    OPP: Fix cleanup ordering

    In the Linux kernel, the following vulnerability has been resolved: OPP: Fix cleanup ordering Commit 173e02d67494 ("OPP: Initialize scope-based pointers inline") added initialization for all pointers. In some cases, the ordering was changed so that *opp_table was initialized after *opp. This also changes the order of the registered cleanup functions. When the cleanup happens, this can cause use-after-free errors when the last reference is released and the release function _opp_kref_release tries to access the already freed opp->opp_table. Initialize *opp_table before *opp again to fix this and ensure the correct cleanup order.

    drm/amd/display: Fix DM I2C teardown race

    In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix DM I2C teardown race DM I2C adapters can remain visible to userspace while DM teardown is already in progress. A concurrent i2c-dev transfer may then enter amdgpu_dm_i2c_xfer() after the backing DM state has been torn down, leading to a NULL pointer dereference. Create a devres group around the DM I2C adapter lifetime and release it at the start of dm_hw_fini(), before HPD, IRQ, and DM state are torn down. This removes the I2C adapters first and waits for in-flight users to drain before the structures used by amdgpu_dm_i2c_xfer() disappear. This fixes

    drm/bridge: tc358767: clamp the reported AUX read size to the request

    In the Linux kernel, the following vulnerability has been resolved: drm/bridge: tc358767: clamp the reported AUX read size to the request tc_aux_transfer() clamps an AUX read to the payload limit: size_t size = min_t(size_t, DP_AUX_MAX_PAYLOAD_BYTES - 1, msg->size); After the transfer it replaces size with the byte count the controller reports in AUX_BYTES: if (size) size = FIELD_GET(AUX_BYTES, auxstatus); AUX_BYTES is GENMASK(15, 8), so it can be up to 255. Nothing clamps it back to the request. tc_aux_read_data() reads that many bytes into the 16-byte auxrdata stack buffer, then copies them into the caller buffer. A reported count

    wifi: iwlwifi: fix counter type in iwl_fwrt_dump_error_logs

    In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: fix counter type in iwl_fwrt_dump_error_logs The loop counter 'count' was declared as u8 while num_pc is u32. If firmware advertises more than 255 PC entries the counter wraps back to zero and the loop never terminates potentially causing an infinite loop or reading past the allocated pc_data array. Change the declaration to u32 to match num_pc.

    wifi: iwlwifi: mvm: fix off-by-one in TXF key sanitiser

    In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix off-by-one in TXF key sanitiser iwl_mvm_frob_txf_key_iter() tracks the last matched byte position in loop variable 'i'. When a full key match is found (match == keylen), 'i' points at the last byte of the matched key. The memset start offset should therefore be i + 1 - keylen, not i - keylen; the current code zeroes one byte before the match and leaves the final key byte un-sanitised.

    gpu: host1x: Avoid stack over-read in debug output helpers

    In the Linux kernel, the following vulnerability has been resolved: gpu: host1x: Avoid stack over-read in debug output helpers host1x_debug_output() and host1x_debug_cont() used vsnprintf(), which returns the length the formatted string would have reached with an unbounded buffer. That return value was passed straight to o->fn as the number of bytes to emit. This could cause a read past end of the output buffer if a call to host1x_debug_* produced a string longer than 256 bytes. This only affected the debugfs files as the printk debug sink ignores the number of bytes. In practice, this is very unlikely to occur. Fix by switching to vscnpr

    drm/msm: Only fini scheduler after successful init

    In the Linux kernel, the following vulnerability has been resolved: drm/msm: Only fini scheduler after successful init msm_ringbuffer_new() destroys a partially initialized ring through msm_ringbuffer_destroy() when an allocation or scheduler setup step fails. If drm_sched_init() fails before it finishes initializing the scheduler, the failure path still calls drm_sched_fini(). That teardown path assumes the scheduler work items, lists, and workqueue state were initialized. Track successful scheduler initialization and call drm_sched_fini() only after drm_sched_init() returned 0. This issue was found by a static analysis checker and conf

