| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: Fix command skb lifetime during scan setup
During PA sync scan setup, hci_le_set_ext_scan_param_sync() gets the
address used for the PA_LINK lookup from hci_sent_cmd_data(). The
returned pointer borrows storage from sent_cmd or req_skb, without
holding a reference to either skb.
The scan worker runs on req_workqueue while hci_cmd_work() runs on the
separate device workqueue. After the scan worker loads sent_cmd, the
command worker can free and replace it before hci_sent_cmd_data()
dereferences the skb. The command payload can also be freed between
returning from the helper and comparing the address. The connection
lookup's RCU critical section does not protect the command skb.
KASAN reported:

Use hdev->lock to serialize the address snapshot with sent_cmd
replacement. Protect req_skb replacement and completion cleanup with
the same lock because the helper falls back to that skb. Copy the
address before releasing the lock and use the copy for the existing
RCU-protected connection lookup. Release the mutex before sending or
waiting for commands, preserving the lookup and completion ordering. |

| SeaweedFS is a distributed storage system for files and blobs. From 4.0.388 until 4.41, the SFTP Helm chart embedded one unencrypted Ed25519 private host key in k8s/charts/seaweedfs/templates/sftp/sftp-secret.yaml as stringData.seaweedfs_sftp_ssh_private_key. A standalone deployment presented that public key when sftp.enabled and sftp.enableAuth were true, sftp.existingConfigSecret was not supplied, the legacy sftp.sshPrivateKey path remained selected, a valid config-ssh Secret allowed startup, and hostKeysFolder did not provide a later Ed25519 signer. An attacker able to redirect or intercept client traffic could impersonate that SFTP endpoint to clients that trusted the published host identity, exposing password credentials or data sent to the rogue endpoint. Default all-in-one and non-authenticated standalone paths did not load the key. This issue is fixed in version 4.41. |
