New Linux pedit COW Exploit Enables Root Access by Poisoning Cached Binaries

A flaw in the Linux kernel's traffic-control subsystem can let a local unprivileged user gain root on affected systems. CVE-2026-46331, nicknamed "pedit COW ," is an out-of-bounds write in the packet-editing action actpedit that corrupts shared page-cache memory. A public, working exploit appeare...

CVE-2026-53085

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This use-after-free vulnerability occurs when the taskvma iterator reads task memory without properly acquiring a reference, allowing the memory structure to be freed concurrently while still in use. This can lead to...

New DirtyClone Linux Kernel Flaw Lets Local Users Gain Root via Cloned Packets

DirtyClone is a new Linux kernel privilege escalation in the DirtyFrag family. JFrog Security Research published a working exploit walkthrough for the flaw on June 25, the first public demonstration for this variant. Tracked as CVE-2026-43503 CVSS 8.8, it lets a local user corrupt file-backed...

CVE-2026-53240

A flaw was found in the Linux kernel's xfrm: iptfs component. A race condition during partial packet reassembly in the inputprocesspayload function can lead to a use-after-free vulnerability. This occurs when a concurrent process frees a packet buffer skb before it is checked, allowing subsequent...

UBUNTU-CVE-2026-53275

In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: Fix use-after-free when processing MLD queries When processing an MLD query, a pointer to the multicast group address is retrieved when initially parsing the packet. This pointer is later dereferenced without being...

UBUNTU-CVE-2026-53147

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: Validate XDomain request packet size before type cast tbxdphandlerequest casts the received packet buffer to protocol-specific structs without verifying that the allocation is large enough for the target type. A peer...

UBUNTU-CVE-2026-53223

In the Linux kernel, the following vulnerability has been resolved: net: guard timestamp cmsgs to real error queue skbs skbiserrqueue treats PACKETOUTGOING as the sole marker for an skb from skerrorqueue. That assumption is not true for AFPACKET sockets: outgoing packet taps are also delivered to...

CVE-2026-53184

A flaw was found in the Linux kernel. When a User Datagram Protocol UDP socket is configured with a sockmap, and a BPF Berkeley Packet Filter program attached to it calls a socket-lookup helper, the skb-dev field is not properly cleared. This improper handling of the skb-dev field can lead to a...

CVE-2026-53070

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP over User Datagram Protocol UDP implementation. An issue with managing the transmission context across different processing units could lead to incorrect recursion level detection. This can cause network packets to b...

CVE-2026-53034

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF and sockmap components, specifically within the afunix socket operations. A race condition occurs during the connection process where a socket's state is updated before its peer is fully assigned. This timing issue can lead to a...

CVE-2026-53014

A flaw was found in the Linux kernel. When the kernel's traffic control TC subsystem processes network packets for redirection across different types of network devices, it can incorrectly handle packet headers. This can lead to corruption of network packet data. A local attacker could potentiall...

gnutls: gnutls: Denial of Service via DTLS packet reordering vulnerability

A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security DTLS packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This...

CVE-2026-53033

A flaw was found in the Linux kernel's sockmap functionality. A race condition exists in the unixstreambpfupdateproto function when a BPF Berkeley Packet Filter iterator program updates a sockmap. This can lead to a use-after-free UaF vulnerability, where memory is accessed after it has been free...

CVE-2026-53074

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. Specifically, the bpfprogtestrunskb function, responsible for testing BPF programs with network packets, did not properly validate the length of IPv4 and IPv6 inputs. This could allow the kernel to attempt to access...

CVE-2026-53076

A flaw was found in the Linux kernel. This vulnerability, located in the BPF Berkeley Packet Filter subsystem, involves an out-of-bounds read when data is copied between specific types of BPF maps. The system incorrectly handles data sizes that are not aligned to a specific memory boundary, causi...

CVE-2026-53094

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF component. When a dev-bound-only BPF program undergoes Just-In-Time JIT compilation with constant blinding enabled, a stale pointer to a freed program can occur. This issue arises when the network namespace is destroyed, leading to...

CVE-2026-40012

ECS zero scoped answers are stored in the packet cache while they should not. This impacts only configurations that have ECS enabled;...

CVE-2026-40012 Information about ECS zero scoped answers might leak to clients that use a specific ECS

ECS zero scoped answers are stored in the packet cache while they should not. This impacts only configurations that have ECS enabled;...

CVE-2026-40012

The vulnerability CVE-2026-40012 affects configurations with ECS enabled, where ECS zero-scoped answers are stored in the packet cache instead of being properly restricted, potentially leaking to clients. The issue has a network-based attack surface with low confidentiality impact (CVSS v3.1: 5.3...
