UNKNOWN

Description

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: reject duplicate wiphy cipher suite entries Duplicate entries in wiphy->cipher_suites do not describe any additional capability, but cfg80211 currently accepts them and leaves individual consumers to deal with them. One such consumer is the WEXT compatibility code, which appends a WEP key length for each WEP cipher entry it sees. Repeated WEP entries can therefore overflow the fixed iw_range::encoding_size array returned by SIOCGIWRANGE. Reject duplicate cipher suite entries in wiphy_register() instead. This keeps the cipher suite invariant in one place and makes malformed wiphy descriptions fail early with -EINVAL, rather than relying on a single cfg80211 user to handle duplicates correctly.

CVE-2026-61742
DBHub is a database MCP server for Postgres, MySQL, SQL Server, Oracle, MariaDB, SQLite. Versions prior to 0.22.5 expose an unauthenticated HTTP MCP endpoint when started with the documented HTTP transport mode, for example `--transport http --port 8080`. The HTTP server attempts to protect browser-origin access by checking whether the `Origin` hostname equals the `Host` hostname, then reflecting the validated `Origin` into `Access-Control-Allow-Origin`. This does not stop DNS rebinding. After an attacker-controlled hostname rebinds to a victim-accessible DBHub HTTP server, both `Origin` and `Host` can contain the attacker-controlled hostname, so DBHub accepts the request and dispatches MCP tool calls. As a result, a malicious website can deterministically invoke DBHub MCP tools from the victim's browser without prompt injection or model involvement. With the default demo configuration this can read and write the demo SQLite database; with a real configured database, the same primitive can read, enumerate, and potentially write database contents depending on DBHub's configured tool permissions and database credentials. Version 0.22.5 fixes the issue.

CVE-2026-61604
The ixo Blockchain is a Layer 1 blockchain that runs on both Testnet and Mainnet. Prior to version 8.0.0, the x/bonds module moved funds from an address that was resolved from a DID verification method, without verifying that the resolved address belonged to the transaction signer. Affected handlers included MsgMakeOutcomePayment, MsgBuy, MsgSell, MsgSwap, and MsgWithdrawShare, as well as the batch order processor. Because any account may list an arbitrary blockchainAccountID as a verification method on a DID it controls (without the consent of that address's owner), an attacker could register victims' addresses as verification methods on their own DID and then move the victims' balances into a bond the attacker controlled — later withdrawing and bridging the proceeds off-chain. This was exploited on ixo mainnet (ixo-5) on 2026-06-20. The attack required no victim keys, signatures, or system compromise — any account holding a balance in a token a bond could use was at risk. This was fixed in v8.0.0, delivered via the on-chain v8 software-upgrade. The x/bonds module is disabled: every bonds message is rejected on all routes (top-level, authz, CosmWasm, and ICA), and the bonds batch EndBlocker is a no-op so no further reserve movements can occur. All node operators and validators must upgrade to v8.0.0. The flaw is in chain state-machine logic and can only be remediated by running the patched binary. There is no application-level workaround. The vulnerability is in consensus logic; remediation requires the network to run the patched (v8.0.0) binary. The bonds module remains disabled in v8.0.0 and will only be re-enabled in a future release once the signer-authorization model has been corrected.

CVE-2026-97521
In the Linux kernel, the following vulnerability has been resolved: gfs2: fix quota init duplicate scan gfs2_quota_init() checks for duplicate quota_change IDs while holding qd_lock and the quota hash bucket bitlock. That path used gfs2_qd_search_bucket(), which takes a lockref reference via lockref_get_not_dead(). On PREEMPT_RT this may sleep, which is not allowed under the bucket bitlock, triggering "sleeping function called from invalid context". Use a no-ref bucket lookup in this path, then continue duplicate handling without taking a lockref there. Refactor gfs2_qd_search_bucket() to build on top of the no-ref helper so lookup traversal stays in one place. This patch fixes a bug reported by syzbot.

CVE-2026-97520
In the Linux kernel, the following vulnerability has been resolved: gfs2: move quota_init qc iterator increment Move qc++ from the loop body into the for-loop increment expression in gfs2_quota_init(). This keeps iterator progression explicit and avoids mixing pointer advance with duplicate-slot handling in the loop body.

CVE-2026-97519
In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix null pointer dereference in devcoredump cleanup In xe_devcoredump_snapshot_free(), ss->gt may be NULL when the snapshot was never fully populated (e.g., when cleanup is triggered without a prior capture). Guard the xe_guc_capture_put_matched_nodes() call with IS_ERR_OR_NULL() to prevent a null dereference. In xe_devcoredump_free(), the deferred work is only queued when a coredump is captured, so guard cancel_work_sync() with a check on coredump->captured.
