CVE-2026-89687

A flaw was found in the Linux kernel's Network File System Daemon nfsd. The nfsdfiledoacquire function might attempt to use a file that has not been fully opened, as the -atomicopen operation could return success prematurely. While this scenario is considered highly improbable, it could lead to...

CVE-2026-89684

A flaw was found in the Linux kernel's nfsd component. A remote attacker, by sending a specially crafted OFFLOADCANCEL request, could exploit a race condition during the initialization of copy state notifications. This could lead to a denial of service DoS by causing the server to crash...

CVE-2026-89650

A flaw was found in the Linux kernel's Ceph client. A malicious or compromised Ceph monitor, or an on-path attacker, can send a specially crafted Metadata Server MDS map. This map, with an oversized numexporttargets field and a per-MDS info version of 2 or 3, can trigger an out-of-bounds read in...

CVE-2026-89516

A flaw was found in the Linux kernel's schedext component. When a Deferred Scheduling Queue DSQ is destroyed, a pending deferred re-enqueue DRU operation might still attempt to access the destroyed DSQ. This can lead to a BUGON condition, causing a kernel panic and resulting in a Denial of Servic...

CVE-2026-89504

A flaw was found in the Linux kernel's regulator subsystem. This vulnerability arises from a programming error where a device tree node pointer is released too early, creating a "dangling pointer"—a reference to memory that is no longer valid. This can lead to system instability, potentially...

CVE-2026-89475

A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the bq24257 power supply driver. This issue occurs when the STAT-pin interrupt handler attempts to reschedule work and access memory that has already been freed during the device removal process. This can lead to syste...

CVE-2026-89464

A flaw was found in the Linux kernel's twl4030charger driver. When the driver's remove function is called, it fails to properly cancel pending worker tasks. This oversight allows a worker to attempt to access memory that has already been deallocated, leading to a use-after-free vulnerability. A...

CVE-2026-89467

A flaw was found in the Linux kernel's qcombattmgr component. This flaw is a use-after-free vulnerability that occurs because the qcombattmgrpdrnotify function can queue enablework even after the associated battmgr object has been deallocated. A local attacker could exploit this by triggering the...

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-2026-80981

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-2026-89690

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-2026-89679

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-2026-89596

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-2026-48490 ArduinoCore-AVR: Stack-Based Buffer Overflow in String float/double concatenation handler

ArduinoCore-avr contains the source code and configuration files of the Arduino AVR Boards platform. A vulnerability in versions prior to 1.8.8 allows an attacker to trigger a stack-based buffer overflow when concatenating floating-point values of sufficiently large magnitude onto an Arduino Stri...

CVE-2026-48490

ArduinoCore-avr (the source code and configuration files of the Arduino AVR Boards platform) contains a stack-based buffer overflow in its floating-point concatenation path. Versions prior to 1.8.8 are affected. Passing values near the extremes of the float or double range to String::concat(float...

CVE-2026-48490 ArduinoCore-AVR: Stack-Based Buffer Overflow in String float/double concatenation handler

ArduinoCore-avr contains the source code and configuration files of the Arduino AVR Boards platform. A vulnerability in versions prior to 1.8.8 allows an attacker to trigger a stack-based buffer overflow when concatenating floating-point values of sufficiently large magnitude onto an Arduino Stri...

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...
