title: Red Hat Security Advisory: kernel-rt security and bug fix update
description: kernel: Information exposure in fd_locked_ioctl function in drivers/block/floppy.c kernel: Memory leak in drivers/net/wireless/mac80211_hwsim.c:hwsim_new_radio_nl() can lead to potential denial of service kernel: Buffer overflow in hidp_process_report kernel: HID: debug: Buffer overflow in hid_debug_events_read() in drivers/hid/hid-debug.c kernel: l2tp: Race condition between pppol2tp_session_create() and l2tp_eth_create() kernel: kvm: guest userspace to guest kernel write kernel: Integer overflow in the alarm_timer_nsleep function kernel: NULL pointer dereference in lookup_slow function kernel: NULL pointer dereference in xfs_da_shrink_inode function kernel: NULL pointer dereference in fs/xfs/libxfs/xfs_inode_buf.c kernel: use-after-free Read in vhost_transport_send_pkt kernel: use-after-free in ucma_leave_multicast in drivers/infiniband/core/ucma.c kernel: Mishandling of indirect calls weakens Spectre mitigation for paravirtual guests kernel: Information leak in cdrom_ioctl_drive_status kernel: out-of-bound read in memcpy_fromiovecend() kernel: TLB flush happens too late on mremap kernel: Heap address information leak while using L2CAP_GET_CONF_OPT kernel: Heap address information leak while using L2CAP_PARSE_CONF_RSP kernel: denial of service vector through vfio DMA mappings Kernel: vhost_net: infinite loop while receiving packets leads to DoS Kernel: page cache side channel attacks Kernel: KVM: leak of uninitialized stack contents to guest kernel: OOB write due to missing bounds check leads to local privilege escalation kernel: overlayfs: NULL pointer dereference in ovl_posix_acl_create function in fs/overlayfs/dir.c kernel: fix race condition between mmget_not_zero()/get_task_mm() and core dumping kernel: a NULL pointer dereference in drivers/scsi/megaraid/megaraid_sas_base.c leading to DoS kernel: fs/ext4/extents.c leads to information disclosure
