popt-devel: popt-static: Off-by-one in poptStuffArgs

A flaw was found in popt, a command-line option parsing library. An off-by-one error in the poptStuffArgs function, when repeatedly called by a host application or through deep alias nesting, can lead to corruption of internal program data. This corruption could potentially enable a local attacke...

CVE-2026-72339

A flaw was found in the Linux kernel's qede component, which handles network device operations. Under specific memory pressure conditions, an error in how network buffer descriptors BDs are managed can lead to an off-by-one issue. This desynchronizes the BD ring, potentially corrupting memory and...

CVE-2026-12520

In Zephyr RTOS v4.4.0 and earlier, the HL7800 modem driver's ~20 AT-response handlers write into a 128-byte stack buffer. The +KCELLMEAS handler passes the unbounded wire length as destination size, causing a full stack overflow; other handlers suffer single-byte off-by-one NUL writes. The fix us...

CVE-2026-72210

A flaw was found in the Linux kernel's NTFS filesystem driver. An error in how the driver checks the boundaries of data it processes, specifically an 'off-by-one' error, allows it to read one byte beyond its intended memory region. This 'out-of-bounds read' could potentially lead to the disclosur...
