CVE-2026-46323

In the Linux kernel, the following vulnerability has been resolved: net: gro: don't merge zcopy skbs skbgroreceive can currently copy frags between the source and GRO skb, without checking the zerocopy status, and in particular the SKBFLMANAGEDFRAGREFS flag. When SKBFLMANAGEDFRAGREFS is set, the...

cryptography: Cryptography: Buffer overflow via non-contiguous buffer in API

A flaw was found in the cryptography library. This vulnerability occurs when a non-contiguous buffer is passed to certain application programming interfaces APIs that accept Python buffers, such as Hash.update. A remote attacker could exploit this to cause a buffer overflow, potentially leading t...

Denial Of Service (DoS)

Netty is vulnerable to Denial of Service DoS. The vulnerability is due to unbounded accumulation of incomplete SCTP message fragments in nested CompositeByteBuf structures without limits on fragment count, size, or stream identifiers, which allows an attacker to exhaust memory and processing...

In the Linux kernel, the following vulnerability has been resolved: spi: topcliff-pch: fix use-after-free on unbind Give the driver a chance to flush its queue before releasing the DMA buffers on driver unbind...

FreeBSD Security Advisory - FreeBSD-SA-26:26.ktls

FreeBSD Security Advisory - The KTLS receive path decrypted each record in place, assuming that the mbufs holding received data were anonymous and safe to modify. This assumption does not hold for data placed on a socket by sendfile2, which can reference file-backed memory directly through...

PT-2026-47818

Name of the Vulnerable Software and Affected Versions NETGEAR affected versions not specified Description A buffer overflow occurs due to insufficient input validation of buffers. This allows authenticated administrators connected to the local network to make unauthorized modifications to the...

Netty: SCTP reassembly nests buffers without bound

For each non-complete SctpMessage fragment the handler does fragments.putstreamId, Unpooled.wrappedBufferfrag, byteBuf, wrapping the previous accumulator and the new slice into a new CompositeByteBuf every time. After N fragments the accumulator is an N-deep chain of composites, each holding...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to unbounded nesting of composite buffers in the SCTP message reassembly process. An attacker can exhaust system memory and cause a denial of service by sending a large number of...

CVE-2026-46301

CVE-2026-46301 affects the Linux kernel SPI driver for topcliff-pch. The issue is a use-after-free on unbind caused by not flushing the driver queue before freeing DMA buffers. A patch fixes this by ensuring the queue is flushed prior to DMA buffer release. The NVD entry lists a High impact (CVSS...

libssh: Incorrect Return Code Handling in ssh_kdf() in libssh

A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the sshkdf function responsible for key derivation. Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success—the function may mistakenl...
