CVE-2026-89446

A flaw was found in the Linux kernel's iommufd component. When the system attempts to store an Input/Output Address Space IOAS object and the storage operation fails, the IOAS object's associated resources, such as its write lock and object reference, are not properly released. This oversight can...

CVE-2026-81010

A flaw was found in the Linux kernel's iouring/waitid component. The iowaitidcb function, when running from a kernel worker, fails to properly acknowledge task work cancellation. This oversight causes the dowait function to execute within an incorrect task context, which is critical as waitid...

CVE-2026-80981

A flaw was found in the Linux kernel's net/smc component. A local attacker could exploit a use-after-free vulnerability in the smcllcsrvaddlink function, where a freed memory region is improperly accessed. This can lead to memory corruption and potentially result in a denial of service DoS...

CVE-2026-80971

A flaw was found in the ALSA bcd2000 driver of the Linux kernel. When a USB device using this driver is disconnected while a rawmidi substream is still active, the driver fails to clear the Universal Serial Bus Request Block URB pointers. This oversight allows a local attacker to trigger a...

CVE-2026-80958

A flaw was found in the dm-pcache component of the Linux kernel. The tail-kset read operations, used by cachereplay, the writeback worker, and the garbage collection GC worker, incorrectly calculate the length of the data region. This error causes the system to read beyond the intended segment da...

CVE-2026-89690

A flaw was found in the nfsd component of the Linux kernel. This vulnerability, a use-after-free, occurs when a specific memory buffer is prematurely released while another process is still trying to access it. This timing issue can lead to memory corruption. This could result in a system crash...

CVE-2026-89686

A flaw was found in the Linux kernel's Network File System Daemon nfsd for NFSv4 layouts. A race condition allows a remote attacker to trigger a kernel panic, leading to a Denial of Service DoS. This occurs when the nfsd4alloclayoutstateid function accesses a file pointer without proper locking...

CVE-2026-89679

A flaw was found in the Linux kernel's nfsd component. A remote attacker can exploit this by sending a specially crafted SETATTR request that includes specific delegation timestamp attributes and a special NFSv4 state ID. This triggers a null dereference, leading to a kernel crash and a Denial of...

CVE-2026-89660

A flaw was found in the Linux kernel's Network File System Daemon NFSD. This vulnerability, a use-after-free, occurs during the revocation of client administrative states. A race condition can allow a client's memory to be freed prematurely while still being referenced, potentially leading to...

CVE-2026-89652

A flaw was found in the Linux kernel's Ceph file system. A malicious or compromised Ceph Metadata Server MDS can send a specially crafted LOOKUPNAME reply that causes a buffer overflow when copying dentry names during an NFS export operation. This out-of-bounds write can lead to memory corruption...

CVE-2026-89596

A flaw was found in the Linux kernel's forcedeth driver. An off-by-one error in the nvsuspend and nvresume functions, which handle saving and restoring non-PCI configuration space, can lead to an out-of-bounds memory access. This occurs during system suspend and resume operations. If specific...

CVE-2026-89511

A flaw was found in the qede driver in the Linux kernel. Under specific memory pressure conditions, the driver can encounter a NULL pointer dereference when processing network traffic using TPA TCP Segmentation Offload continuation fragments. This issue stems from an uninitialized data pointer,...

CVE-2026-89495

A flaw was found in ocfs2 in the Linux kernel. A malicious or compromised node within a Distributed Lock Manager DLM cluster can send specially crafted messages with unchecked length fields. This can lead to a heap out-of-bounds write, potentially allowing for arbitrary code execution, or an...

CVE-2026-89489

A flaw was found in the Linux kernel. The sysor1katomic syscall, specific to the openrisc architecture, does not adequately validate user-provided pointers. An unprivileged process can exploit this by supplying kernel addresses to the syscall, gaining unauthorized read and write access to kernel...

CVE-2026-80936

A flaw was found in the Linux kernel's mt7925 Wi-Fi driver. During multi-link power-save setup, the mlopmwork is queued with a delay but not properly cancelled when the device is stopped. This can lead to the work item attempting to access a deallocated workqueue, resulting in a kernel warning an...

CVE-2026-89654

A flaw was found in the Ceph file system component of the Linux kernel. A race condition exists in the checknewmap function during session handling. This allows a local attacker to exploit a use-after-free vulnerability by freeing a session while another thread attempts to access it. This could...

CVE-2026-89648

A flaw was found in the Linux kernel's Ceph client. A malicious or compromised Ceph Metadata Server MDS could send a specially crafted reply with an unbounded number of delegated inode intervals. This could cause the client to enter an infinite loop or exhaust memory resources, leading to a denia...

CVE-2026-89644

A flaw was found in the Linux kernel's btrfs filesystem. When performing direct I/O writes in a NOCOW No Copy-On-Write range, an extent map reference may not be properly released if an error occurs during extent creation. This oversight can lead to an extent map leak, potentially causing memory...

CVE-2026-89630

A flaw was found in the Linux kernel's Server Message Block SMB client. An incorrect calculation of the dataoffset bound in the isvalidoplockbreak function can lead to a read overflow. This vulnerability allows a malicious SMB server to potentially trigger an out-of-bounds read, which could resul...

CVE-2026-89624

A flaw was found in the Linux kernel's universal-pidff driver. This vulnerability occurs when the force-feedback initialization fails, leaving a hidraw character device active. A local attacker can exploit this by opening the device, leading to a use-after-free condition where the system attempts...
