CVE-2026-11564: Improper Certificate Validation

libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. An easy handle that first uses default native CA trust can continue trusting the native platform store after the application switches that same handle to custom CA...

libcurl: libcurl: Certificate validation bypass due to incorrect connection reuse

A flaw was found in curl. When libcurl reuses a connection from its connection pool, an easy handle that initially used default native Certificate Authority CA trust may continue to trust the native platform store. This occurs even after the application has switched that same handle to custom CA...

Linux Distros Unpatched Vulnerability : CVE-2026-55223

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - c3p0 is a JDBC Connection pooling library. In versions prior to 0.14.0, c3p0 in combination with other libraries, can compose to a sink for deserialization...

CVE-2026-53327

A flaw was found in the Linux kernel's debugobjects functionality. On systems with Real-Time RT enabled kernels, the fillpool function can lead to a system assertion if a task is already blocked on a lock, causing corruption of the priority inheritance chain. This issue can result in a Denial of...

CVE-2026-53327

In the Linux kernel, the following vulnerability has been resolved: debugobjects: Do not fillpool if piblockedon On RT enabled kernels, fillpool ends up calling rtlocklock, which asserts if current::piblockedon is set, because a task can obviously only block on one lock as otherwise the priority...

CVE-2026-53327

Summary: CVE-2026-53327 affects the Linux kernel in the debugobjects path where fill_pool() may interact with rtlock_lock() if current::pi_blocked_on is set on RT-enabled kernels. The connected records confirm concrete remediation across several distributions via patched kernel packages or rootio...
