In the Linux kernel, the following vulnerability has been resolved: drm/panel-simple: fix connector type for DataImage SCF0700C48GGU18 panel The connector type for the DataImage SCF0700C48GGU18 panel is missing and devm_drm_panel_bridge_add() requires connector type to be set. This leads to a warning and a backtrace in the kernel log and panel does not work: " WARNING: CPU: 3 PID: 38 at drivers/
UpdatedIn the Linux kernel, the following vulnerability has been resolved: udp: call skb_orphan() before skb_attempt_defer_free() Standard UDP receive path does not use skb->destructor. But skmsg layer does use it, since it calls skb_set_owner_sk_safe() from udp_read_skb(). This then triggers this warning in skb_attempt_defer_free(): DEBUG_NET_WARN_ON_ONCE(skb->destructor); We must call skb_orp
UpdatedIn the Linux kernel, the following vulnerability has been resolved: libceph: make calc_target() set t->paused, not just clear it Currently calc_target() clears t->paused if the request shouldn't be paused anymore, but doesn't ever set t->paused even though it's able to determine when the request should be paused. Setting t->paused is left to __submit_request() which is fine for regular requests
UpdatedIn the Linux kernel, the following vulnerability has been resolved: virtio_net: fix device mismatch in devm_kzalloc/devm_kfree Initial rss_hdr allocation uses virtio_device->device, but virtnet_set_queues() frees using net_device->device.

UpdatedIn the Linux kernel, the following vulnerability has been resolved: PM: hibernate: Fix crash when freeing invalid crypto compressor When crypto_alloc_acomp() fails, it returns an ERR_PTR value, not NULL. The cleanup code in save_compressed_image() and load_compressed_image() unconditionally calls crypto_free_acomp() without checking for ERR_PTR, which causes crypto_acomp_tfm() to dereference an
UpdatedIn the Linux kernel, the following vulnerability has been resolved: btrfs: fix NULL pointer dereference in do_abort_log_replay() Coverity reported a NULL pointer dereference issue (CID 1666756) in do_abort_log_replay(). When btrfs_alloc_path() fails in replay_one_buffer(), wc->subvol_path is NULL, but btrfs_abort_log_replay() calls do_abort_log_replay() which unconditionally dereferences wc->sub
UpdatedIn the Linux kernel, the following vulnerability has been resolved: idpf: fix aux device unplugging when rdma is not supported by vport If vport flags do not contain VIRTCHNL2_VPORT_ENABLE_RDMA, driver does not allocate vdev_info for this vport. This leads to kernel NULL pointer dereference in idpf_idc_vport_dev_down(), which references vdev_info for every vport regardless. Check, if vdev_info
UpdatedIn the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix NULL pointer crash in bnxt_ptp_enable during error cleanup When bnxt_init_one() fails during initialization (e.g., bnxt_init_int_mode returns -ENODEV), the error path calls bnxt_free_hwrm_resources() which destroys the DMA pool and sets bp->hwrm_dma_pool to NULL. Subsequently, bnxt_ptp_clear() is called, which invok
UpdatedIn the Linux kernel, the following vulnerability has been resolved: wifi: mac80211_hwsim: fix typo in frequency notification The NAN notification is for 5745 MHz which corresponds to channel 149 and not 5475 which is not actually a valid channel.

UpdatedIn the Linux kernel, the following vulnerability has been resolved: drm/gud: fix NULL fb and crtc dereferences on USB disconnect On disconnect drm_atomic_helper_disable_all() is called which sets both the fb and crtc for a plane to NULL before invoking a commit. This causes a kernel oops on every display disconnect. Add guards for those dereferences.
UpdatedIn the Linux kernel, the following vulnerability has been resolved: pnfs/flexfiles: Fix memory leak in nfs4_ff_alloc_deviceid_node() In nfs4_ff_alloc_deviceid_node(), if the allocation for ds_versions fails, the function jumps to the out_scratch label without freeing the already allocated dsaddrs list, leading to a memory leak. Fix this by jumping to the out_err_drain_dsaddrs label, which prope
UpdatedIn the Linux kernel, the following vulnerability has been resolved: can: etas_es58x: allow partial RX URB allocation to succeed When es58x_alloc_rx_urbs() fails to allocate the requested number of URBs but succeeds in allocating some, it returns an error code. This causes es58x_open() to return early, skipping the cleanup label 'free_urbs', which leads to the anchored URBs being leaked. As poin
UpdatedIn the Linux kernel, the following vulnerability has been resolved: btrfs: release path before iget_failed() in btrfs_read_locked_inode() In btrfs_read_locked_inode() if we fail to lookup the inode, we jump to the 'out' label with a path that has a read locked leaf and then we call iget_failed(). This can result in a ABBA deadlock, since iget_failed() triggers inode eviction and that causes the
UpdatedIn the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Pass netdev to mlx5e_destroy_netdev instead of priv mlx5e_priv is an unstable structure that can be memset(0) if profile attaching fails.
