RHSA-2022:0622: Important: kernel-rt security and bug fix update

First published: Tue Feb 22 2022(Updated: )

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.<br>Security Fix(es):<br><li> kernel: use after free in eventpoll.c may lead to escalation of privilege (CVE-2020-0466)</li> <li> kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)</li> <li> kernel: xfs: raw block device data leak in XFS_IOC_ALLOCSP IOCTL (CVE-2021-4155)</li> <li> kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)</li> <li> kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)</li> <li> kernel: out of bounds write in hid-multitouch.c may lead to escalation of privilege (CVE-2020-0465)</li> <li> kernel: double free in bluetooth subsystem when the HCI device initialization fails (CVE-2021-3564)</li> <li> kernel: use-after-free in function hci_sock_bound_ioctl() (CVE-2021-3573)</li> <li> kernel: possible use-after-free in bluetooth module (CVE-2021-3752)</li> 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.<br>Bug Fix(es):<br><li> kernel-rt: update to the latest RHEL7.9.z12 source tree (BZ#2039101)</li>
