CVE-2026-63974 Bluetooth: hci_sync: Set HCI_CMD_DRAIN_WORKQUEUE during device close

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: Set HCICMDDRAINWORKQUEUE during device close Since hcidevclosesync can now be called during the reset path, we should also set HCICMDDRAINWORKQUEUE. This avoids queuing timeouts while the hdev workqueue is bei...

CVE-2026-63974

CVE-2026-63974 affects the Linux kernel Bluetooth subsystem. The issue arises in hci_sync where HCI_CMD_DRAIN_WORKQUEUE must be set during device close because hci_dev_close_sync() can be invoked on a reset path, preventing timeouts from being queued while the hdev workqueue drains. The consequen...

CVE-2026-63913

The CVE-2026-63913 entry concerns the Linux kernel netfilter conntrack TCP state machine. A crafted RST with an invalid SEQ after observing a SYN could transition the conntrack entry to TCP_CONNTRACK_CLOSE, even if the RST is not a valid response to the observed SYN or its direction. This could p...

kernel: ALSA: aloop: Fix peer runtime UAF during format-change stop

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture aloop driver. This Use-After-Free UAF vulnerability occurs when loopbackcheckformat stops the capture side during a format change, while a concurrent close operation detaches or frees the runtime. An attacker could...

netty-codec-redis: Netty's Lack of Lifecycle Cleanup Leads to Pooled ByteBuf Leak in RedisArrayAggregator

A flaw was found in netty-codec-redis. A remote attacker can exploit this vulnerability by repeatedly closing Redis pipeline connections before a Redis array aggregate completes. This leads to a permanent leak of direct-memory buffers, which prevents memory chunks from being returned to the share...
