    LoongArch: Do not save/restore percpu base register in rethook trampoline

    In the Linux kernel, the following vulnerability has been resolved: LoongArch: Do not save/restore percpu base register in rethook trampoline The rethook trampoline saves $r21 ($u0), the percpu base, into its frame at entry and restores it at exit. Inbetween rethook_trampoline_handler() may schedule via preempt_enable_notrace(). If the task migrates to another CPU, the frame's $r21 holds the old CPU's percpu base, and restoring it poisons $r21 on the new CPU. Until the next user->kernel transition heals $r21, all this_cpu_*() accesses (runqueues, RCU per-CPU data, timer tick programming, FPU ownership) hit the wrong CPU's percpu area. Und

    LoongArch: Avoid preempt count underflow without probe

    In the Linux kernel, the following vulnerability has been resolved: LoongArch: Avoid preempt count underflow without probe LoongArch uses break 11 for the breakpoint placed after an instruction that Kprobes executes out of line. Since userspace can issue the same break instruction, do_bp() can reach kprobe_singlestep_handler() when there is no current probe. The handler actually returns false in this case, but it first calls preempt_enable_no_resched(). The corresponding preempt_disable() is done by kprobe_breakpoint_handler() on a real Kprobe hit, so it has not run here. As a result, an ordinary userspace breakpoint (code 11) underflows t

    In the Linux kernel, the following vulnerability has been resolved: media: airspy: use vb2_video_unregister_device() on disconnect to fix NULL deref airspy_disconnect() clears s->udev under v4l2_lock, but airspy_stop_streaming() unconditionally calls airspy_ctrl_msg() and airspy_free_stream_bufs() afterwards.

    media: cec: core: Fix kmemleak due to missed rc_free_device() call

    In the Linux kernel, the following vulnerability has been resolved: media: cec: core: Fix kmemleak due to missed rc_free_device() call The commit dccc0c3ddf8f ("media: rc: fix race between unregister and urb/irq callbacks") removed the implicit call to rc_free_device() from rc_unregister_device(). However, the commit missed to remove the NULL assignment of adap->rc that is now causing rc_free_device() to never be called on an allocated rc device. kmemleak reports following after e.g. dw-hdmi unbind: unreferenced object 0xffff00010ac10000 (size 4096): comm "kworker/u16:1", pid 39, jiffies 4294897739 hex dump (first 32 bytes): 20 23

    In the Linux kernel, the following vulnerability has been resolved: media: cec: disable delayed work before freeing an interrupted transmit cec_transmit_msg_fh() drops adap->lock to wait for a blocking transmit in wait_for_completion_killable(). If that wait is interrupted by a signal, cancel_delayed_work_sync() can run before the CEC kthread arms the reply timeout via schedule_delayed_work(&data->work) in cec_transmit_done_ts().

    media: cedrus: fix memory leak in cedrus_init_ctrls()

    In the Linux kernel, the following vulnerability has been resolved: media: cedrus: fix memory leak in cedrus_init_ctrls() In cedrus_init_ctrls(), the V4L2 control handler is initialized before allocating memory for ctx->ctrls. If this allocation fails, the function returns -ENOMEM without freeing the previously allocated handler resources, leading to a memory leak. Fix this by calling v4l2_ctrl_handler_free() on the ctx->ctrls allocation failure path. The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing v6.13-rc1. The tool is still under development and is not yet p

    media: cobalt: Avoid freeing ALSA private data twice

    In the Linux kernel, the following vulnerability has been resolved: media: cobalt: Avoid freeing ALSA private data twice snd_cobalt_card_create() stores cobsc in sc->private_data and installs snd_cobalt_card_private_free() as sc->private_free. From that point, snd_card_free(sc) releases cobsc through the ALSA card cleanup path. If cobalt_alsa_init() fails after snd_cobalt_card_create(), the err_exit_free path calls snd_card_free(sc) and then kfree(cobsc). That second free releases the same object again. Remove the explicit kfree(cobsc) and leave ownership with the ALSA card. This issue was found by a static analysis checker and confirmed

    media: cx23885: cancel NetUP CI work before teardown

    In the Linux kernel, the following vulnerability has been resolved: media: cx23885: cancel NetUP CI work before teardown netup_ci_exit() frees a netup_ci_state while its work item, netup_read_ci_status(), may still be pending or running on the system workqueue. The worker obtains the state with container_of() and dereferences it, so it must not outlive the state. netup_ci_init() queues the initial status read, and CI GPIO interrupts subsequently queue the same work from netup_ci_slot_status(). During remove, cx23885_finidev() calls free_irq() before the CI device is unregistered. free_irq() prevents further IRQ handlers from running, but d

    In the Linux kernel, the following vulnerability has been resolved: media: em28xx: defer audio-only extension registration The audio-only path registers extensions while probing the primary device. For a dual-TS board, this happens before dev_next is created. The duplicate device inherits is_audio_only and is then independently inserted into em28xx_devlist. The list is intended to contain only primary devices: extension operations reach the secondary device through dev_next. The independently linked secondary can be freed during disconnect while its list node remains reachable, resulting in a use-after-free. Defer audio-only extension reg

    In the Linux kernel, the following vulnerability has been resolved: media: em28xx: fix use-after-free of dev_next->devlist on disconnect When a device with has_dual_ts=1 is probed and the is_audio_only path is taken, both dev and dev->dev_next are added to the global em28xx_devlist via em28xx_init_extension(). However, during disconnect, em28xx_close_extension(dev) only calls list_del(&dev->devlist), leaving dev->dev_next->devlist still linked in the global list. When dev_next is subsequently freed via kref_put(), its devlist entry becomes a dangling pointer in em28xx_devlist. The next device probe that calls em28xx_init_extension() trigger

    media: go7007: defer the ALSA v4l2 put until card release

    In the Linux kernel, the following vulnerability has been resolved: media: go7007: defer the ALSA v4l2 put until card release go7007_snd_init() already takes a v4l2_device reference for the ALSA side, but go7007_snd_remove() drops it immediately after calling snd_card_free_when_closed(). That is too early when a userspace process still has the capture PCM open. The ALSA card and its PCM callbacks remain alive until the last file is closed, so the release path can still reach struct go7007 through pcm->private_data and call go7007_snd_hw_free() after the V4L2 release path has freed the object.

    In the Linux kernel, the following vulnerability has been resolved: media: i2c: ov02a10: fix endpoint parsing use-after-free The ov02a10_check_hwcfg() function calls fwnode_handle_put(ep) immediately after allocating and parsing the endpoint. However, it subsequently calls fwnode_property_read_u32() using the same 'ep' handle, leading to a potential use-after-free. Additionally, reading the optional 'ovti,mipi-clock-voltage' property used to overwrite the 'ret' variable. If the property was missing, 'ret' would become negative, and this failure code would be incorrectly returned at the end of the function, causing probe to fail entirely.

    In the Linux kernel, the following vulnerability has been resolved: media: i2c: ov7740: fix use-after-destroy in remove The ov7740_remove() function had a severe teardown order bug where it destroyed the driver's mutex before freeing the V4L2 control handler which relies on that mutex, leading to a use-after-destroy kernel panic. Furthermore, the driver explicitly called v4l2_ctrl_handler_free() and mutex_destroy() sequentially, but then called ov7740_free_controls() which invokes both of them a second time, resulting in a double-free. This patch fixes the issue by unregistering the subdevice first, and relying exclusively on ov7740_free_c
