Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a security flaw in the call to the connect function from the cfg802.11 layer when lockdep is enabled...

kernel: SMB3: Add missing locks to protect deferred close file list

In the Linux kernel, the following vulnerability has been resolved: SMB3: Add missing locks to protect deferred close file list cifsdeldeferredclose function has a critical section which modifies the deferred close file list. We must acquire deferredlock before calling cifsdeldeferredclose functi...

kernel: net/mlx5e: Check for NOT_READY flag state after locking

A race condition was found in the Linux kernel Mellanox mlx5 network driver's traffic control offload flow management. A local user with privileges to configure traffic control flower filters can trigger concurrent flow deletion operations where the NOTREADY flag is checked before acquiring the...

kernel: iommufd: IOMMUFD_DESTROY should not increase the refcount

A race condition was identified in the iommufd subsystem of the Linux kernel where the IOMMUFDDESTROY command incorrectly increments an object’s reference count without holding the expected exclusive synchronization destroyrwsem. This violates the assumption that temporary reference count...

kernel: Bluetooth: Fix possible deadlock in rfcomm_sk_state_change

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix possible deadlock in rfcommskstatechange syzbot reports a possible deadlock in rfcommskstatechange 1. While rfcommsockconnect acquires the sk lock and waits for the rfcomm lock, rfcommsockrelease could have the...

kernel: Bluetooth: L2CAP: Fix potential user-after-free

A use-after-free flaw was identified in the Linux kernel’s Bluetooth L2CAP implementation. In certain conditions, when allocating a socket buffer via allocskb, the kernel may release and later reacquire the channel lock; if the channel is disconnected in the meantime, a subsequent reference to th...

kernel: mptcp: fix disconnect vs accept race

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix disconnect vs accept race Despite commit 0ad529d9fd2b "mptcp: fix possible divide by zero in recvmsg", the mptcp protocol is still prone to a race between disconnect or shutdown and accept. The root cause is that the...

kernel: net/mlx5e: Take RTNL lock when needed before calling xdp_set_features()

A locking flaw in the Mellanox mlx5 Ethernet driver allowed calls to xdpsetfeatures without holding the required rtnetlink RTNL lock. A local administrator switching device profiles for example, from an uplink representor to a Network Interface Card profile could trigger notifier paths without...

kernel: dm: don't attempt to queue IO under RCU protection

A sleep-in-atomic-context bug was found in the Device Mapper subsystem in the Linux kernel. When processing REQNOWAIT requests, dm incorrectly submits I/O while holding an RCU read lock, assuming that REQNOWAIT means no scheduling can occur. However, mempoolalloc and other allocation functions ma...

kernel: ext4: avoid deadlock in fs reclaim with page writeback

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid deadlock in fs reclaim with page writeback Ext4 has a filesystem wide lock protecting ext4writepages calls to avoid races with switching of journalled data flag or inode format. This lock can however cause a deadlock...
