CVE-2021-33655 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-11-21 N/A 6.7 MEDIUM
When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds.
CVE-2021-33624 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-11-21 4.7 MEDIUM 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-2021-33254 2 Embedthis, Linux 2 Appweb, Linux Kernel 2024-11-21 5.0 MEDIUM 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-2021-33200 3 Fedoraproject, Linux, Netapp 19 Fedora, Linux Kernel, Cloud Backup and 16 more 2024-11-21 7.2 HIGH 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-2021-33034 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 4.6 MEDIUM 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 1 Linux 1 Linux Kernel 2024-11-21 4.6 MEDIUM 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 2024-11-21 7.2 HIGH 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 3 Debian, Linux, Netapp 19 Debian Linux, Linux Kernel, Cloud Backup and 16 more 2024-11-21 4.4 MEDIUM 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 2024-11-21 6.6 MEDIUM 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 2024-11-21 6.1 MEDIUM 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 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 2.1 LOW 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.
CVE-2021-31822 2 Linux, Octopus 2 Linux Kernel, Tentacle 2024-11-21 4.6 MEDIUM 7.8 HIGH
When Octopus Tentacle is installed on a Linux operating system, the systemd service file permissions are misconfigured. This could lead to a local unprivileged user modifying the contents of the systemd service file to gain privileged access.
CVE-2021-31820 3 Linux, Microsoft, Octopus 3 Linux Kernel, Windows, Octopus Server 2024-11-21 5.0 MEDIUM 7.5 HIGH
In Octopus Server after version 2018.8.2 if the Octopus Server Web Request Proxy is configured with authentication, the password is shown in plaintext in the UI.
CVE-2021-31440 2 Linux, Netapp 18 Linux Kernel, Cloud Backup, H300e and 15 more 2024-11-21 6.9 MEDIUM 7.0 HIGH
This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.11.15. 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 prior to executing them. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-13661.
CVE-2021-30565 3 Fedoraproject, Google, Linux 4 Fedora, Chrome, Chrome Os and 1 more 2024-11-21 6.8 MEDIUM 8.8 HIGH
Out of bounds write in Tab Groups in Google Chrome on Linux and ChromeOS prior to 92.0.4515.107 allowed an attacker who convinced a user to install a malicious extension to perform an out of bounds memory write via a crafted HTML page.
CVE-2021-30178 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2024-11-21 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel through 5.11.11. synic_get in arch/x86/kvm/hyperv.c has a NULL pointer dereference for certain accesses to the SynIC Hyper-V context, aka CID-919f4ebc5987.
CVE-2021-30002 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-11-21 2.1 LOW 6.2 MEDIUM
An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.
CVE-2021-29987 2 Linux, Mozilla 3 Linux Kernel, Firefox, Thunderbird 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
After requesting multiple permissions, and closing the first permission panel, subsequent permission panels will be displayed in a different position but still record a click in the default location, making it possible to trick a user into accepting a permission they did not want to. *This bug only affects Firefox on Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 91 and Thunderbird < 91.
CVE-2021-29986 2 Linux, Mozilla 4 Linux Kernel, Firefox, Firefox Esr and 1 more 2024-11-21 6.8 MEDIUM 8.1 HIGH
A suspected race condition when calling getaddrinfo led to memory corruption and a potentially exploitable crash. *Note: This issue only affected Linux operating systems. Other operating systems are unaffected.* This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
CVE-2021-29907 3 Ibm, Linux, Microsoft 3 Openpages With Watson, Linux Kernel, Windows 2024-11-21 6.5 MEDIUM 8.8 HIGH
IBM OpenPages with Watson 8.1 and 8.2 could allow an authenticated user to upload a file that could execute arbitrary code on the system. IBM X-Force ID: 207633.
