gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service...

Solara <1.35.1 - Local File Inclusion

A Local File Inclusion LFI vulnerability was identified in widgetti/solara, in version 1.35.1, which was fixed in version 1.35.1. This vulnerability arises from the application's failure to properly validate URI fragments for directory traversal sequences such as '../' when serving static files. ...

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...

CVE-2026-53109

A flaw was found in the Linux kernel's powerpc page table fragment handling. During process exit, a race condition can occur where a page table fragment's active flag is not properly cleared. This can lead to a "bad page state" error, potentially causing system instability or a Denial of Service...

CVE-2026-13351

Zephyr's IPv6 network stack can be prevented from receiving or processing future incoming packets by sending a small number of maliciously fragmented IPv6 packets. When such a packet is handled by the fragment-header processing path, the associated RX network packet buffer allocated from a memory...

CVE-2026-53175

The CVE-2026-53175 entries describe a use-after-free in the Linux kernel’s fragment reassembly during netns teardown. Root cause: fqdir_pre_exit() flushes fragment queues but may leave freed skbs referenced by fragment queue state (fragments_tail/last_run_head) before INET_FRAG_COMPLETE is set, a...

CVE-2026-53175 inet: frags: fix use-after-free caused by the fqdir_pre_exit() flush

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...

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-2026-52916

In the Linux kernel, the following vulnerability has been resolved: batman-adv: frag: disallow unicast fragment in fragment batadvfragskbbuffer is called by batadvbatmanskbrecv when a BATADVUNICASTFRAG packet is received. Once all fragments are collected and the packet is reassembled,...

CVE-2026-48779

A flaw was found in ws, an open source WebSocket client and server. A remote attacker can exploit this memory exhaustion vulnerability by sending a high volume of exceptionally small fragments and data chunks. This action forces the affected component to allocate and hold structural wrappers that...

USN-8462-1: Linux kernel (Oracle) vulnerabilities

It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-31431 It was discovered that the Linux kernel did n...

Astra Linux – Vulnerabilities in Linux, Linux-5.15, Linux-5.10, Linux-6.1

In the Linux kernel, the following vulnerabilities have been resolved: rxrpc: DATA/RESPONSE packets are also unshared when paged fragments are present. The DATA-packet handler in rxrpcinputcallevent and the RESPONSE handler in rxrpcverifyresponse copy the skb into a linear sequence before calling...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

Transmitted requests in Xen’s virtual network protocol can consist of multiple parts. Although none of them are actually useful, except for the initial part, any of these parts can be of zero length, meaning they carry no data at all. Apart from the certain initial portion of the data to be...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: fixed a use-after-free in r535gsprpcpush. The RPC container is released after being passed to r535gsprpcsend. When sending the initial fragment of a large RPC and passing the caller’s RPC container, the container wil...
