The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * Kernel: vhost_net: infinite loop while receiving packets leads to DoS * Kernel: page cache side channel attacks * kernel: Buffer overflow in hidp_process_report * kernel: l2tp: Race condition between pppol2tp_session_create and l2tp_eth_create * kernel: kvm: guest userspace to guest kernel write * 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: 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: 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 * 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: HID: debug: Buffer overflow in hid_debug_events_read in drivers/hid/hid-debug.c * 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: Information leak in cdrom_ioctl_drive_status * kernel: out-of-bound read in memcpy_fromiovecend * Kernel: KVM: leak of uninitialized stack contents to guest For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
