Summary

Moderate: kernel-rt security and bug fix update

Details

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * information leak in scsi_ioctl() (CVE-2022-0494) * use-after-free in tc_new_tfilter() in net/sched/cls_api.c (CVE-2022-1055) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Bug Fix(es): * update RT source tree to the latest AlmaLinux-9.0.z2 Batch (BZ#2105450)

CVE-2022-1055 (GCVE-0-2022-1055)

Vulnerability from cvelistv5 – Published: 2022-03-29 15:05 – Updated: 2024-08-02 23:47

Title

Use after Free in tc_new_tfilter allowing for privilege escalation in Linux Kernel

Summary

A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5

Severity ?

8.6 (High)
