kernel: Linux kernel: Memory leak in RDMA/irdma subsystem leads to Denial of Service

A flaw was found in the Linux kernel's RDMA/irdma subsystem. When the irdma module is unloaded, certain memory objects PBLEs are not properly released, leading to a memory leak. A local attacker could repeatedly trigger this condition, causing system memory to be exhausted and resulting in a Deni...

kernel: RDMA/rxe: Fix "kernel NULL pointer dereference" error

A NULL pointer dereference vulnerability was found in the RXE Soft-RoCE RDMA driver in the Linux kernel. When rxequeueinit fails during queue pair initialization in rxeqpinitreq, the task function and argument pointers qp-req.task.func and qp-req.task.arg remain uninitialized. The cleanup functio...

A flaw was found in an error-handling function in the Linux kernel's NVMe driver. This flaw allows an attacker with control over NVMe links to cause a denial of service...

Another Side Channel in Intel Chips

Not that serious, but interesting: In late 2011, Intel introduced a performance enhancement to its line of server processors that allowed network cards and other peripherals to connect directly to a CPU's last-level cache, rather than following the standard and significantly longer path through t...

Intel CPUs Vulnerable to Sensitive Data Leakage in NetCAT Attack

Researchers have identified a new side-channel attack impacting all modern Intel server processors made since 2012. The vulnerability could allow bad actors to sniff out encrypted passwords as they are being typed into a secure shell session SSH; but, luckily, such an attack would be difficult to...

New Rowhammer Attack Can Hijack Computers Remotely Over the Network

Exploitation of Rowhammer attack just got easier. Dubbed 'Throwhammer,' the newly discovered technique could allow attackers to launch Rowhammer attack on the targeted systems just by sending specially crafted packets to the vulnerable network cards over the local area network. Known since 2012,...
