CVE-2026-64206

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: cancel pendingrxwork before taking conn-lock l2capconndel takes conn-lock and then calls cancelworksync for pendingrxwork. processpendingrx takes the same mutex, so teardown can deadlock against the worker it is...

CVE-2026-64206

Summary of CVE-2026-64206 : In the Linux kernel Bluetooth L2CAP subsystem, teardown can deadlock due to a circular lock between l2cap_conn_del() and process_pending_rx(). Specifically, l2cap_conn_del() takes conn->lock and then cancels pending_rx_work, while process_pending_rx() may contend fo...

CVE-2026-64189

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: fix race between dump and ipsetlist resize The release path of ipsetdumpdo and ipsetdumpdone read inst-ipsetlist via ipsetrefnetlink, a plain rcudereferenceraw of the array pointer. These run from netlinkrecvmsg...

CVE-2026-64189

CVE-2026-64189 affects the Linux kernel netfilter ipset dump path. A race between dump and ip_set_list resize allows a use-after-free when a concurrent ip_set_create() grows the array and the old one is freed before it is fully dereferenced. The advisory notes that the dump code reads inst->ip...

CVE-2026-64112

A flaw was found in the Linux kernel's Rados Block Device RBD module. A race condition exists in the lockdwork draining mechanism during the unmapping of an image. This allows the lockdwork to be re-queued after it is expected to be finalized, potentially leading to rbdacquirelock executing on...

CVE-2026-64136

A flaw was found in the Linux kernel's Server Message Block SMB client. A missing lock around the tccount increment in the smb2findsmbsesstconunlocked function creates a race condition. This vulnerability, caused by an incomplete refactoring of locking mechanisms, could lead to unexpected behavio...

CVE-2026-64156

A flaw was found in the Linux kernel's network file system netfs and AFS Andrew File System components. When a write operation is skipped due to lock contention and a specific writeback control flag WBSYNCNONE, the system may fail to correctly re-mark the inode, which is a data structure that...

kernel: rtmutex: Use waiter::task instead of current in remove_waiter()

A flaw was found in the Linux kernel. When the kernel's real-time mutex rtmutex component performs a specific operation called 'proxy-lock rollback' during futex requeue, it incorrectly handles task pointers. This can lead to a 'Use-After-Free' UAF vulnerability, where the system attempts to use...
