EUVD-2026-49783
Accesses to the CMOS memory contents are done using an indirect IO port pair. Therefore Xen needs to cache the guest chosen index, and one of the usages of the index didn't take the necessary locking to avoid concurrent changes. As a result, a guest could change the index after it being checked,...
CVE-2026-64433
A flaw was found in the Linux kernel's Bluetooth Management MGMT subsystem. A use-after-free UAF vulnerability exists in the adddevicecomplete function. This occurs because the function does not properly acquire a lock before accessing connection parameters, allowing a concurrent device removal...
UBUNTU-CVE-2026-64218
In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: fix reportwork leak on backbonegw purge batadvblapurgebackbonegw removes stale backbone gateway entries, but fails to properly handle their associated reportwork: - If reportwork is running, the purge must wait f...
CVE-2026-64305
In CVE-2026-64305, the Linux kernel crypto: qat path is fixed by ensuring the service_table is protected with service_lock during all iterations (in adf_dev_init/start/stop/shutdown, adf_dev_restarting_notify/restarted_notify, and adf_error_notifier). Several list_walks previously occurred withou...
CVE-2026-64077
A flaw was found in the Linux kernel's netfilter ebtables component. A concurrency issue exists during the two-stage removal scheme where the table-ops assignment could expose a partially-filled table structure if the ebt mutex is not held. This could lead to unpredictable system behavior...
kernel: md/bitmap: fix GPF in write_page caused by resize race
A flaw was found in the Linux kernel's md/bitmap component. This vulnerability involves a use-after-free race condition that occurs during array resize operations. When the bitmapdaemonwork and bitmapresize functions execute concurrently, they can access memory pages that have already been freed...
CVE-2026-53518
Better Auth is an authentication and authorization library for TypeScript. From 1.6.0 until 1.6.11, the @better-auth/oauth-provider POST /oauth2/token endpoint for the authorizationcode grant redeems a single-use authorization code through a non-atomic find-then-delete sequence, allowing two...
kernel: eventpoll: defer struct eventpoll free to RCU grace period
A flaw was found in the Linux kernel's eventpoll component. In certain situations, the epfree function in eventpoll.c can prematurely free the eventpoll data structure while it is still being used by another concurrent thread. This use-after-free UAF vulnerability could allow a local attacker to...
kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result
A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...
CVE-2026-10653
The Zephyr netbuf library lib/netbuf/buf.c manipulated both of its reference counts -- the per-header buf-ref and the per-data-block refcount at the start of each variable/heap data allocation -- with plain non-atomic C operators buf-ref++, if --buf-ref 0, if --refcount. The API is documented as...
CVE-2026-53303
In the Linux kernel, the following vulnerability has been resolved: f2fs: protect extensionlist reading with sblock in f2fssbishow In f2fssbishow, the extensionlist, extensioncount and hotextcount are read without holding sbi-sblock. If a concurrent sysfs store modifies the extension list via...

Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: smb: client: prevented races in -queryinterfaces It was possible for two query interfaces to simultaneously attempt to update the interfaces. This issue can be avoided by checking and updating ifacelastupdate under ifacelock...
kernel: Bluetooth: hci_event: fix potential UAF in SSP passkey handlers
A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a Use-After-Free UAF, exists within the Secure Simple Pairing SSP passkey handlers. It occurs when hciconn lookup and field access are performed without proper locking, allowing a connection to be freed concurrently...
GHSA-4VRG-R928-H5VV SpiceDB: Checks involving relations with caveats can result in unconditional permission when conditional permission is expected
Impact Under concurrency, CheckPermission and CheckBulkPermissions can return PERMISSIONSHIPHASPERMISSION for a resource, permission, subject whose correct answer is PERMISSIONSHIPCONDITIONALPERMISSION. You are impacted if all of the following hold: 1. Your schema has a permission combining...
Concurrent Ruby - ReadWriteLock allows wrong-thread write release and stray read-release counter corruption
Summary Concurrent::ReadWriteLockreleasewritelock does not verify that the calling thread acquired the write lock. Any thread with access to the lock object can release an active write lock held by another thread. A second writer can then enter its critical section while the first writer is still...

CVE-2026-45977
The CVE-2026-45977 issue affects the Linux kernel fbnic driver. A race in handling firmware logs can cause a use‑after‑free: fw_log is written in fbnic_fw_log_write() and can be accessed from the mailbox handler fbnic_fw_msix_intr(), but the log data is freed during IRQ/MBX teardown, potentially ...
@sveltejs/kit: `query.batch` cross-talk
