postgresql: PostgreSQL: Arbitrary code execution vulnerability in 'refint' module

A flaw was found in PostgreSQL. A stack buffer overflow in the 'refint' module allows an unprivileged database user to execute arbitrary code as the operating system user running the database. Additionally, a separate vulnerability exists where, if an application uses a user-controlled column as ...

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...

CVE-2026-45253

ptracePTSCREMOTE failed to properly validate parameters for the syscall2 and syscall2 meta-system calls. As a result, a user with the ability to debug a process may trigger arbitrary code execution in the kernel, even if the target process has no special privileges. The missing validation allows ...

CVE-2026-45253

CVE-2026-45253 describes a missing validation in ptrace(PT_SC_REMOTE) related to syscall(2) and __syscall(2) meta-system calls. The issue allows an unprivileged local user who can debug a process to trigger arbitrary code execution in the kernel, potentially gaining full control of the affected s...

CVE-2026-45251

CVE-2026-45251 describes a kernel use-after-free vulnerability: a file descriptor can be closed while a thread is blocked in poll(2)/select(2). The blocked thread does not hold a reference to the underlying object, so freeing the object may occur while the thread is still waiting. In some fd type...

CVE-2026-45250

CVE-2026-45250 concerns a stack buffer overflow in the FreeBSD kernel arising from setcred(2). The unprivileged user can trigger a copyin into a fixed-size kernel-stack array before validating the number of supplementary groups, causing a stack overflow when the list is large. This allows an unpr...

CVE-2026-45250 Stack buffer overflow via setcred(2)

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...
