In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - fix heap-buffer-overflow in imspcuprocessdata The imspcuprocessdata processes incoming URB data byte by byte. However, it fails to check if the readpos index exceeds IMSPCUBUFSIZE. If a malicious USB device sends...

CVE-2026-64565

CVE-2026-64565 (Linux kernel, ims-pcu driver) fixes a heap-buffer-overflow in ims_pcu_process_data(). The bug: input data processed byte-by-byte without checking read_pos against IMS_PCU_BUF_SIZE, allowing a larger-than-expected USB packet to increment read_pos and, via proximity to read_buf, ove...

CVE-2026-56444

A Denial of Service DoS flaw exists in Unbound under specific serve-expired and discard-timeout configurations. By sending crafted queries, a remote attacker can exhaust an internal counter, causing the server to drop new legitimate client queries and degrade resolution services. Mitigation To...

EUVD-2026-49881

tiny-http through 0.12.0 contains an HTTP request smuggling vulnerability that allows remote attackers to desynchronize request framing by sending a Transfer-Encoding header with any value, including non-chunked codings, which causes the library to unconditionally apply chunk-decoding and discard...

SUSE CVE-2026-56444

In NLnet Labs Unbound 1.20.0 up to and including 1.25.1, when Unbound is configured with 'serve-expired: yes' and 'serve-expired-client-timeout discard-timeout 0' contrary to the suggested values, the discard-timeout branch during the serve expired logic drops an aged client reply without...

webtransport-go: Memory Exhaustion Attack due to Buffering of Unknown Capsules

Summary An attacker can cause excessive memory allocation in webtransport-go by sending an unknown WebTransport capsule with a large payload. The implementation skips unknown capsules by reading the entire capsule body into memory, instead of draining it without retaining the data. This can lead ...
