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: use after free due to race condition in the video driver leads to local privilege escalation (CVE-2019-9458)

  • kernel: use-after-free in drivers/bluetooth/hci_ldisc.c (CVE-2019-15917)

  • kernel: out-of-bounds access in function hclge_tm_schd_mode_vnet_base_cfg (CVE-2019-15925)

  • kernel: memory leak in ccp_run_sha_cmd() (CVE-2019-18808)

  • kernel: Denial Of Service in the __ipmi_bmc_register() (CVE-2019-19046)

  • kernel: out-of-bounds write in ext4_xattr_set_entry in fs/ext4/xattr.c (CVE-2019-19319)

  • Kernel: kvm: OOB memory write via kvm_dev_ioctl_get_cpuid (CVE-2019-19332)

  • kernel: use-after-free in ext4_put_super (CVE-2019-19447)

  • kernel: a malicious USB device in the drivers/input/ff-memless.c leads to use-after-free (CVE-2019-19524)

  • kernel: race condition caused by a malicious USB device in the USB character device driver layer (CVE-2019-19537)

  • kernel: use-after-free in serial_ir_init_module() (CVE-2019-19543)

  • kernel: use-after-free in __ext4_expand_extra_isize and ext4_xattr_set_entry (CVE-2019-19767)

  • kernel: use-after-free in debugfs_remove (CVE-2019-19770)

  • kernel: out-of-bounds write via crafted keycode table (CVE-2019-20636)

  • kernel: possible use-after-free due to a race condition in cdev_get of char_dev.c (CVE-2020-0305)

  • kernel: out-of-bounds read in in vc_do_resize (CVE-2020-8647)

  • kernel: use-after-free in n_tty_receive_buf_common (CVE-2020-8648)

  • kernel: invalid read location in vgacon_invert_region (CVE-2020-8649)

  • kernel: uninitialized kernel data leak in userspace coredumps (CVE-2020-10732)

  • kernel: SELinux netlink permission check bypass (CVE-2020-10751)

  • kernel: out-of-bounds write in mpol_parse_str function in mm/mempolicy.c (CVE-2020-11565)

  • kernel: out-of-bounds write in xdp_umem_reg (CVE-2020-12659)

  • kernel: sg_write function lacks an sg_remove_request call in a certain failure case (CVE-2020-12770)

  • kernel: possible to send arbitrary signals to a privileged (suidroot) parent process (CVE-2020-12826)

  • kernel: referencing inode of removed superblock in get_futex_key() causes UAF (CVE-2020-14381)

  • kernel: soft-lockups in iov_iter_copy_from_user_atomic() could result in DoS (CVE-2020-25641)

  • kernel: kernel pointer leak due to WARN_ON statement in video driver leads to local information disclosure (CVE-2019-9455)

  • kernel: null-pointer dereference in drivers/net/fjes/fjes_main.c (CVE-2019-16231)

  • kernel: Two memory leaks in the rtl_usb_probe() (CVE-2019-19063)

  • kernel: A memory leak in the rtl8xxxu_submit_int_urb() (CVE-2019-19068)

  • kernel: A memory leak in the predicate_parse() function in kernel/trace/trace_events_filter.c allows for a DoS (CVE-2019-19072)

  • kernel: information leak bug caused by a malicious USB device in the drivers/media/usb/ttusb-dec/ttusb_dec.c (CVE-2019-19533)

  • kernel: Null pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c (CVE-2019-20054)

  • kernel: possibility of memory disclosure when reading the file /proc/sys/kernel/rh_features (CVE-2020-10774)
