CVE-2026-45998

A flaw was found in the Linux kernel's rxrpc subsystem. This vulnerability arises when the system attempts to unshare a packet buffer, and the operation fails due to an allocation issue. This failure can lead to a Use-After-Free UAF condition, where the system attempts to access memory that has...

CVE-2026-46000

A flaw was found in the Linux kernel's rxrpc component. Security operations that decrypt RESPONSE packets in place may share the socket buffer skbuff with a packet sniffer. This could allow a local attacker or an attacker with network access to intercept and view decrypted portions of these...

CVE-2026-46031

A flaw was found in the Linux kernel's ks8851 network driver. Under specific conditions related to network packet processing and interrupt handling, a race condition can occur. This vulnerability can lead to a system deadlock, causing the affected system to become unresponsive or crash...

CVE-2026-46038

A flaw was found in the Linux kernel's qrtr nameserver component. When a node sends a BYE packet, the nameserver fails to free the associated node memory, leading to a memory leak. This vulnerability can result in resource exhaustion over time, potentially impacting system stability and...

In GnuPG before 2.5.17, a long signature packet length causes parsesignature to return success with sig-data set to a NULL value, leading to a denial of service application crash...

CVE-2026-46085

A flaw was found in the Linux kernel's rxrpc subsystem, specifically in the rxkad crypto unalignment handling. A remote attacker could send a specially crafted packet with a misaligned crypto length. This improper handling could lead to system instability or a denial of service DoS due to incorre...

CVE-2026-44315

free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's NEF mounts the 3gpp-pfd-management API without inbound OAuth2/bearer-token authorization. A network attacker who can reach NEF on the SBI can create, read, and delete PFD-management transaction state with a...

EUVD-2026-32251

In the Linux kernel, the following vulnerability has been resolved: bpf: Return proper address for non-zero offsets in insn array The mapdirectvalueaddr function of the instruction array map incorrectly adds offset to the resulting address. This is a bug, because later the resolvepseudoldimm64...

In the Linux kernel, the following vulnerability has been resolved: bpf: Preserve id of register in synclinkedregs synclinkedregs copies the id of knownreg to reg when propagating bounds of knownreg to reg using the off of knownreg, but when knownreg was linked to reg like: knownreg = reg ; both...

EUVD-2026-32216

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix tcx/netkit detach permissions when prog fd isn't given This commit fixes a security issue where BPFPROGDETACH on tcx or netkit devices could be executed by any user when no program fd was provided, bypassing permission...

CVE-2026-44838

RabbitMQ is a messaging and streaming broker. From 4.2.0 to before 4.2.4, RabbitMQ's MQTT plugin allows for topic-level authorization using regular expressions with variable substitution. Administrators can create patterns such as ^clientid-sensors$ to restrict user access to topics that include...

CVE-2026-46038

In the Linux kernel, the following vulnerability has been resolved: net: qrtr: ns: Free the node during ctrlcmdbye A node sends the BYE packet when it is about to go down. So the nameserver should advertise the removal of the node to all remote and local observers and free the node finally. But...

CVE-2026-46000

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix conn-level packet handling to unshare RESPONSE packets The security operations that verify the RESPONSE packets decrypt bits of it in place - however, the skbuff may be shared with a packet sniffer, which would lead to...

CVE-2026-45998

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix potential UAF after skbunshare failure If skbunshare fails to unshare a packet due to allocation failure in rxrpcinputpacket, the skb pointer in the parent rxrpciothread will be NULL'd out. This will likely cause the...

In the Linux kernel, the following vulnerability has been resolved: bpf: Preserve id of register in synclinkedregs synclinkedregs copies the id of knownreg to reg when propagating bounds of knownreg to reg using the off of knownreg, but when knownreg was linked to reg like: knownreg = reg ; both...

UBUNTU-CVE-2026-45951

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix a potential use-after-free of BTF object Refcounting in the checkpseudobtfid function is incorrect: the checkpseudobtfid function might get called with a zero refcounted btf. Fix this, and patch related code accordingly...

UBUNTU-CVE-2026-45971

In the Linux kernel, the following vulnerability has been resolved: bpf: Limit bpf program signature size Practical BPF signatures are significantly smaller than KMALLOCMAXCACHESIZE Allowing larger sizes opens the door for abuse by passing excessive size values and forcing the kernel into expensi...
