CVE-2026-63946

CVE-2026-63946: In the Linux kernel Bluetooth ISO path, iso_recv_frame can use a freed sk due to holding iso_conn_lock but releasing it before using conn->sk. The fix replaces a bare pointer read with iso_sock_hold(conn), which holds the sock while the spinlock is still held and atomically inc...

CVE-2026-53380

CVE-2026-53380 affects the Linux kernel media component rzv2h-ivc. The vulnerability arises from concurrent access to the internal buffer list rzv2h_ivc::buffers.queue: in rzv2h_ivc_transfer_buffer(), a list_del() occurs without holding the spinlock rzv2h_ivc::buffers.lock, allowing concurrent mo...

kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_conn_usage_count()

A use-after-free flaw was found in the Linux kernel's iSCSI target subsystem. In the iscsitdecconnusagecount function, complete is called while still holding the conn-connusagelock spinlock. The waiting thread such as iscsitcloseconnection may wake up immediately and free the iscsitconn structure...

CVE-2026-53197

A flaw was found in the iptfs module of the Linux kernel. This issue, an ABBA deadlock, occurs when iptfsdestroystate attempts to cancel a timer while holding a spinlock that the timer's callback also tries to acquire. This circular dependency can cause the system to become unresponsive, leading ...
