This advisory addresses nine distinct vulnerabilities in the Linux kernel as packaged by Red Hat Enterprise Linux 8. The issues include CVE-2024-46695 which prevents bypassing permission checks in the inode_setsecctx hook for SELinux and Smack, CVE-2024-49949 which avoids a potential underflow in qdisc_pkt_len_init() with UFO, and CVE-2024-50082 which fixes a crash caused by a race condition between rq_qos_wait and rq_qos_wake_function. Additional fixes include removal of broken LDR (literal) uprobe support on arm64 (CVE-2024-50099), kernel info leak fixes in xfrm algo dumping (CVE-2024-50110), validation of new security association prefix length (CVE-2024-50142), prevention of VMOVP on a dying VPE in irqchip/gic-v4 (CVE-2024-50192), fixing a potential crash in nf_send_reset6() in netfilter (CVE-2024-50256), and initialization of a dangling pointer in vsock/virtio (CVE-2024-50264). The advisory rates the overall impact as moderate and recommends applying the update and rebooting affected systems.

The vulnerabilities collectively could lead to permission bypass, system crashes, information leaks, and potential denial of service conditions in affected Red Hat Enterprise Linux 8 systems. The issues affect core kernel functionality including security modules (SELinux/Smack), networking, block request quality of service, ARM64 probes, and virtual socket communication. Exploitation could impact system stability and security enforcement.

Red Hat has released an official kernel update addressing these vulnerabilities. Users of Red Hat Enterprise Linux 8 and related products should apply the update as detailed in the Red Hat advisory RHSA-2024:10943. A system reboot is required to complete the remediation. No additional mitigations are indicated beyond applying the official patch.
