Ilja Van Sprundel discovered that the SCTP implementation in the Linux kernel did not properly perform size validations on incoming packets in some situations. An attacker could possibly use this to expose sensitive information kernel memory. CVE-2021-3655 It was discovered that the AMD...

kernel: protection for sequences of pointer arithmetic operations against speculatively out-of-bounds loads can be bypassed to leak content of kernel memory

A vulnerability was discovered in retrieveptrlimit in kernel/bpf/verifier.c in the Linux kernel mechanism to mitigate speculatively out-of-bounds loads Spectre mitigation. In this flaw a local, special user privileged CAPSYSADMIN BPF program running on affected systems may bypass the protection,...

ASB-A-184622099

In qrtrrecvmsg of qrtr.c, there is a possible leak of kernel memory due to uninitialized data. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation...

CVE-2021-25457: Improper Input Validation

An improper input validation vulnerability in DSP driver prior to SMR Sep-2021 Release 1 allows local attackers to get a limited kernel memory information...

CVE-2021-21781

An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66 and v5.4.54. The latest version 5.11-rc4 seems to still be vulnerable. A userland application can read the contents of the sigpage, which can leak kernel memory contents. An attacker can read a...

Huawei HarmonyOS Denial of Service Vulnerability (CNVD-2021-60511)

Huawei HarmonyOS is an operating system from Huawei China. It provides a microkernel-based distributed operating system. Huawei HarmonyOS suffers from a denial-of-service vulnerability that can be exploited by local attackers to cause a kernel memory leak...

DEBIAN-CVE-2021-34556

In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack...

CVE-2021-35477

In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled...
