gnutls: GnuTLS: Denial of Service via heap buffer overflow in DTLS handshake fragment reassembly

A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in mergehandshakepacket where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the messagelength field remains...

EUVD-2026-39266

In the Linux kernel, the following vulnerability has been resolved: inet: frags: fix use-after-free caused by the fqdirpreexit flush On netns teardown, fqdirpreexit walks the fqdir rhashtable and flushes every fragment queue that is not yet complete using inetfragqueueflush. That helper frees all...

SUSE CVE-2026-52914

In the Linux kernel, the following vulnerability has been resolved: batman-adv: fix fragment reassembly length accounting batman-adv keeps a running payload length for queued fragments and uses it to validate a fragment chain before reassembly. That accounting currently allows the accumulated...

CVE-2026-52914

A flaw was found in the Linux kernel's batman-adv component. This vulnerability allows a local attacker to cause a denial of service DoS by sending malformed fragment chains. The flaw is due to incorrect accounting of fragment reassembly length, which can be truncated during updates, bypassing...

CVE-2026-52914

In the Linux kernel, the batman-adv component is affected by CVE-2026-52914. The root cause is an accounting bug where the accumulated fragment length used for validating queued fragment chains can be truncated during updates. This allows malformed fragment chains to bypass validation and drive r...
