CVE-2026-98559

A flaw was found in the Linux kernel's Shared Memory Communications SMC subsystem. When processing port errors, the kernel traverses active link groups without holding the appropriate lock, allowing a concurrent termination event to free memory while it is still in use. An attacker capable of...

CVE-2026-98556

A flaw was found in the Linux kernel's Google Virtual NIC gve driver. A local user with raw packet access or an adjacent guest system can trigger a Denial of Service DoS by sending network packets with an excessively large segment size. The driver fails to validate the Maximum Segment Size MSS...

CVE-2026-98555

A flaw was found in the Linux kernel's Logical Link Control LLC subsystem. When an error occurs during network packet header initialization, the kernel mistakenly frees the incorrect memory buffer, resulting in a use-after-free condition, a double-free, and memory leaks. An attacker could exploit...

CVE-2026-98557

A flaw was found in the Google Virtual Ethernet gve driver in the Linux kernel. This vulnerability may allow a local attacker to cause a Denial of Service DoS by transmitting network traffic that uses User Datagram Protocol UDP Generic Segmentation Offload GSO. Because the driver improperly...

CVE-2026-98558

A flaw was found in the Linux kernel's networking subsystem. When a central processing unit CPU is taken offline, pending network packet buffers held in deferred processing queues are not properly flushed. A privileged local user or administrative action offlining a CPU during network device...

CVE-2026-98553

A flaw was found in the Linux kernel's automount file system autofs. A local user can trigger this issue by initiating an autofs mount operation that fails during initialization, causing the kernel to fail to release associated pipe file references. Repeated exploitation can permanently leak syst...

CVE-2026-98552

A flaw was found in the Linux kernel's Performance Counters for Linux perf subsystem. A race condition during the attachment of performance monitoring context data can cause the kernel to fail to update tracking flags, resulting in a reference count leak. A local attacker could exploit this...

CVE-2026-98554

A flaw was found in the Linux kernel's virtual local area network VLAN driver. When processing network packets that lack sufficient reserved buffer space headroom before network headers are appended, the system triggers a panic condition. An attacker could exploit this vulnerability to cause a...

CVE-2026-98551

A flaw was found in the Linux kernel's Performance Events perf subsystem on ARM64 architectures. This flaw allows a local user to cause an information disclosure of sensitive kernel memory. The issue occurs because certain branch tracking data structures are not properly cleared, allowing an...

CVE-2026-98549

A flaw was found in the Linux kernel's TCP subsystem. When a TCP connection transitions to hardware-assisted encryption, data packets queued after the transition can be improperly merged with unencrypted packets in the retransmission queue. This issue may allow an attacker on the network to obtai...

CVE-2026-98550

A flaw was found in the TIPC Transparent Inter-Process Communication subsystem of the Linux kernel. This flaw allows an attacker to cause a Denial of Service DoS by sending unexpected or duplicate group acknowledgment messages. Due to improper validation of incoming protocol messages, an internal...

CVE-2026-98548

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker or an unprivileged local user could trigger a Denial of Service DoS or memory corruption by sending specially crafted packets containing bundled error and data chunks. This issue...
