CVE-2026-99055

A flaw was found in the Linux kernel's TCP networking subsystem. When handling zero-copy data reception involving certain device memory buffers, the kernel fails to properly validate memory fragment types before dereferencing them, resulting in a null pointer dereference. An attacker sending...

CVE-2026-98299

A flaw was found in the Linux kernel's TCP networking subsystem. A privileged local user can cause a Denial of Service DoS by configuring TCP receive buffer limits to an abnormally low value. This improper setting causes the kernel to encounter a division-by-zero error during buffer adjustment...
