| CVE-2021-20196 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Advanced Virtualization and 1 more | 2024-08-03 | 6.5 Medium |
| A NULL pointer dereference flaw was found in the floppy disk emulator of QEMU. This issue occurs while processing read/write ioport commands if the selected floppy drive is not initialized with a block device. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-20213 | 1 Privoxy | 1 Privoxy | 2024-08-03 | 7.5 High |
| A flaw was found in Privoxy in versions before 3.0.29. Dereference of a NULL-pointer that could result in a crash if accept-intercepted-requests was enabled, Privoxy failed to get the request destination from the Host header and a memory allocation failed. | ||||
| CVE-2021-4236 | 1 Web Project | 1 Web | 2024-08-03 | 9.8 Critical |
| Web Sockets do not execute any AuthenticateMethod methods which may be set, leading to a nil pointer dereference if the returned UserData pointer is assumed to be non-nil, or authentication bypass. This issue only affects WebSockets with an AuthenticateMethod hook. Request handlers that do not explicitly use WebSockets are not vulnerable. | ||||
| CVE-2021-4217 | 3 Fedoraproject, Redhat, Unzip Project | 3 Fedora, Enterprise Linux, Unzip | 2024-08-03 | 3.3 Low |
| A flaw was found in unzip. The vulnerability occurs due to improper handling of Unicode strings, which can lead to a null pointer dereference. This flaw allows an attacker to input a specially crafted zip file, leading to a crash or code execution. | ||||
| CVE-2021-4209 | 3 Gnu, Netapp, Redhat | 6 Gnutls, Active Iq Unified Manager, Hci Bootstrap Os and 3 more | 2024-08-03 | 6.5 Medium |
| A NULL pointer dereference flaw was found in GnuTLS. As Nettle's hash update functions internally call memcpy, providing zero-length input may cause undefined behavior. This flaw leads to a denial of service after authentication in rare circumstances. | ||||
| CVE-2021-4186 | 2 Fedoraproject, Wireshark | 2 Fedora, Wireshark | 2024-08-03 | 6.3 Medium |

| CVE-2021-4158 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-08-03 | 6.0 Medium |
| A NULL pointer dereference issue was found in the ACPI code of QEMU. A malicious, privileged user within the guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. | ||||
| CVE-2021-4188 | 1 Mruby | 1 Mruby | 2024-08-03 | 7.5 High |
| mruby is vulnerable to NULL Pointer Dereference | ||||
| CVE-2021-4145 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-08-03 | 6.5 Medium |
| A NULL pointer dereference issue was found in the block mirror layer of QEMU in versions prior to 6.2.0. The `self` pointer is dereferenced in mirror_wait_on_conflicts() without ensuring that it's not NULL. A malicious unprivileged user within the guest could use this flaw to crash the QEMU process on the host when writing data reaches the threshold of mirroring node. | ||||
| CVE-2021-4110 | 1 Mruby | 1 Mruby | 2024-08-03 | 7.5 High |
| mruby is vulnerable to NULL Pointer Dereference | ||||
| CVE-2021-4095 | 2 Fedoraproject, Linux | 2 Fedora, Linux Kernel | 2024-08-03 | 5.5 Medium |
| A NULL pointer dereference was found in the Linux kernel's KVM when dirty ring logging is enabled without an active vCPU context. An unprivileged local attacker on the host may use this flaw to cause a kernel oops condition and thus a denial of service by issuing a KVM_XEN_HVM_SET_ATTR ioctl. This flaw affects Linux kernel versions prior to 5.17-rc1. | ||||
| CVE-2021-3659 | 3 Fedoraproject, Linux, Redhat | 17 Fedora, Linux Kernel, Codeready Linux Builder and 14 more | 2024-08-03 | 5.5 Medium |
| A NULL pointer dereference flaw was found in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-3537 | 6 Debian, Fedoraproject, Netapp and 3 more | 21 Debian Linux, Fedora, Active Iq Unified Manager and 18 more | 2024-08-03 | 5.9 Medium |
| A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-3596 | 4 Debian, Fedoraproject, Imagemagick and 1 more | 4 Debian Linux, Fedora, Imagemagick and 1 more | 2024-08-03 | 6.5 Medium |
| A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage() in coders/svg.c. This issue is due to not checking the return value from libxml2's xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault. | ||||
| CVE-2021-3543 | 3 Fedoraproject, Nitro Enclaves Project, Redhat | 3 Fedora, Nitro Enclaves, Enterprise Linux | 2024-08-03 | 6.7 Medium |
| A flaw null pointer dereference in the Nitro Enclaves kernel driver was found in the way that Enclaves VMs forces closures on the enclave file descriptor. A local user of a host machine could use this flaw to crash the system or escalate their privileges on the system. | ||||

| A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server. | ||||
| CVE-2021-3739 | 3 Fedoraproject, Linux, Netapp | 18 Fedora, Linux Kernel, H300e and 15 more | 2024-08-03 | 7.1 High |
| A NULL pointer dereference flaw was found in the btrfs_rm_device function in fs/btrfs/volumes.c in the Linux Kernel, where triggering the bug requires ‘CAP_SYS_ADMIN’. This flaw allows a local attacker to crash the system or leak kernel internal information. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-3607 | 3 Debian, Fedoraproject, Qemu | 3 Debian Linux, Fedora, Qemu | 2024-08-03 | 6.0 Medium |
| An integer overflow was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMA_REG_DSRHIGH" write from the guest due to improper input validation. This flaw allows a privileged guest user to make QEMU allocate a large amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-3502 | 2 Avahi, Redhat | 2 Avahi, Enterprise Linux | 2024-08-03 | 5.5 Medium |
