DEBIAN-CVE-2024-36348
A transient execution vulnerability in some AMD processors may allow a user process to infer the control registers speculatively even if UMIP feature is enabled, potentially resulting in information leakage...
kernel: dm ioctl: prevent potential spectre v1 gadget
A vulnerability was found in the Linux kernel's dm-ioctl interface in the lookupioctl function, which accepts a user-provided cmd value that is used to index the ioctls array directly. This issue could lead to an out-of-bounds access if the CPU speculatively executes the array access before cmd i...
microcode_ctl: From CVEorg collector
New Spectre-v2 attack classes have been discovered within CPU architectures that enable self-training exploitation of speculative execution within the same privilege domain. These novel techniques bypass existing hardware and software mitigations, including IBPB, eIBRS, and BHINO, by leveraging...

ABB M2M Gateway Information Disclosure in embedded Linux Kernel for some AMD CPUs (CVE-2023-20569)
A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure. This plugin only works with Tenable.ot. Please visit...

kernel: protect the fetch of ->fd[fd] in do_dup2() from mispredictions
In the Linux kernel, the following vulnerability has been resolved: protect the fetch of -fdfd in dodup2 from mispredictions both callers have verified that fd is not greater than -maxfds; however, misprediction might end up with tofree = fdt-fdfd; being speculatively executed. That's wrong for t...
Kudzu: Fast and Simple High-Throughput BFT
We present Kudzu, a high-throughput atomic broadcast protocol with an integrated fast path. Our contribution is based on the combination of two lines of work. Firstly, our protocol achieves finality in just two rounds of communication if all but $p$ out of $n = 3f + 2p + 1$ participating replicas...
