title: Red Hat Security Advisory: kernel security, bug fix, and enhancement update
description: kernel: out of bound read in DVB connexant driver. kernel: Missing permissions check for request_key() destination allows local attackers to add keys to keyring without Write permission kernel: denial of service via ioctl call in network tun handling kernel: oob memory read in hso_probe in drivers/net/usb/hso.c kernel: usb: missing size check in the __usb_get_extra_descriptor() leading to DoS kernel: perf_event_open() and execve() race in setuid programs allows a data leak kernel: triggering AP to send IAPP location updates for stations before the required authentication process has completed can lead to DoS kernel: brcmfmac frame validation bypass kernel: null-pointer dereference in hci_uart_set_flow_control Kernel: net: weak IP ID generation leads to remote device tracking Kernel: net: using kernel space address bits to derive IP ID may potentially break KASLR kernel: ASLR bypass for setuid binaries due to late install_exec_creds() kernel: sensitive information disclosure from kernel stack memory via HIDPCONNADD command kernel: unchecked kstrdup of fwstr in drm_load_edid_firmware leads to denial of service kernel: use-after-free in arch/x86/lib/insn-eval.c kernel: denial of service in arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c via sigreturn() system call kernel: integer overflow and OOB read in drivers/block/floppy.c kernel: heap overflow in mwifiex_set_uap_rates() function of Marvell Wifi Driver leading to DoS kernel: heap-overflow in mwifiex_set_wmm_params() function of Marvell WiFi driver leading to DoS kernel: An out-of-bounds read in drivers/scsi/qedi/qedi_dbg.c leading to crash or information disclosure kernel: use-after-free in sound/core/init.c and sound/core/info.c kernel: Null pointer dereference in the sound/usb/line6/pcm.c kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c leads to denial of service kernel: buffer-overflow hardening in WiFi beacon validation code. kernel: powerpc: incomplete Spectre-RSB mitigation leads to information exposure