    scsi: ufs: core: Avoid possible memory reclaim deadlock in TX EQTR context

    In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Avoid possible memory reclaim deadlock in TX EQTR context TX EQTR may run while devfreq gear scaling has quiesced the UFS tagset. In that context, functions ufshcd_tx_eqtr(), __ufshcd_tx_eqtr() and ufs_qcom_get_rx_fom() allocate memory with GFP_KERNEL. If direct reclaim is triggered, reclaim/writeback can depend on I/O to UFS device. Because the queue is quiesced, this can cause deadlock. Use memalloc_noio_save/restore() in ufshcd_tx_eqtr() to cover all allocations in the TX EQTR call tree, including: - params->eqtr_record in ufshcd_tx_eqtr() - eqtr_da

    usb: gadget: f_uac1_legacy: remove broken string configfs attributes

    In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_uac1_legacy: remove broken string configfs attributes The UAC1_STR_ATTRIBUTE macro defines configfs show/store handlers for the fn_play, fn_cap, and fn_cntl string options. The store function contains an inverted null check on the kstrndup() return value. This means every write attempt returns -ENOMEM on success and dereferences a NULL pointer on allocation failure. The attributes have been broken and unused for many years. Remove the UAC1_STR_ATTRIBUTE macro and the three attributes it generated. The internal defaults (FILE_PCM_PLAYBACK, FILE_PCM_CAPTURE,

    uio: Fix stale info pointer in failed registration path

    In the Linux kernel, the following vulnerability has been resolved: uio: Fix stale info pointer in failed registration path After device_add(), the UIO device is visible to userspace and /dev/uioX can be opened. If a later setup step fails, __uio_register_device() unwinds the device but leaves idev->info pointing at the caller-owned struct uio_info. That is unsafe when an opener races with the failed registration path. The open file keeps a reference to the uio_device, while the caller sees registration failure and may free its struct uio_info. Later file operations can then follow idev->info and dereference freed memory. Handle post-devi

    speakup: keyhelp: guard letter_offsets possible out-of-range indexing

    In the Linux kernel, the following vulnerability has been resolved: speakup: keyhelp: guard letter_offsets possible out-of-range indexing help_init() builds letter_offsets[] by using the first byte of each function name as an index via `(start & 31) - 1`. If function_names are overridden from sysfs (root) with a name starting outside [a–z], the index underflows or exceeds the array, leading to OOB write. Function names can be overridden with the following commands as root: modprobe speakup_soft echo "0 _bad" > /sys/accessibility/speakup/i18n/function_names # then press Insert+2 on /dev/tty This fix checks the first letter in

    In the Linux kernel, the following vulnerability has been resolved: misc: bcm-vk: Use acquire/release for msgq_inited bcm_vk_sync_msgq() fills the message queue information and then sets msgq_inited. Readers call bcm_vk_drv_access_ok() before accessing the message queues and their cached queue information. atomic_set()/atomic_read() do not order those accesses. A reader can see msgq_inited set while still seeing stale queue information. Use release when publishing the initialized queues and acquire when checking the gate. Keep the clear in bcm_vk_blk_drv_access() as atomic_set(). It closes the gate and does not publish queue state to read

This leaves probe responsible for rolling back partial sysfs state and makes remove responsible for matching every file that probe created.

    ipack: ipoctal: fix UAF, null-ptr-deref, and use-after-free in cleanup on remove

    In the Linux kernel, the following vulnerability has been resolved: ipack: ipoctal: fix UAF, null-ptr-deref, and use-after-free in cleanup on remove Three issues arise when the device is removed while a tty session is still active: 1. UAF of struct ipoctal: the remove callback frees ipoctal via kfree() while tty ops may still access it. Fix by introducing kref-based lifetime management — kref is taken in install() when a tty is opened and released in cleanup() when the tty is finally destroyed; remove() uses kref_put() instead of kfree(). 2. NULL dereference in ipoctal_write_tty(): __ipoctal_remove() frees xmit_buf via tty
