CVE-2026-63837

A flaw was found in the Linux kernel's Elastic Network Adapter ENA driver. The driver's Precision Time Protocol PTP Hardware Clock PHC support, specifically the enaphcgettimex64 function, fails to check the return code of an internal timestamp retrieval function. This oversight can lead to...

CVE-2026-63837

The CVE affects the Linux kernel ENA PHC path. In ena_phc_gettimex64, the output timestamp was written to the user via the PTP ioctl regardless of whether ena_com_phc_get_timestamp() succeeded. If an error occurs (e.g., PHC disabled or blocked), the timestamp could contain uninitialized memory or...

CVE-2026-54466

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.7.5, the frame format in draft versions of the WebSocket protocol includes a length header that allows an arbitrarily large integer to be encoded as a sequence of bytes with the high bit set. By sending an indefinite...

CVE-2026-54466

The CVE-2026-54466 entry concerns websocket-driver (WebSocket protocol handler). Prior to version 0.7.5, draft75.js parses a length header that can be abused by sending a sequence of bytes (0x80 or higher), causing an ever-growing integer to be produced. Because JavaScript numbers are 64‑bit floa...

CVE-2026-52971

A flaw was found in the Linux kernel's Elastic Network Adapter ENA driver, specifically within the Precision Time Protocol Hardware Clock PHC timestamp retrieval function. A race condition exists where the gettimestamp function could attempt to access memory that has already been freed by the...

CVE-2026-53222

In the Linux kernel, CVE-2026-53222 relates to the ptp: ocp driver. The root cause was use-after-free during driver removal caused by freeing resources in ptp_ocp_detach() before ptp_clock_unregister(), after a change that disables events via ptp_disable_all_events(). The fix changes the free/unr...
