CVE-2023-1872 (GCVE-0-2023-1872)

Vulnerability from cvelistv5 – Published: 2023-04-12 15:40 – Updated: 2025-02-13 16:39

Title

Use-after-free in Linux kernel's io_uring subsystem

Summary

A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local privilege escalation. The io_file_get_fixed function lacks the presence of ctx->uring_lock which can lead to a Use-After-Free vulnerability due a race condition with fixed files getting unregistered. We recommend upgrading past commit da24142b1ef9fd5d36b76e36bab328a5b27523e8.

Severity

7.8 (High)

CVE-2023-23454 (GCVE-0-2023-23454)

Vulnerability from cvelistv5 – Published: 2023-01-12 00:00 – Updated: 2025-03-20 20:55

Summary

cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).

Severity

5.5 (Medium)
