    KVM: x86: Ignore pending PV EOI if the vCPU has since disabled PV EOIs

    In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Ignore pending PV EOI if the vCPU has since disabled PV EOIs Ignore KVM's internal "service pending PV EOI" request if the vCPU has disabled PV EOIs since the request was made. Asserting that PV EOIs are enabled can fail if reading guest memory in pv_eoi_get_user() fails, i.e. if pv_eoi_test_and_clr_pending() bails early, *and* the vCPU also disables PV EOIs. kernel BUG at arch/x86/kvm/lapic.c:3338! Oops: invalid opcode: 0000 [#1] SMP CPU: 4 UID: 1000 PID: 890 Comm: pv_eoi_test Not tainted 7.0.0-d585aa5894d8-vm #337 PREEMPT Hardware name: QEMU Standard P

    KVM: Move kvm_io_bus_get_dev() locking responsibilities to callers

    In the Linux kernel, the following vulnerability has been resolved: KVM: Move kvm_io_bus_get_dev() locking responsibilities to callers kvm_io_bus_get_dev() returns a device that is only matched by the address, and nothing else. This can cause a lifetime issue if the matched device is not the expected type, as by the time the caller can introspect the object, it might be gone (the srcu lock having been dropped). Given that there is only a single user of this helper, the simplest option is to move the locking responsibility to the caller, which can keep the srcu lock held for as long as it wants. Note that this aligns with other kvm_io_bus*

    ASoC: SOF: ipc3-control: Fix heap overflow in bytes_ext put/get

    In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc3-control: Fix heap overflow in bytes_ext put/get The ipc_control_data buffer is allocated as kzalloc(max_size), where max_size covers the entire struct sof_ipc_ctrl_data including its flexible array payload. However, the bounds checks in bytes_ext_put and _bytes_ext_get compared user data lengths against max_size directly, ignoring that cdata->data sits at an offset of sizeof(struct sof_ipc_ctrl_data) bytes into the allocation. This allowed writing up to sizeof(struct sof_ipc_ctrl_data) bytes past the end of the heap buffer from unprivileged userspace via th

    ASoC: SOF: ipc3-control: Validate size in snd_sof_update_control

    In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc3-control: Validate size in snd_sof_update_control In snd_sof_update_control(), firmware-provided cdata->num_elems is checked against local_cdata->data->size but never against the actual allocation size. If local_cdata->data->size was previously set to an inconsistent value, the memcpy could write past the allocated buffer. Add a bounds check to ensure num_elems fits within the available space in the ipc_control_data allocation before copying.

    ASoC: mediatek: mt8192: Check runtime resume during probe

    In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8192: Check runtime resume during probe The MT8192 AFE probe enables runtime PM temporarily while reinitializing the regmap cache from hardware, but it uses pm_runtime_get_sync() without checking the return value. If runtime resume fails, probe keeps going without the device necessarily being accessible, and pm_runtime_get_sync() may leave the PM usage count incremented. The regmap_reinit_cache() failure path also returns before dropping the temporary PM reference and before clearing pm_runtime_bypass_reg_ctl. Use pm_runtime_resume_and_get() so resume fa

    ASoC: mediatek: mt8192: Release reserved memory on cleanup

    In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8192: Release reserved memory on cleanup The MT8192 AFE probe calls of_reserved_mem_device_init() and falls back to preallocated buffers when no reserved memory region is available. When the reserved memory assignment succeeds, however, the driver never releases it. Register a devm cleanup action after a successful reserved-memory assignment so the assignment is released on probe failure and driver unbind.

    In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8183: Release reserved memory on cleanup The MT8183 AFE probe can assign reserved memory with of_reserved_mem_device_init(), but the assignment is never released on driver removal or later probe failures. Register a devm cleanup action so the reserved memory assignment is released consistently, matching newer Mediatek AFE drivers.
