CVE-2026-89695

A flaw was found in the Linux kernel's Network File System Daemon nfsd. The nfsd4decodeposixacl function, responsible for decoding POSIX Access Control Lists ACLs, does not properly cap the entry count received from a client. A remote attacker can exploit this by sending a specially crafted ACL...

CVE-2026-89578

A flaw was found in the Linux kernel's device mapper I/O dm-io component. When handling DMIOBIO requests, incorrect sector-based accounting for misaligned direct I/O buffers could lead to an infinite loop. This issue can cause I/O operations to hang indefinitely, resulting in a denial of service...

CVE-2026-89751

A flaw was found in the Linux kernel's x86/tdx component. An off-by-one error in the handlein and handleout functions, specifically in the GENMASK calculation for port I/O operations, causes the mask to be one bit too wide. This incorrect handling of I/O sizes could potentially lead to unintended...

CVE-2026-89644

A flaw was found in the Linux kernel's btrfs filesystem. When performing direct I/O writes in a NOCOW No Copy-On-Write range, an extent map reference may not be properly released if an error occurs during extent creation. This oversight can lead to an extent map leak, potentially causing memory...
