| CVE-2021-34866 | 3 Linux, Netapp, Redhat | 19 Linux Kernel, H300e, H300e Firmware and 16 more | 2024-08-04 | 7.8 High |
| This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.14-rc3. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs, which can result in a type confusion condition. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-14689. | ||||
| CVE-2021-34693 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-08-04 | 5.5 Medium |
| net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized. | ||||
| CVE-2021-34691 | 2 Idrive, Linux | 2 Remotepc, Linux Kernel | 2024-08-04 | 7.5 High |
| iDrive RemotePC before 4.0.1 on Linux allows denial of service. A remote and unauthenticated attacker can disconnect a valid user session by connecting to an ephemeral port. | ||||
| CVE-2021-34556 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2024-08-04 | 5.5 Medium |
| In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack. | ||||
| CVE-2021-34399 | 3 Linux, Microsoft, Nvidia | 137 Linux Kernel, Windows, Dgx-1 P100 and 134 more | 2024-08-04 | 4.1 Medium |
| NVIDIA GPU and Tegra hardware contain a vulnerability in the internal microcontroller which may allow a user with elevated privileges to gain access to information from unscrubbed registers, which may lead to information disclosure. | ||||
| CVE-2021-34400 | 3 Linux, Microsoft, Nvidia | 137 Linux Kernel, Windows, Dgx-1 P100 and 134 more | 2024-08-04 | 4.1 Medium |
| NVIDIA GPU and Tegra hardware contain a vulnerability in the internal microcontroller which may allow a user with elevated privileges to gain access to information from unscrubbed memory, which may lead to information disclosure. | ||||
| CVE-2021-33909 | 7 Debian, Fedoraproject, Linux and 4 more | 16 Debian Linux, Fedora, Linux Kernel and 13 more | 2024-08-04 | 7.8 High |
| fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user, aka CID-8cae8cd89f05. | ||||
| CVE-2021-33655 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2024-08-03 | 6.7 Medium |
| When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds. | ||||
| CVE-2021-33656 | 4 Debian, Huawei, Linux and 1 more | 6 Debian Linux, Openeuler, Linux Kernel and 3 more | 2024-08-03 | 6.8 Medium |
| When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds. | ||||
| CVE-2021-33624 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-08-03 | 4.7 Medium |
| In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a side-channel attack, aka CID-9183671af6db. | ||||
| CVE-2021-33391 | 2 Htacg, Linux | 2 Tidy, Linux Kernel | 2024-08-03 | 9.8 Critical |
| An issue in HTACG HTML Tidy v5.7.28 allows attacker to execute arbitrary code via the -g option of the CleanNode() function in gdoc.c. | ||||
| CVE-2021-33200 | 4 Fedoraproject, Linux, Netapp and 1 more | 20 Fedora, Linux Kernel, Cloud Backup and 17 more | 2024-08-03 | 7.8 High |
| kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit. | ||||
| CVE-2021-33254 | 2 Embedthis, Linux | 2 Appweb, Linux Kernel | 2024-08-03 | 7.5 High |
| An issue was discovered in src/http/httpLib.c in EmbedThis Appweb Community Edition 8.2.1, allows attackers to cause a denial of service via the stream paramter to the parseUri function. | ||||
| CVE-2021-33034 | 4 Debian, Fedoraproject, Linux and 1 more | 11 Debian Linux, Fedora, Linux Kernel and 8 more | 2024-08-03 | 7.8 High |
| In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. | ||||
| CVE-2021-33033 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Rhel Extras Rt | 2024-08-03 | 7.8 High |
| The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads to writing an arbitrary value. | ||||
| CVE-2021-32606 | 2 Fedoraproject, Linux | 2 Fedora, Linux Kernel | 2024-08-03 | 7.8 High |
| In the Linux kernel 5.11 through 5.12.2, isotp_setsockopt in net/can/isotp.c allows privilege escalation to root by leveraging a use-after-free. (This does not affect earlier versions that lack CAN ISOTP SF_BROADCAST support.) | ||||
| CVE-2021-32399 | 4 Debian, Linux, Netapp and 1 more | 27 Debian Linux, Linux Kernel, Cloud Backup and 24 more | 2024-08-03 | 7.0 High |
| net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI controller. | ||||
| CVE-2021-32078 | 1 Linux | 1 Linux Kernel | 2024-08-03 | 7.1 High |
| An Out-of-Bounds Read was discovered in arch/arm/mach-footbridge/personal-pci.c in the Linux kernel through 5.12.11 because of the lack of a check for a value that shouldn't be negative, e.g., access to element -2 of an array, aka CID-298a58e165e4. | ||||
| CVE-2021-31916 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2024-08-03 | 6.7 Medium |
| An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-31829 | 4 Debian, Fedoraproject, Linux and 1 more | 4 Debian Linux, Fedora, Linux Kernel and 1 more | 2024-08-03 | 5.5 Medium |
| kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel. | ||||
