CVE-2026-45250

The setcred2 system call is only available to privileged users. However, before the privilege level of the caller is checked, the user-supplied list of supplementary groups is copied into a fixed-size kernel stack buffer without first validating its length. If the supplied list exceeds the capaci...

kernel: nfsd: fix heap overflow in NFSv4.0 LOCK replay cache

A flaw was found in the Linux kernel's NFSv4.0 server nfsd. A remote, unauthenticated attacker can exploit this heap overflow vulnerability in the NFSv4.0 LOCK replay cache. By using two cooperating NFSv4.0 clients, where one sets a lock with a large owner string and another requests a conflictin...

kernel: RDMA/umem: Fix double dma_buf_unpin in failure path

A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...

kernel: Read root-owned files as an unprivileged user

A vulnerability was found in the Linux kernel that allows an unprivileged local user to read sensitive files normally restricted to the root user. The flaw occurs during process exit, where a brief window allows an attacker to intercept file access from a privileged process before it fully...

kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...
