    wifi: ath10k: Delay the unmapping of the buffer

    In the Linux kernel, the following vulnerability has been resolved: wifi: ath10k: Delay the unmapping of the buffer On WCN3990, we are seeing a rare scenario where copy engine hardware is sending a copy complete interrupt to the host driver while still processing the buffer that the driver has sent, this is leading into an SMMU fault triggering kernel panic. This is happening on copy engine channel 3 (CE3) where the driver normally enqueues WMI commands to the firmware. Upon receiving a copy complete interrupt, host driver will immediately unmap and frees the buffer presuming that hardware has processed the buffer. In the issue case, upon r

    smack: fix bug: unprivileged task can create labels

    In the Linux kernel, the following vulnerability has been resolved: smack: fix bug: unprivileged task can create labels If an unprivileged task is allowed to relabel itself (/smack/relabel-self is not empty), it can freely create new labels by writing their names into own /proc/PID/attr/smack/current This occurs because do_setattr() imports the provided label in advance, before checking "relabel-self" list. This change ensures that the "relabel-self" list is checked before importing the label.

    crypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id

    In the Linux kernel, the following vulnerability has been resolved: crypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id Use check_add_overflow() to guard against potential integer overflows when adding the binary blob lengths and the size of an asymmetric_key_id structure and return ERR_PTR(-EOVERFLOW) accordingly. This prevents a possible buffer overflow when copying data from potentially malicious X.509 certificate fields that can be arbitrarily large, such as ASN.1 INTEGER serial numbers, issuer names, etc.

    RDMA/rxe: Fix null deref on srq->rq.queue after resize failure

    In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix null deref on srq->rq.queue after resize failure A NULL pointer dereference can occur in rxe_srq_chk_attr() when ibv_modify_srq() is invoked twice in succession under certain error conditions. The first call may fail in rxe_queue_resize(), which leads rxe_srq_from_attr() to set srq->rq.queue = NULL. The second call then triggers a crash (null deref) when accessing srq->rq.queue->buf->index_mask.

    In the Linux kernel, the following vulnerability has been resolved: wifi: rtl818x: rtl8187: Fix potential buffer underflow in rtl8187_rx_cb() The rtl8187_rx_cb() calculates the rx descriptor header address by subtracting its size from the skb tail pointer. However, it does not validate if the received packet (skb->len from urb->actual_length) is large enough to contain this header. If a truncated packet is received, this will lead to a buffer underflow, reading memory before the start of the skb data area, and causing a kernel panic.

    ALSA: dice: fix buffer overflow in detect_stream_formats()

    In the Linux kernel, the following vulnerability has been resolved: ALSA: dice: fix buffer overflow in detect_stream_formats() The function detect_stream_formats() reads the stream_count value directly from a FireWire device without validating it. This can lead to out-of-bounds writes when a malicious device provides a stream_count value greater than MAX_STREAMS. Fix by applying the same validation to both TX and RX stream counts in detect_stream_formats().

    In the Linux kernel, the following vulnerability has been resolved: can: gs_usb: gs_usb_receive_bulk_callback(): check actual_length before accessing header The driver expects to receive a struct gs_host_frame in gs_usb_receive_bulk_callback(). Use struct_group to describe the header of the struct gs_host_frame and check that we have at least received the header before accessing any members of it. To resubmit the URB, do not dereference the pointer chain "dev->parent->hf_size_rx" but use "parent->hf_size_rx" instead. Since "urb->context" contains "parent", it is always defined, while "dev" is not defined if the URB it too short.
