xorg: xwayland: X.Org X server: Denial of Service via integer underflow in XKB compatibility map handling

A flaw was found in the X.Org X server. This integer underflow vulnerability, specifically in the XKB compatibility map handling, allows an attacker with local or remote X11 server access to trigger a buffer read overrun. This can lead to memory-safety violations and potentially a denial of servi...

SUSE CVE-2026-31649

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix integer underflow in chain mode The jumbofrm chain-mode implementation unconditionally computes len = nopagedlen - bmax; where nopagedlen = skbheadlenskb linear bytes only and bmax is BUFSIZE8KiB or BUFSIZE2KiB...

CVE-2026-31662

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC protocol. An attacker can exploit an integer underflow vulnerability by sending duplicate group acknowledgment messages GRPACKMSG. This causes the bcackers counter to wrap around, leading to persistent network...

CVE-2026-31649

A flaw was found in the Linux kernel's stmmac network driver. An integer underflow vulnerability in the jumbofrm function, when processing specially crafted fragmented network packets, can lead to a memory disclosure and potential memory corruption. This issue allows an attacker to read arbitrary...

CVE-2026-31617

A flaw was found in the Linux kernel's USB Network Control Model NCM gadget driver. A malicious USB host could exploit an integer underflow vulnerability when processing Network Transfer Block NTB headers. This allows the host to manipulate internal data pointers, causing adjacent kernel memory t...
