Red Hat Security Advisory: kernel security, bug fix, and enhancement update
kernel: kernel pointer leak due to WARN_ON statement in video driver leads to local information disclosure kernel: use after free due to race condition in the video driver leads to local privilege escalation kernel: null pointer dereference in dlpar_parse_cc_property in arch/powerrc/platforms/pseries/dlpar.c causing denial of service kernel: use-after-free in drivers/bluetooth/hci_ldisc.c kernel: out-of-bounds access in function hclge_tm_schd_mode_vnet_base_cfg kernel: null-pointer dereference in drivers/net/fjes/fjes_main.c kernel: null pointer dereference in drivers/scsi/qla2xxx/qla_os.c kernel: memory leak in ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c kernel: memory leak in  af9005_identify_state() function in drivers/media/usb/dvb-usb/af9005.c kernel: Denial Of Service in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c kernel: A memory leak in the mwifiex_pcie_alloc_cmdrsp_buf() function in drivers/net/wireless/marvell/mwifiex/pcie.c allows to cause DoS kernel: memory leak in the crypto_report() function in crypto/crypto_user_base.c allows for DoS kernel: Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c allow for a DoS kernel: A memory leak in the rtl8xxxu_submit_int_urb() function in drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c allows for a DoS kernel: A memory leak in the predicate_parse() function in kernel/trace/trace_events_filter.c allows for a DoS kernel: out-of-bounds write in ext4_xattr_set_entry in fs/ext4/xattr.c Kernel: kvm: OOB memory write via kvm_dev_ioctl_get_cpuid kernel: mounting a crafted ext4 filesystem image, performing some operations, and unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c kernel: a malicious USB device in the drivers/input/ff-memless.c leads to use-after-free kernel: information leak bug caused  by a malicious USB device in the drivers/media/usb/ttusb-dec/ttusb_dec.c kernel: race condition caused by a malicious USB device in the USB character device driver layer kernel: use-after-free in serial_ir_init_module() in drivers/media/rc/serial_ir.c kernel: cached use of fpu_fpregs_owner_ctx in arch/x86/include/asm/fpu/internal.h can lead to DoS kernel: use-after-free in __ext4_expand_extra_isize and ext4_xattr_set_entry related to fs/ext4/inode.c and fs/ext4/super.c kernel: use-after-free in debugfs_remove in fs/debugfs/inode.c kernel: Null pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c kernel: out-of-bounds write via crafted keycode table kernel: af_packet: TPACKET_V3: invalid timer timeout on error kernel: possible use-after-free due to a race condition in cdev_get of char_dev.c kernel: bad kfree in auditfilter.c may lead to escalation of privilege kernel: out-of-bounds read in in vc_do_resize function in drivers/tty/vt/vt.c kernel: use-after-free in n_tty_receive_buf_common function in drivers/tty/n_tty.c kernel: invalid read location in vgacon_invert_region function in drivers/video/console/vgacon.c kernel: uninitialized kernel data leak in userspace coredumps kernel: SELinux netlink permission check bypass kernel: kernel stack information leak on s390/s390x kernel: possibility of memory disclosure when reading the file /proc/sys/kernel/rh_features kernel: vhost-net: stack overflow in get_raw_socket while checking sk_family field kernel: out-of-bounds write in mpol_parse_str function in mm/mempolicy.c kernel: mishandles invalid descriptors in drivers/media/usb/gspca/xirlink_cit.c kernel: buffer overflow in mt76_add_fragment function in drivers/net/wireless/mediatek/mt76/dma.c kernel: sync of excessive duration via an XFS v5 image with crafted metadata kernel: xdp_umem_reg in net/xdp/xdp_umem.c has an out-of-bounds write which could result in crash and data coruption kernel: sg_write function lacks an sg_remove_request call in a certain failure case kernel: possible to send arbitrary signals to a privileged (suidroot) parent process kernel: referencing inode of removed superblock in get_futex_key() causes UAF kernel: soft-lockups in iov_iter_copy_from_user_atomic() could result in DoS kernel: use-after-free in route4_change() in net/sched/cls_route.c
