    firmware: arm_scmi: Fix transport device teardown lookup

    In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Fix transport device teardown lookup SCMI transport devices are deliberately excluded from normal SCMI bus matching so protocol drivers cannot bind to the internal transport children. However, scmi_device_destroy() uses the same protocol/name lookup to find devices that must be unregistered during channel teardown. Split the match helper so driver matching still skips transport devices, while explicit child lookup can find them for teardown. Use a shared transport-device name prefix macro for both matching and name generation. Since transport-device na

    cxl/features: Reject Get Feature count larger than the output buffer

    In the Linux kernel, the following vulnerability has been resolved: cxl/features: Reject Get Feature count larger than the output buffer cxlctl_get_feature() sizes its output buffer from the user's fwctl_rpc.out_len, but the device is told to write cxl_mbox_get_feat_in.count bytes into rpc_out->payload, which is a separate user-controlled value. Nothing bounds count against out_len, so a small out_len with a large count overflows the kvzalloc()'d buffer. A heap OOB write reachable from FWCTL_RPC. Reject requests where count exceeds the available payload room, before allocating.

    cxl/features: Reject Set Features output buffer smaller than the header

    In the Linux kernel, the following vulnerability has been resolved: cxl/features: Reject Set Features output buffer smaller than the header cxlctl_set_feature() sizes its output buffer from the user's fwctl_rpc.out_len but never checks it is large enough to hold even the fwctl_rpc_cxl_out header. With out_len == 0 , kvzalloc() returns ZERO_SIZE_PTR, which passes the !rpc_out check, the subsequent rpc_out->size = 0 then writes through the poison pointer. Reject requests whose output buffer can't hold the response header, before allocating. The Set Feature reply carries no payload, so the header is all that is required.

    cxl/features: Clamp Get Feature output size to the remaining buffer

    In the Linux kernel, the following vulnerability has been resolved: cxl/features: Clamp Get Feature output size to the remaining buffer cxl_get_feature() reads a feature in a loop but passes a fixed size_out as the output capacity every iteration. On the last partial iteration the buffer has less room left, so a device that returns more than asked can overflow feat_out. Use the per-iter size data_to_rd_size, which already tracks the remaining room, as the output capacity.

    dax: read holder_ops once in dax_holder_notify_failure()

    In the Linux kernel, the following vulnerability has been resolved: dax: read holder_ops once in dax_holder_notify_failure() dax_holder_notify_failure() reads dax_dev->holder_ops twice without READ_ONCE() -- once for the NULL check and once for the indirect notify_failure() call. A concurrent fs_put_dax() can clear holder_ops between the two reads, so the check can observe a non-NULL pointer while the call dereferences NULL. (kill_dax() also clears holder_ops, but only after synchronize_srcu(), so it cannot race a reader that is inside dax_read_lock(); fs_put_dax() does no such synchronization.) Fetch holder_ops once into a local with READ

    irqchip/renesas-irqc: Fix generic interrupt chip leak on remove

    In the Linux kernel, the following vulnerability has been resolved: irqchip/renesas-irqc: Fix generic interrupt chip leak on remove The driver allocates domain generic chips probe. However, on driver removal, the generic chips are not automatically freed when the interrupt domain is removed because the domain flags do not include IRQ_DOMAIN_FLAG_DESTROY_GC. This causes both the domain generic chips structure and the associated generic chips to be leaked. Additionally, the generic chips remain on the global list and may later be accessed by generic interrupt chip suspend, resume, or shutdown callbacks after the driver has been removed, pote

    media: ipu6: Do not free aux device pdata after init

    In the Linux kernel, the following vulnerability has been resolved: media: ipu6: Do not free aux device pdata after init ipu6_bus_initialize_device() stores the isys/psys pdata pointer in struct ipu6_bus_device and initializes the auxiliary device. After that point, error unwinding must drop the auxiliary device reference and let ipu6_bus_release() free both the bus device and adev->pdata. The isys and psys init paths already call put_device() when MMU initialization fails, and ipu6_bus_add_device() calls auxiliary_device_uninit() on auxiliary_device_add() failure. Both paths therefore run the bus release callback. The extra kfree(pdata) i

    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

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

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.

    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.

    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
