CVE-2026-12633

The IPv6 neighbor-discovery code in subsys/net/ip/ipv6nbr.c processes the 6LoWPAN Context Option 6CO, RFC 6775 carried inside ICMPv6 Router Advertisements. In handlera6co the 8-bit contextlen field is taken directly from the packet and was never bounded to the RFC maximum of 128. The function...

CVE-2026-74265

A flaw was found in the mana network driver of the Linux kernel. When creating a General DMA GDMA queue, the queue-id may not be properly initialized. If the queue creation fails before a valid ID is assigned, a subsequent cleanup operation can incorrectly use a zero ID, potentially corrupting th...

CVE-2026-74263

A flaw was found in the Linux kernel's Wireless Wide Area Network WWAN t7xx driver. The t7xxportctrltx function, which handles control transmissions, fails to validate the return value of skbclone. An attacker with local access could exploit this by triggering a scenario where skbclone returns a...

CVE-2026-74539

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. A missing lock in a critical function allows for concurrent access to internal data structures without proper synchronization. This concurrency issue could lead to system instability or a denial of service, impacting the availability...

CVE-2026-74522

A flaw was found in ksmbd, a component of the Linux kernel. This use-after-free vulnerability occurs when a ksmbd file object is prematurely freed while another session still holds a reference to it. This can lead to the system attempting to access freed memory, potentially causing a system crash...

CVE-2026-74520

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit and IOMMUFD IOMMU File Descriptor components. This vulnerability is a Use-After-Free UAF, which means the system attempts to use memory that has already been released. Specifically, during device detachment or hardwa...

CVE-2026-74485

A flaw was found in the binfmtmisc component of the Linux kernel. An unprivileged local user, operating within a user namespace, could exploit this vulnerability. By registering a binfmtmisc string where the chosen delimiter character is also a flag character, the system's flag field parser can...

CVE-2026-74264

A flaw was found in the Linux kernel's network watchdog component. A race condition in the reference count tracking mechanism, specifically between netdevwatchdogup and devwatchdog, allows for concurrent overwriting or freeing of reference tracking information. This can lead to list corruption an...

CVE-2026-74547

A flaw was found in the Linux kernel's hwmon adt7470 component. A local user can exploit this by configuring the 'autoupdateinterval' to zero via sysfs while 'numtempsensors' is also set to zero. This combination forces the background thread into an unbounded busy-loop, consuming CPU resources an...

CVE-2026-74551

A flaw was found in the Linux kernel's hwmon: nzxt-smart2 driver. This vulnerability allows for immediate and deterministic memory corruption on systems with non-coherent CPU architectures, such as ARM or MIPS. When operations like setting a fan speed or updating an interval trigger a USB Direct...

CVE-2026-74541

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. This vulnerability arises from the system's failure to properly clear isodata when a connection is detached from its host controller connection hcon. A local attacker could exploit this use-after-free condition to cause a denial of...

CVE-2026-74260

A flaw was found in the Linux kernel's netfilter component, specifically within the nfdupnetdev module. This vulnerability arises from an imbalanced decrementation of recursion counters when network packets are transmitted, particularly during a possible migration to a different CPU. This imprope...

CVE-2026-74259

A flaw was found in the Linux kernel's Common Internet File System CIFS implementation. A local user could trigger a null pointer dereference by unmounting a CIFS share while certain files are still being processed. This could lead to a system crash, resulting in a denial of service...

CVE-2026-74257

A flaw was found in the Linux kernel's sockmap feature. The udpbpfrecvmsg function, responsible for handling message reception, lacks proper serialization for skmsg objects. This allows multiple threads to access and modify the same skmsg object concurrently, resulting in a use-after-free...

CVE-2026-72502

A flaw was found in the Linux kernel. When processing TCP IPv6 packets with a large Maximum Transmission Unit MTU, a specific calculated Maximum Segment Size MSS value can conflict with an internal flag GSOBYFRAGS. A local attacker could send a specially crafted TCP packet that, when processed,...

CVE-2026-72500

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA Broadcom NetXtreme-E bnxtre driver. This use-after-free vulnerability occurs because a specific memory page is released prematurely during the teardown process. A local attacker could exploit this timing issue, potentially...

CVE-2026-74560

A flaw was found in the Linux kernel's AFXDP Address Family eXpress Data Path subsystem. When handling multi-buffer transmissions, the xskdropskb function incorrectly cancels completion queue CQ reservations without submitting buffer addresses to the CQ. This leads to a buffer leak where userspac...
