RHSA-2020:1769 Red Hat Security Advisory: kernel security, bug fix, and enhancement update
kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence kernel: triggering AP to send IAPP location updates for stations before the required authentication process has completed can lead to DoS kernel: memory leak in the kernel_read_file function in fs/exec.c allows to cause a denial of service Kernel: net: using kernel space address bits to derive IP ID may potentially break KASLR kernel: use-after-free in function __mdiobus_register() in drivers/net/phy/mdio_bus.c kernel: An out-of-bounds read in drivers/scsi/qedi/qedi_dbg.c leading to crash or information disclosure kernel: a NULL pointer dereference in drivers/net/wireless/ath/ath10k/usb.c leads to a crash kernel: Null pointer dereference in the sound/usb/line6/pcm.c kernel: Null pointer dereference in the sound/usb/line6/driver.c kernel: null pointer dereference in drivers/net/wireless/intel/iwlwifi/pcie/trans.c kernel: buffer-overflow hardening in WiFi beacon validation code. kernel: unprivileged users able to create RAW sockets in AF_IEEE802154 network protocol kernel: unprivileged users able to create RAW sockets in AF_ISDN network protocol kernel: The flow_dissector feature allows device tracking kernel: integer overflow in tcp_ack_update_rtt in net/ipv4/tcp_input.c kernel: dos in mlx5_fpga_conn_create_cq() function in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c kernel: dos in mlx5_fw_fatal_reporter_dump() function in drivers/net/ethernet/mellanox/mlx5/core/health.c kernel: memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c allows DoS kernel: Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/net/wireless/marvell/mwifiex/pcie.c allows for a DoS kernel: A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c allows for a DoS kernel: Multiple memory leaks in the iwl_pcie_ctxt_info_gen3_init() function in drivers/net/wireless/intel/iwlwifi/pcie/ctxt-info-gen3.c allows for a DoS kernel: A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c allows for a DoS kernel: Four memory leaks in the acp_hw_init() function in drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c allow for a DoS kernel: Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel (DOS) kernel: a memory leak in the ath9k management function in allows local DoS kernel: memory leak in bnxt_re_create_srq function in drivers/infiniband/hw/bnxt_re/ib_verbs.c kernel: malicious USB devices can lead to multiple out-of-bounds write kernel: information leak bug caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c kernel: when cpu.cfs_quota_us is used allows attackers to cause a denial of service against non-cpu-bound applications kernel: some ipv6 protocols not encrypted over ipsec tunnel kernel: use-after-free in i915_ppgtt_close in drivers/gpu/drm/i915/i915_gem_gtt.c kernel: use-after-free in cdev_put() when a PTP device is removed while it's chardev is open kernel: net/sched: cbs NULL pointer dereference when offloading is enabled kernel: cpufreq: Init completion before kobject_init_and_add() kernel: net/mlx5e: Check for NOT_READY flag state after locking kernel: Kernel: Memory leak in IPMI SSIF module leads to Denial of Service
