UBUNTU-CVE-2026-17523

A flaw was found in the Linux kernel in net/can/bcm.c in can: bcm, where an unprivileged local user can exploit this vulnerability to execute arbitrary code within the kernel, which leads to a local privilege escalation LPE. This allows the attacker to gain root privileges and take full control o...

CVE-2026-64331

A flaw was found in the Linux kernel's usbip virtual USB device controller vudc. This vulnerability, a NULL pointer dereference, occurs when vepallocrequest fails to initialize a vrequest's udc field, causing asynchronous input/output AIO cancellations on the FunctionFS path to arrive without a...

CVE-2026-64269

A flaw was found in the Linux kernel's RDMA Remote Direct Memory Access rtrs-srv module. A remote attacker can exploit this vulnerability by sending a crafted RDMA-Write length during an RTRS READ operation that exceeds the intended buffer size. This out-of-bounds read can lead to information...

CVE-2026-64451

A flaw was found in the Linux kernel's tracing subsystem. A local user, by manipulating function tracer options, can trigger a NULL pointer dereference in the funcsetflag function. This vulnerability occurs when the active tracer is switched away from the function tracer while a process has an...

CVE-2026-64309

A flaw was found in the Linux kernel's crypto: ccp module. This vulnerability arises from improper initialization of Secure Nested Paging SNP when handling the ioctlSNPCOMMIT command. A local userspace process can exploit this by sending specific commands via /dev/sev ioctls. If Secure Encrypted...

CVE-2026-64477

A flaw was found in the Linux kernel. When a CPU is taken offline on systems with Sub-NUMA Clustering SNC enabled, a programming error in the resource control resctrl file system can lead to an out-of-bounds memory access. This issue may cause system instability or crashes. The vulnerability aris...

CVE-2026-64363

A flaw was found in the appleir Human Interface Device HID driver in the Linux kernel. A use-after-free UAF vulnerability can occur if a key is pressed shortly before an Apple infrared IR device is disconnected. This timing issue allows a pending timer to access freed memory, which may lead to...

CVE-2026-64456

A flaw was found in the Linux kernel's virtio-rng driver. A malicious or buggy virtualized hardware random number generator virtio-rng backend can report an overly large data length to the guest operating system. This unchecked length can lead to an out-of-bounds read, causing the driver to acces...

CVE-2026-64452

A flaw was found in the Linux kernel's 6LoWPAN IPv6 over Low-Power Wireless Personal Area Networks component. A race condition in the lowpannhcdouncompression function can lead to a use-after-free vulnerability. This occurs when an NHC Next Header Compression descriptor is deallocated while anoth...
