    wifi: iwlwifi: mvm: fix P2P-Device binding handling

    In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix P2P-Device binding handling Our binding handling for P2P-Device can run into the following scenario, as observed by our testing: - a station interface is connected on some channel - the P2P-Device does a remain-on-channel (ROC) on that channel - the ROC ends, and the P2P-Device is removed from the binding, but the phy_ctxt pointer is left around as a PHY cache so we don't need to recalibrate to the channel again and again in case it's not shared - a binding update by the station interface, even a removal, will re-add the P2P-Device t

    drm/amd/display: Avoid DPMS-on for phantom stream

    In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Avoid DPMS-on for phantom stream [Why & How] Calling dc_update_planes_and_stream separately for stream and its phantom stream causes a NULL pointer dereference, since the phantom is destroyed on the first call. Skip the call for phantom streams.

HCD_FLAG_HW_ACCESSIBLE is set and cleared in suspend and resume. Also print a warning if xhci is being suspended with commands still pending on the command ring.

    drm/amdgpu: harden FRU PIA parsing with bounded helpers

    In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: harden FRU PIA parsing with bounded helpers Replace the open-coded TLV walk with fru_pia_advance() and fru_pia_copy_field() helpers that bound every read by the actual EEPROM data length, preventing out-of-bounds reads on truncated or malformed FRU data.

    drm/amdgpu/ras: add ras_suspend callback and use it for cp_ecc_error_irq

    In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/ras: add ras_suspend callback and use it for cp_ecc_error_irq cp_ecc_error_irq is acquired in amdgpu_gfx_ras_late_init() but released in gfx_v9_0_hw_fini(), so the put site has to query amdgpu_irq_enabled() because the get is skipped on SR-IOV VF. ras_late_init / ras_fini have no suspend counterpart, so move the put to amdgpu_gfx_ras_suspend() / amdgpu_gfx_ras_fini() and add a matching ras_suspend callback that is invoked from amdgpu_ras_suspend() before disable_all_features().

    cxl/region: Validate partition index before array access

    In the Linux kernel, the following vulnerability has been resolved: cxl/region: Validate partition index before array access construct_region() reads cxled->part and uses it to index cxlds->part[] without checking for a negative value. If the partition was never resolved, part remains at its initial value of -1, causing an out-of-bounds array access. Add a guard to return -EBUSY when part is negative. The check was dropped during a merge.

    drm/amdkfd: fix SMI event cross-process information leak

    In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix SMI event cross-process information leak kfd_smi_ev_enabled() skips the suser privilege check when pid=0. PROCESS_START, PROCESS_END, and VMFAULT events are emitted with pid=0 while carrying another process's PID and command name, so any /dev/kfd user in the render group can monitor all GPU workloads. Pass the target process PID into kfd_smi_event_add() for these events so the existing per-client filter restricts delivery to the owning process or CAP_SYS_ADMIN subscribers.

    bpf: NUL-terminate replaced sysctl value

    In the Linux kernel, the following vulnerability has been resolved: bpf: NUL-terminate replaced sysctl value When writing to sysctls, proc_sys_call_handler() guarantees that the buffer passed to proc handlers is NUL-terminated. If bpf_sysctl_set_new_value() replaces the pending sysctl value, it can hand a replacement buffer directly to proc handlers. However, the helper currently copies only buf_len bytes into that buffer without appending a NUL terminator, leaving downstream parsers vulnerable to out-of-bounds access. Fix this by appending a '\0' after the replaced value to restore the expected sysctl semantics. Since the helper already r

    hsr: broadcast netlink notifications in the device's net namespace

    In the Linux kernel, the following vulnerability has been resolved: hsr: broadcast netlink notifications in the device's net namespace The HSR generic netlink family sets .netnsok = true. HSR devices can live in network namespaces other than init_net. Two async notifiers broadcast events with genlmsg_multicast(). They are hsr_nl_ringerror() and hsr_nl_nodedown(). That helper delivers only on the default genl socket in init_net. So the events always land in init_net. The network namespace of the device does not matter. This has two effects. A listener in the device's own namespace never sees its own ring error and node down events. A privi

    ALSA: es18xx: check control allocation before private data setup

    In the Linux kernel, the following vulnerability has been resolved: ALSA: es18xx: check control allocation before private data setup snd_es18xx_mixer() creates controls with snd_ctl_new1() and then stores bookkeeping pointers or sets private_free before calling snd_ctl_add(). snd_ctl_new1() can return NULL on allocation failure, so those writes can dereference a NULL control pointer. Check the returned control pointers before using them and return -ENOMEM on allocation failure.

    netfilter: nf_conntrack: use get_unaligned_be32() in tcp_sack()

    In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_conntrack: use get_unaligned_be32() in tcp_sack() The timestamp-only fast path dereferences the option stream as *(__be32 *)ptr, which assumes 4-byte alignment that the TCP option stream does not guarantee. Use get_unaligned_be32() instead, which reads the value safely and already returns host byte order, so the htonl() on the comparison constant can be dropped. This matches the existing get_unaligned_be32() use later in the same function.

    btrfs: tree-checker: validate names in ROOT_REF and ROOT_BACKREF

    In the Linux kernel, the following vulnerability has been resolved: btrfs: tree-checker: validate names in ROOT_REF and ROOT_BACKREF ROOT_REF and ROOT_BACKREF items contain a struct btrfs_root_ref followed by the subvolume name. Several readers assume that this layout is already valid and then use the on-disk name length directly. A corrupted item can therefore make those readers address bytes outside the item, and BTRFS_IOC_GET_SUBVOL_INFO can copy too many bytes into its fixed-size UAPI name buffer. Validate ROOT_REF and ROOT_BACKREF items in tree-checker before any reader uses them. Reject records that do not contain a non-empty name, w

A malicious RDMA client can send usr_len > off causing an integer underflow, resulting in data_len wrapping to a huge size_t value which is then passed to the rdma_ev callback as a memory length, leading to out-of-bounds memory access. Fix by reading and validating usr_len <= off before rtrs_srv_get_ops_ids() in both process_read() and process_write(),
