CVE-2026-89457

A flaw was found in the s390/dasd component of the Linux kernel. An unprivileged local user can trigger a null pointer dereference by reading specific world-readable sysfs attributes while the device is being brought online. This can lead to a kernel panic, resulting in a denial of service...

CVE-2026-81016

A flaw was found in the Linux kernel. Specifically, within the AMD Platform Management Controller PMC component, the amdstbs2dinit function does not properly validate memory addresses returned by System Management Unit SMU commands. This can result in the kernel attempting to map a critical memor...

CVE-2026-80997

A flaw was found in the Linux kernel's IP Accelerator IPA network driver. Specifically, the ipastartxmit function incorrectly manages the transmit TX queue during a device's runtime resume process. This can lead to the TX queue stopping permanently because the mechanism intended to restart it is...

CVE-2026-80994

A flaw was found in the Open vSwitch component of the Linux kernel. A local attacker could exploit a use-after-free vulnerability during flow deletion. This occurs due to a race condition where the flow mask is freed prematurely, allowing subsequent operations to access deallocated memory...

CVE-2026-80992

A flaw was found in the net: ravb component of the Linux kernel. This vulnerability allows for a NULL pointer dereference when the Precision Time Protocol PTP clock's index is queried before it is properly initialized or if its registration fails. This issue could lead to a system crash, resultin...

CVE-2026-80957

A flaw was found in the dm-pcache component of the Linux kernel. A local attacker could exploit a vulnerability in the cachereplay function, which does not properly handle a forged last-kset chain. By crafting a malicious chain that points back to an already visited segment, an attacker can cause...

CVE-2026-89634

A flaw was found in the Server Message Block SMB client within the Linux kernel. An integer overflow in the ALIGN function, specifically within the symlinkdata error context loop, can lead to an out-of-bounds read. This issue allows a malicious SMB server to cause a denial of service DoS by...

CVE-2026-89569

A flaw was found in the Linux kernel's Bluetooth RFCOMM subsystem. This vulnerability arises because the system does not properly manage memory when handling Bluetooth security confirmations. A race condition allows a part of the system to free memory that is still in use by another part, leading...

CVE-2026-89543

A flaw was found in the kernel's sunrpc component. A use-after-free vulnerability can occur due to improper handling of clnt-pipefssb pointers during mount and unmount events. This can lead to stale pointers, which, when accessed, may result in a system crash Denial of Service...

CVE-2026-89533

A flaw was found in the svcrdma component of the Linux kernel. Incorrect offset arithmetic in the svcrdmareadchunkrange function can lead to a u32 underflow. This underflow can cause the system to attempt to allocate a large amount of memory, potentially resulting in a Denial of Service DoS due t...

CVE-2026-89476

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending specially crafted duplicate RECONF responses. This action can cause an underflow in the stream-outcnt counter, potentially leading to unexpected system...

CVE-2026-89643

A flaw was found in the Linux kernel's audit subsystem. When fsnotify rules are automatically removed, the system incorrectly manages memory references, leading to a situation where freed memory can be accessed again. This memory corruption vulnerability could allow a local attacker to cause a...

CVE-2026-89626

A flaw was found in the Linux kernel's Human Interface Device HID sensor custom driver. When creating sysfs groups for custom sensor fields, the hidsensorcustomaddattributes function fails to properly clean up previously created groups if an error occurs. This improper resource management could...

CVE-2026-89593

A flaw was found in the Linux kernel's huge page hugetlb subsystem. This vulnerability occurs when a huge page of memory is shared between a parent and a child process. If the parent process unmaps the huge page before the child, the system can incorrectly reduce the count of reserved huge pages...

CVE-2026-89555

A flaw was found in the Linux kernel's Multiprotocol Label Switching MPLS subsystem. When processing specially crafted Geneve packets through an MPLS multipath setup, a use-after-free vulnerability occurs. This issue arises because a cached header pointer hdr is not reloaded after pskbmaypull...

CVE-2026-89529

A flaw was found in the Linux kernel's svcrdma component, which handles Remote Procedure Call over Remote Direct Memory Access RPC/RDMA Read operations. This vulnerability occurs because the Read list decoder does not properly validate the lengths of incoming data segments. An attacker could send...

CVE-2026-89518

A flaw was found in the Linux kernel's schedext component. Under core scheduling, incorrect assumptions in dispatch kfuncs regarding thisrq can lead to a deadlock. This occurs when an rq lock is acquired on a CPU different from the dispatched rq's, potentially causing the system to become...

CVE-2026-89503

A flaw was found in the Linux kernel's ring-buffer component. A race condition exists in the ringbufferallocreadpage function when it interacts with ringbuffersubbuforderset. This can lead to an incorrect memory allocation where the buffer page's order bpage-order does not match the actual...

CVE-2026-89534

A flaw was found in the Linux kernel's svcrdma module. This vulnerability occurs when the system attempts to handle an RDMA Remote Direct Memory Access address change, and a critical memory allocation fails. This can lead to a 'use-after-free' error, where the system tries to access memory that h...
