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...

CVE-2026-89598

A flaw was found in the Linux kernel's fbdev framebuffer device subsystem, specifically within the ssd1307fb driver. This vulnerability occurs when display damage callbacks, which handle updates to the display, perform synchronous I2C Inter-Integrated Circuit transfers from an atomic context. Thi...

CVE-2026-89566

A flaw was found in the Linux kernel's jbd2 component. When the kernel's journaling block device jbd2 processes busy checkpoint buffers, it can skip a crucial rescheduling check. This oversight can lead to prolonged holding of a critical lock, causing other central processing units CPUs to wait...

CVE-2026-89553

A flaw was found in the Linux kernel's nouveau/gem component. A race condition exists where the graphics execution manager GEM close path can close a virtual memory area VMA while an information lookup is still trying to access it. This timing issue leads to a use-after-free vulnerability, which...

CVE-2026-89547

A flaw was found in the Linux kernel's SUNRPC component. A local administrator, under specific conditions of memory pressure or fault injection during RPC server startup, can trigger a failure in per-CPU counter allocation. This failure leads to uninitialized counters, which, when subsequently...

CVE-2026-89515

A flaw was found in the Linux kernel's SCSI core component. When processing data transfers using scatter-gather lists, the system does not properly initialize padding bytes for unaligned data elements. This can result in the exposure of uninitialized memory, potentially allowing a local attacker ...

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...
