CVE-2026-89713

A flaw was found in the Linux kernel's Network File System Daemon NFSD. A remote attacker, by sending a crafted file attribute modification request SETATTR while a file is being concurrently appended, could exploit a time-of-check to time-of-use TOCTOU vulnerability. This could lead to the...

CVE-2026-89672

A flaw was found in the Linux kernel's Network File System NFS server daemon nfsd. When processing NFSACL version 2 SETACL requests, the system could unintentionally remove a directory's default Access Control List ACL or both access and default ACLs. This occurs because the setposixacl function ...

CVE-2026-89486

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI subsystem. Due to incorrect synchronization during the deallocation of command receiver objects, a use-after-free vulnerability can occur. This allows a freed memory region to be accessed, which could be exploit...

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.
