FortiClient Vulnerability

Security Vulnerabilities fixed in kernel-rt RHSA-2021:0857

Description

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): kernel: Local buffer overflow in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c (CVE-2020-25211) kernel: SCSI target (LIO) write to any block on ILO backstore (CVE-2020-28374) kernel: locking issue in drivers/tty/tty_jobctrl.c can lead to an use-after-free (CVE-2020-29661) kernel: malicious USB devices can lead to multiple out-of-bounds write (CVE-2019-19532) kernel: out-of-bounds reads in pinctrl subsystem.
