CVE-2020-25669 3 Debian, Linux, Netapp 21 Debian Linux, Linux Kernel, Cloud Backup and 18 more 2024-11-21 7.2 HIGH 7.8 HIGH
A vulnerability was found in the Linux Kernel where the function sunkbd_reinit having been scheduled by sunkbd_interrupt before sunkbd being freed. Though the dangling pointer is set to NULL in sunkbd_disconnect, there is still an alias in sunkbd_reinit causing Use After Free.
CVE-2020-25668 3 Debian, Linux, Netapp 26 Debian Linux, Linux Kernel, 500f and 23 more 2024-11-21 6.9 MEDIUM 7.0 HIGH
A flaw was found in Linux Kernel because access to the global variable fg_console is not properly synchronized leading to a use after free in con_font_op.
CVE-2020-25656 4 Debian, Linux, Redhat and 1 more 4 Debian Linux, Linux Kernel, Enterprise Linux and 1 more 2024-11-21 1.9 LOW 4.1 MEDIUM
A flaw was found in the Linux kernel. A use-after-free was found in the way the console subsystem was using ioctls KDGKBSENT and KDSKBSENT. A local user could use this flaw to get read memory access out of bounds. The highest threat from this vulnerability is to data confidentiality.
CVE-2020-25645 5 Canonical, Debian, Linux and 2 more 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.
CVE-2020-25643 6 Debian, Linux, Netapp and 3 more 7 Debian Linux, Linux Kernel, H410c and 4 more 2024-11-21 7.5 HIGH 7.2 HIGH
A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause the system to crash or cause a denial of service. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25641 5 Canonical, Debian, Linux and 2 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-25639 3 Fedoraproject, Linux, Redhat 5 Fedora, Linux Kernel, Enterprise Linux and 2 more 2024-11-21 4.9 MEDIUM 4.4 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel's GPU Nouveau driver functionality in versions prior to 5.12-rc1 in the way the user calls ioctl DRM_IOCTL_NOUVEAU_CHANNEL_ALLOC. This flaw allows a local user to crash the system.
CVE-2020-25285 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 4.4 MEDIUM 6.4 MEDIUM
A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact, aka CID-17743798d812.
CVE-2020-25284 3 Debian, Linux, Opensuse 3 Debian Linux, Linux Kernel, Leap 2024-11-21 1.9 LOW 4.1 MEDIUM
The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap rbd block devices, aka CID-f44d04e696fe.
CVE-2020-25221 2 Linux, Netapp 6 Linux Kernel, Cloud Backup, Hci Compute Node and 3 more 2024-11-21 7.2 HIGH 7.8 HIGH
get_gate_page in mm/gup.c in the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows privilege escalation because of incorrect reference counting (caused by gate page mishandling) of the struct page that backs the vsyscall page. The result is a refcount underflow. This can be triggered by any 64-bit process that can use ptrace() or process_vm_readv(), aka CID-9fa2dd946743.
CVE-2020-25220 1 Linux 1 Linux Kernel 2024-11-21 7.2 HIGH 7.8 HIGH
The Linux kernel 4.9.x before 4.9.233, 4.14.x before 4.14.194, and 4.19.x before 4.19.140 has a use-after-free because skcd->no_refcnt was not considered during a backport of a CVE-2020-14356 patch. This is related to the cgroups feature.
CVE-2020-25212 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 4.4 MEDIUM 7.0 HIGH
A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452.
CVE-2020-25211 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 3.6 LOW 6.0 MEDIUM
In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.
CVE-2020-24588 8 Arista, Cisco, Debian and 5 more 350 C-100, C-100 Firmware, C-110 and 347 more 2024-11-21 2.9 LOW 3.5 LOW
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets.
CVE-2020-24587 6 Arista, Cisco, Debian and 3 more 332 C-100, C-100 Firmware, C-110 and 329 more 2024-11-21 1.8 LOW 2.6 LOW
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed.
CVE-2020-24586 5 Arista, Debian, Ieee and 2 more 44 C-200, C-200 Firmware, C-230 and 41 more 2024-11-21 2.9 LOW 3.5 LOW
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
CVE-2020-24490 2 Bluez, Linux 2 Bluez, Linux Kernel 2024-11-21 3.3 LOW 6.5 MEDIUM
Improper buffer restrictions in BlueZ may allow an unauthenticated user to potentially enable denial of service via adjacent access. This affects all Linux kernel versions that support BlueZ.
CVE-2020-24394 5 Canonical, Linux, Opensuse and 2 more 5 Ubuntu Linux, Linux Kernel, Leap and 2 more 2024-11-21 3.6 LOW 7.1 HIGH
In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered.
CVE-2020-20950 5 Apple, Ietf, Linux and 2 more 5 Macos, Public Key Cryptography Standards \#1, Linux Kernel and 2 more 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
Bleichenbacher's attack on PKCS #1 v1.5 padding for RSA in Microchip Libraries for Applications 2018-11-26 All up to 2018-11-26. The vulnerability can allow one to use Bleichenbacher's oracle attack to decrypt an encrypted ciphertext by making successive queries to the server using the vulnerable library, resulting in remote information disclosure.
CVE-2020-1749 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Enterprise Mrg 2024-11-21 5.0 MEDIUM 7.5 HIGH
A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.
