RHSA-2020:1016-01 -- Redhat kernel, python-perf, perfID: oval:org.secpod.oval:def:503608 | Date: (C)2020-03-03 (M)2024-05-20 |
Class: PATCH | Family: unix |
The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * 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: 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: brcmfmac frame validation bypass * kernel: null-pointer dereference in hci_uart_set_flow_control * 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: 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: incomplete Spectre-RSB mitigation leads to information exposure * kernel: oob memory read in hso_probe in drivers/net/usb/hso.c * 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 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.
