libssh2: libssh2: Information disclosure and potential arbitrary code execution via heap out-of-bounds read

A missing bounds check in the libssh2 publickey subsystem allows malicious SSH servers to trigger a client-side out-of-bounds read, leaking heap pointers that could enable security bypasses, denial of service, or code execution...

CVE-2026-64451

A flaw was found in the Linux kernel's tracing subsystem. A local user, by manipulating function tracer options, can trigger a NULL pointer dereference in the funcsetflag function. This vulnerability occurs when the active tracer is switched away from the function tracer while a process has an...

CVE-2026-64406

A flaw was found in the Linux kernel's Bluetooth subsystem. This use-after-free UAF vulnerability in the btacceptdequeue function occurs because a temporary reference is prematurely dropped, leading to sockhold accessing freed memory. An attacker could potentially exploit this to cause a denial o...

BIT-OPENBAO-2025-54997 OpenBao: Privileged Operator May Execute Code on the Underlying Host

OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. In versions 2.3.1 and below, some OpenBao deployments intentionally limit privileged API operators from executing system code or making network connections...

CVE-2026-64243

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: simple-mux: Fix enum control bounds check simplemuxcontrolput rejects values greater than e-items, but enum control values are zero based. For the two-entry mux used by this driver, valid values are 0 and 1, so valu...

The vulnerability of the hci_sockbind() function in the net/bluetooth/hci_sock.c module of the Linux kernel’s Bluetooth subsystem allows a attacker to escalate their privileges or cause service failures.

The vulnerability of the hcisockbind function in the net/bluetooth/hcisock.c module of the Linux kernel’s Bluetooth subsystem is related to the reutilization of previously freed memory. Exploiting this vulnerability can allow an attacker to gain increased privileges or cause service failures...
