    mmc: davinci: avoid NULL deref of host->data in IRQ handler

    In the Linux kernel, the following vulnerability has been resolved: mmc: davinci: avoid NULL deref of host->data in IRQ handler mmc_davinci_irq() returns early only when both host->cmd and host->data are NULL: if (host->cmd == NULL && host->data == NULL) { ... return IRQ_NONE; } So we may legitimately reach the rest of the handler with host->data == NULL (and therefore data == NULL). The DATDNE branch already guards against this with an explicit "if (data != NULL)" check, but the subsequent TOUTRD ("read data timeout") and CRCWR/CRCRD ("data CRC error") branches dereference data unconditionally: if (qstatus & MM

    pinctrl: mediatek: paris: bypass pinctrl GPIO layer in set GPIO direction

    In the Linux kernel, the following vulnerability has been resolved: pinctrl: mediatek: paris: bypass pinctrl GPIO layer in set GPIO direction pinctrl_gpio_direction_input() / pinctrl_gpio_direction_output() take the pinctrl mutex. This causes a gpiochip operations to need to sleep. Worse yet, the .can_sleep field in the gpiochip is not set. This causes the shared GPIO proxy to trip over, as it uses gpiod_cansleep() to check whether it can use a spinlock or needs a mutex. In this case, it ends up taking a spinlock, then calls pinctrl_gpio_direction_output(), which takes a mutex. This causes a huge warning. While this class of Mediatek hardw

    coresight: perf: Retrieve path and source from event data

    In the Linux kernel, the following vulnerability has been resolved: coresight: perf: Retrieve path and source from event data ETM perf callbacks currently use the per-CPU csdev_src pointer, which can race with updates during device registration and unregistration. The AUX setup already builds and stores the path in the event data. Use this path to retrieve the source instead of csdev_src to avoid the race. Export coresight_get_source() and add etm_event_get_ctxt_path() to retrieve the context's path and its source with READ_ONCE() / WRITE_ONCE() accessors. Give the comments to explain why this approach is safe when pause or resume callbac

    drm/amdgpu/userq: pin mqd and fw object bo to avoid eviction

    In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: pin mqd and fw object bo to avoid eviction mqd and fw objects are queue core objects which should remain valid and never be unmapped and evicted for user queues to work properly. During eviction if these buffers are evicted the hw continue to use the invalid addresses and caused page faults and system hung.

    drm/amdkfd: Fix OOB memory exposure in get_wave_state()

    In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix OOB memory exposure in get_wave_state() The get_wave_state() function for v9 trusts cp_hqd_cntl_stack_size and cp_hqd_cntl_stack_offset values read directly from the MQD, which are written by GPU microcode and fully attacker-controlled on the CRIU-restore path (via AMDKFD_IOC_RESTORE_PROCESS with H3). this leads to an unbounded copy_to_user() that can leak adjacent GTT/kernel memory. If offset > size, integer underflow produces a ~4 GiB read length, if size is set to 1 MiB against a 4 KiB allocation, we leak 1 MiB of adjacent kernel memory (other queues' MQ

    wifi: mac80211: don't call ieee80211_handle_reconfig_failure when not needed

    In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't call ieee80211_handle_reconfig_failure when not needed In case reconfiguration of NAN fails, we call ieee80211_handle_reconfig_failure, that marks all interfaces as not in the driver. Then, at the error path of the reconfig, cfg80211_shutdown_all_interfaces is called to destroy all the interfaces. If we have any other interface but the NAN one, for example a BSS station, then when its state (links, stations) will be removed, we won't tell the driver about this, because we will think that the interfaces are not in the driver, and then drivers might rem

    net/rds: Don't sleep inside rds_ib_conn_path_shutdown

    In the Linux kernel, the following vulnerability has been resolved: net/rds: Don't sleep inside rds_ib_conn_path_shutdown New rds rdma self tests exposed a hang when tearing down the ib network configs. This is caused by the shutdown worker thread sleeping on the wait_event call, which blocks other work items in the queue. Fix this by changing wait_event to wait_event timeout, and looping until the wait check succeeds.

Passing NULL to hcd_to_vhci_hcd() does not return NULL - it returns a pointer offset of 0x260, causing a NULL pointer dereference when that value is subsequently dereferenced. Add a NULL check on hcd before calling hcd_to_vhci_hcd(). Move status_show_not_ready() above status_show_vhci() to make it calla

Handling errors in UAS and the storage driver may involve resetting a device. The thread doing the reset itself relies on VM magic. However, that is insufficient, as resetting a device involves resuming it. Resumption as well as resetting involves conrol transfers to the parent of the device to be reset. That may be a root hub. Hence usbcore must heed the flags passed to usb_submit_urb() processing control transfers to root hubs. The pro
