CVE-2023-0458 (GCVE-0-2023-0458)

Vulnerability from cvelistv5 – Published: 2023-04-26 18:03 – Updated: 2025-02-13 16:38

Title

Spectre V1 Gadget in do_prlimit in the Linux Kernel

Summary

A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents. We recommend upgrading past version 6.1.8 or commit 739790605705ddcf18f21782b9c99ad7d53a8c11

CVE-2023-3090 (GCVE-0-2023-3090)

Vulnerability from cvelistv5 – Published: 2023-06-28 19:06 – Updated: 2025-03-05 18:55

Title

Out-of-bounds write in Linux kernel's ipvlan network driver

Summary

A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e.

Severity ?

7.8 (High)

CVE-2023-1998 (GCVE-0-2023-1998)

Vulnerability from cvelistv5 – Published: 2023-04-21 14:51 – Updated: 2025-02-13 16:39

Title

Spectre v2 SMT mitigations problem in Linux kernel

Summary

The Linux kernel allows userspace processes to enable mitigations by calling prctl with PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection. However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons, which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target injection against which STIBP protects.
