Linux Distros Unpatched Vulnerability : CVE-2026-90176

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ksmbd: Do not skip lock checks for single-byte ranges checklockrange uses inclusive ranges. Its callers pass the end offset as start + length - 1, so start == e...

CVE-2026-92520

In the Linux kernel, the following vulnerability has been resolved: bpf: Zero queue and stack outputs on lock failure Queue and stack pop/peek helpers accept an uninitialized output buffer because the verifier expects the helper to initialize it. The empty-map error path clears the buffer, but a...

DEBIAN-CVE-2026-90432

In the Linux kernel, the following vulnerability has been resolved: schedext: Abort directly from the hardlockup handler scxhardlockup defers the abort to an irqwork because exit claiming used to take scxschedlock and couldn't run from NMI. The deferral is now unnecessary - claiming is NMI-safe a...

DEBIAN-CVE-2026-90338

In the Linux kernel, the following vulnerability has been resolved: serial: amba-pl011: keep console clock enabled for atomic writes pl011consolewriteatomic runs from nbcon atomic context, where sleeping is not allowed. It calls clkenable, which takes the common-clk enablelock. Under PREEMPTRT th...
