: Fix bit shift out of bounds When checking for a supported IRQ number, the following test is used: if ((1 << it->options[1]) & board->irq_bits) { However, `it->options[i]` is an unchecked `int` value from userspace, so the shift amount could be negative or out of bounds. Fix the test by requiring `it->options[1]` to be within bounds before proceeding with the original test. Valid `it->options[1]` values that select the IRQ will be in the range [1,15]. The value 0 explicitly disables the use of interrupts.

    rxrpc: Fix recv-recv race of completed call

    In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix recv-recv race of completed call If a call receives an event (such as incoming data), the call gets placed on the socket's queue and a thread in recvmsg can be awakened to go and process it. Once the thread has picked up the call off of the queue, further events will cause it to be requeued, and once the socket lock is dropped (recvmsg uses call->user_mutex to allow the socket to be used in parallel), a second thread can come in and its recvmsg can pop the call off the socket queue again. In such a case, the first thread will be receiving stuff from the call an

    pinctrl: qcom: msm: mark certain pins as invalid for interrupts

    In the Linux kernel, the following vulnerability has been resolved: pinctrl: qcom: msm: mark certain pins as invalid for interrupts On some platforms, the UFS-reset pin has no interrupt logic in TLMM but is nevertheless registered as a GPIO in the kernel. This enables the user-space to trigger a BUG() in the pinctrl-msm driver by running, for example: `gpiomon -c 0 113` on RB2. The exact culprit is requesting pins whose intr_detection_width setting is not 1 or 2 for interrupts. This hits a BUG() in msm_gpio_irq_set_type(). Potentially crashing the kernel due to an invalid request from user-space is not optimal, so let's go through the pins

    rxrpc: Fix oops due to non-existence of prealloc backlog struct

    In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix oops due to non-existence of prealloc backlog struct If an AF_RXRPC service socket is opened and bound, but calls are preallocated, then rxrpc_alloc_incoming_call() will oops because the rxrpc_backlog struct doesn't get allocated until the first preallocation is made. Fix this by returning NULL from rxrpc_alloc_incoming_call() if there is no backlog struct. This will cause the incoming call to be aborted.

    clone_private_mnt(): make sure that caller has CAP_SYS_ADMIN in the right userns

    In the Linux kernel, the following vulnerability has been resolved: clone_private_mnt(): make sure that caller has CAP_SYS_ADMIN in the right userns What we want is to verify there is that clone won't expose something hidden by a mount we wouldn't be able to undo. "Wouldn't be able to undo" may be a result of MNT_LOCKED on a child, but it may also come from lacking admin rights in the userns of the namespace mount belongs to. clone_private_mnt() checks the former, but not the latter. There's a number of rather confusing CAP_SYS_ADMIN checks in various userns during the mount, especially with the new mount API; they serve different purpos

    In the Linux kernel, the following vulnerability has been resolved: usb: gadget: configfs: Fix OOB read on empty string write When writing an empty string to either 'qw_sign' or 'landingPage' sysfs attributes, the store functions attempt to access page[l - 1] before validating that the length 'l' is greater than zero. This patch fixes the vulnerability by adding a check at the beginning of os_desc_qw_sign_store() and webusb_landingPage_store() to handle the zero-length input case gracefully by returning immediately.
