CVE-2026-89705

A flaw was found in the Linux kernel's Network File System NFS daemon, nfsd. This vulnerability occurs due to a synchronization issue where a status counter rqstatuscounter is not correctly reset on all exit paths within the nfsddispatch function. This can lead to a race condition where a lockles...

CVE-2026-89667

A flaw was found in the Linux kernel's Network File System Daemon nfsd file caching mechanism. A race condition can occur during concurrent shutdown operations and file disposal, where a file might be unhashed and moved to a dispose list, but the shutdown process misses it. This can lead to a...

CVE-2026-89532

A flaw was found in the Linux kernel's svcrdma component. A remote attacker could send a specially crafted network packet that causes an integer underflow in the pclforeachsegment function when processing a chunk with zero segments. This vulnerability leads to an out-of-bounds read, resulting in ...

CVE-2026-89492

A flaw was found in the Linux kernel's OCFS2 filesystem. A local attacker with the ability to mount a crafted on-disk image could exploit this vulnerability by providing excessive directory-index entry counts when reading metadata. This can lead to an out-of-bounds read, potentially causing...

CVE-2026-89770

A flaw was found in the iomap component of the Linux kernel. This vulnerability occurs when Protection Information PI verification is disabled on a block device, causing fsbiointegrityalloc to not allocate a bio integrity payload. Subsequently, the iomapbioreadfoliorangesync function attempts to...

CVE-2026-89692

A flaw was found in the Linux kernel's Network File System NFS daemon, nfsd. This vulnerability occurs when a delegation recall operation fails, leaving a critical internal flag uncleared. This prevents subsequent attempts to break the same delegation, leading to a denial of service where file...

CVE-2026-89641

A flaw was found in the Linux kernel's Common Internet File System CIFS module. This vulnerability, a use-after-free, occurs in the cifsfilesetsize function. When a file's size is being modified, a critical system resource tcon object can be released too early but then accessed again. A local...

CVE-2026-89635

A flaw was found in ksmbd, a component of the Linux kernel. An authenticated attacker could exploit a use-after-free vulnerability by manipulating durable handles and oplocks during session reconnection. When two sessions hold durable handles on the same file and both disconnect, reconnecting one...

CVE-2026-89441

A flaw was found in the Linux kernel, specifically within the mmc: via-sdmmc driver responsible for managing SD and MultiMediaCard MMC devices. This vulnerability occurs during device removal, where a timing issue allows a process to attempt to access memory that has already been released. This...

CVE-2026-80969

A flaw was found in the Linux kernel's ALSA mpu401 driver. The driver fails to validate the card index when a device is manually bound through the sysfs interface. This oversight can lead to an out-of-bounds memory access. A local attacker with appropriate permissions could exploit this...

CVE-2026-89451

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit SVA Shared Virtual Addressing component. A race condition during the attachment of an SVA handle can lead to a situation where a device pointer is not properly initialized. A local attacker could exploit this flaw by...

CVE-2026-80974

A flaw was found in the mfd: sm501 component of the Linux kernel. This vulnerability arises from a failure to properly free allocated memory for struct sm501devdata during the device removal process. A local attacker could potentially exploit this memory leak, which may lead to a denial of servic...

CVE-2026-89689

A flaw was found in the Linux kernel's Network File System NFS daemon, nfsd. A remote attacker could exploit a use-after-free vulnerability in the nfsd4sequence function. This occurs when the system attempts to reduce the number of active session slots while a client is still using one of the slo...

CVE-2026-89665

A flaw was found in the Linux kernel's nfsd component. A remote attacker could exploit this vulnerability by sending a specially crafted NFSv2 SETATTR or CREATE request with an out-of-range 'useconds' value. This could lead to incorrect timestamps being written to the filesystem, resulting in dat...

CVE-2026-89662

A flaw was found in the Linux kernel's Network File System Daemon NFSD. During client teardown, a race condition can occur where a lock owner is freed while still being referenced, leading to a use-after-free vulnerability. This can result in a NULL dereference, potentially causing a system crash...

CVE-2026-80976

A flaw was found in the Linux kernel's IPv6 Segment Routing seg6 implementation. An unprivileged user can exploit this vulnerability by injecting a specially crafted IPv6 packet. This can lead to an out-of-bounds read, potentially causing a system crash and resulting in a Denial of Service DoS...

CVE-2026-90461

A flaw was found in OpenStack Ironic. When the Image Service is configured for HTTPS Basic Authentication, Ironic may inadvertently transmit a username and password to an unintended remote host. This could lead to the disclosure of sensitive authentication credentials to an attacker who controls...

CVE-2026-89716

A flaw was found in the zram component of the Linux kernel. This vulnerability occurs because the system does not properly validate user-supplied deflate parameters, specifically winbits values. An attacker could exploit this by providing malformed input, which would trigger an internal error BUG...

CVE-2026-89561

A flaw was found in the Linux kernel's IPv6 Routing Protocol for Low-Power and Lossy Networks RPL implementation. A remote attacker could send specially crafted IPv6 packets to a vulnerable system while manipulating the network interface's Maximum Transmission Unit MTU, which defines the largest...

CVE-2026-81008

A flaw was found in the Linux kernel's interconnect subsystem. When a dynamic memory allocation fails during path initialization, an object is prematurely freed while still being referenced in internal lists. This creates dangling pointers, which can be later accessed or modified. This...
