CVE-2026-28525

SWUpdate contains an integer underflow vulnerability in the multipart upload parser in mongoosemultipart.c that allows unauthenticated attackers to cause a denial of service by sending a crafted HTTP POST request to /upload with a malformed multipart boundary and controlled TCP stream timing...

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...

SUSE CVE-2026-31656

In the Linux kernel, the following vulnerability has been resolved: drm/i915/gt: fix refcount underflow in intelengineparkheartbeat A use-after-free / refcount underflow is possible when the heartbeat worker and intelengineparkheartbeat race to release the same engine-heartbeat.systole request. T...

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-2026-31656

A flaw was found in the Linux kernel's i915 graphics driver. A race condition exists between the heartbeat worker and intelengineparkheartbeat functions when releasing an engine request. This can lead to a reference count refcount underflow, resulting in a use-after-free vulnerability. A local...

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...

CVE-2026-33662

OP-TEE (Trusted Execution Environment) has a concrete vulnerability in RSASSA PKCS#1 v1.5 padding. Affected versions are 3.8.0–4.10; the padding size (PS) is computed as modulus size minus digest/EMSA fields in emsa_pkcs1_v1_5_encode() (rsassa.c). If the modulus is small enough, this subtraction ...
