| CVE-2020-15707 | 8 Canonical, Debian, Gnu and 5 more | 19 Ubuntu Linux, Debian Linux, Grub2 and 16 more | 2024-11-21 | 5.7 Medium |
| Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions. | ||||
| CVE-2020-15706 | 7 Canonical, Debian, Gnu and 4 more | 18 Ubuntu Linux, Debian Linux, Grub2 and 15 more | 2024-11-21 | 6.4 Medium |
| GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2 version 2.04 and prior versions. | ||||
| CVE-2020-15705 | 7 Canonical, Debian, Gnu and 4 more | 18 Ubuntu Linux, Debian Linux, Grub2 and 15 more | 2024-11-21 | 6.4 Medium |
| GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim. This issue affects GRUB2 version 2.04 and prior versions. | ||||
| CVE-2020-14372 | 4 Fedoraproject, Gnu, Netapp and 1 more | 13 Fedora, Grub2, Cloud Backup and 10 more | 2024-11-21 | 7.5 High |
| A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity, as well as system availability. | ||||
| CVE-2020-14364 | 6 Canonical, Debian, Fedoraproject and 3 more | 14 Ubuntu Linux, Debian Linux, Fedora and 11 more | 2024-11-21 | 5.0 Medium |
| An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host. | ||||
| CVE-2020-14351 | 3 Debian, Linux, Redhat | 8 Debian Linux, Linux Kernel, Enterprise Linux and 5 more | 2024-11-21 | 7.8 High |
| A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
| CVE-2020-14311 | 4 Canonical, Gnu, Opensuse and 1 more | 11 Ubuntu Linux, Grub2, Leap and 8 more | 2024-11-21 | 5.7 Medium |
| There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow. | ||||
| CVE-2020-14310 | 4 Canonical, Gnu, Opensuse and 1 more | 11 Ubuntu Linux, Grub2, Leap and 8 more | 2024-11-21 | 5.7 Medium |
| There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow. | ||||
| CVE-2020-14309 | 3 Gnu, Opensuse, Redhat | 7 Grub2, Leap, Enterprise Linux and 4 more | 2024-11-21 | 6.7 Medium |
| There's an issue with grub2 in all versions before 2.06 when handling squashfs filesystems containing a symbolic link with name length of UINT32 bytes in size. The name size leads to an arithmetic overflow leading to a zero-size allocation further causing a heap-based buffer overflow with attacker controlled data. | ||||
| CVE-2020-14308 | 3 Gnu, Opensuse, Redhat | 7 Grub2, Leap, Enterprise Linux and 4 more | 2024-11-21 | 6.4 Medium |
| In grub2 versions before 2.06 the grub memory allocator doesn't check for possible arithmetic overflows on the requested allocation size. This leads the function to return invalid memory allocations which can be further used to cause possible integrity, confidentiality and availability impacts during the boot process. | ||||
| CVE-2020-12888 | 7 Canonical, Debian, Fedoraproject and 4 more | 45 Ubuntu Linux, Debian Linux, Fedora and 42 more | 2024-11-21 | 5.3 Medium |
| The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space. | ||||
| CVE-2020-12770 | 6 Canonical, Debian, Fedoraproject and 3 more | 42 Ubuntu Linux, Debian Linux, Fedora and 39 more | 2024-11-21 | 6.7 Medium |
| An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040. | ||||
| CVE-2020-12723 | 6 Fedoraproject, Netapp, Opensuse and 3 more | 21 Fedora, Oncommand Workflow Automation, Snap Creator Framework and 18 more | 2024-11-21 | 7.5 High |
| regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls. | ||||
| CVE-2020-12654 | 2 Linux, Redhat | 8 Linux Kernel, Enterprise Linux, Enterprise Mrg and 5 more | 2024-11-21 | 7.1 High |
| An issue was found in Linux kernel before 5.5.4. mwifiex_ret_wmm_get_status() in drivers/net/wireless/marvell/mwifiex/wmm.c allows a remote AP to trigger a heap-based buffer overflow because of an incorrect memcpy, aka CID-3a9b153c5591. | ||||
| CVE-2020-12653 | 5 Debian, Linux, Netapp and 2 more | 42 Debian Linux, Linux Kernel, A700s and 39 more | 2024-11-21 | 7.8 High |
| An issue was found in Linux kernel before 5.5.4. The mwifiex_cmd_append_vsie_tlv() function in drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea. | ||||
| CVE-2020-12403 | 2 Mozilla, Redhat | 7 Nss, Enterprise Linux, Openshift Do and 4 more | 2024-11-21 | 9.1 Critical |
| A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. When using multi-part Chacha20, it could cause out-of-bounds reads. This issue was fixed by explicitly disabling multi-part ChaCha20 (which was not functioning correctly) and strictly enforcing tag length. The highest threat from this vulnerability is to confidentiality and system availability. | ||||
| CVE-2020-12362 | 3 Intel, Linux, Redhat | 9 Graphics Drivers, Linux Kernel, Enterprise Linux and 6 more | 2024-11-21 | 7.8 High |
| Integer overflow in the firmware for some Intel(R) Graphics Drivers for Windows * before version 26.20.100.7212 and before Linux kernel version 5.5 may allow a privileged user to potentially enable an escalation of privilege via local access. | ||||
| CVE-2020-12352 | 3 Bluez, Linux, Redhat | 8 Bluez, Linux Kernel, Enterprise Linux and 5 more | 2024-11-21 | 6.5 Medium |
| Improper access control in BlueZ may allow an unauthenticated user to potentially enable information disclosure via adjacent access. | ||||
| CVE-2020-12351 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 8.8 High |
| Improper input validation in BlueZ may allow an unauthenticated user to potentially enable escalation of privilege via adjacent access. | ||||
| CVE-2020-12321 | 2 Intel, Redhat | 27 Dual Band Wireless-ac 3165, Dual Band Wireless-ac 3165 Firmware, Dual Band Wireless-ac 3168 and 24 more | 2024-11-21 | 8.8 High |
| Improper buffer restriction in some Intel(R) Wireless Bluetooth(R) products before version 21.110 may allow an unauthenticated user to potentially enable escalation of privilege via adjacent access. | ||||
