| CVE-2020-28941 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2023-11-07 | 4.9 MEDIUM | 5.5 MEDIUM |
| An issue was discovered in drivers/accessibility/speakup/spk_ttyio.c in the Linux kernel through 5.9.9. Local attackers on systems with the speakup driver could cause a local denial of service attack, aka CID-d41227544427. This occurs because of an invalid free when the line discipline is used more than once. | |||||
| CVE-2020-28374 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2023-11-07 | 5.5 MEDIUM | 8.1 HIGH |
| In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are proxied via an attacker-selected backstore. | |||||
| CVE-2020-27825 | 4 Debian, Linux, Netapp and 1 more | 9 Debian Linux, Linux Kernel, Cloud Backup and 6 more | 2023-11-07 | 5.4 MEDIUM | 5.7 MEDIUM |
| A use-after-free flaw was found in kernel/trace/ring_buffer.c in Linux kernel (before 5.10-rc1). There was a race problem in trace_open and resize of cpu buffer running parallely on different cpus, may cause a denial of service problem (DOS). This flaw could even allow a local attacker with special user privilege to a kernel information leak threat. | |||||
| CVE-2020-27675 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2023-11-07 | 4.7 MEDIUM | 4.7 MEDIUM |
| An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash via events for an in-reconfiguration paravirtualized device, aka CID-073d0552ead5. | |||||
| CVE-2020-27171 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-11-07 | 3.6 LOW | 6.0 MEDIUM |
| An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error (with a resultant integer underflow) affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-10d2bb2e6b1d. | |||||
| CVE-2020-27170 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-11-07 | 1.9 LOW | 4.7 MEDIUM |
| An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit. | |||||
| CVE-2020-26558 | 5 Bluetooth, Debian, Fedoraproject and 2 more | 34 Bluetooth Core Specification, Debian Linux, Fedora and 31 more | 2023-11-07 | 4.3 MEDIUM | 4.2 MEDIUM |
| Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time. | |||||
| CVE-2020-25669 | 3 Debian, Linux, Netapp | 21 Debian Linux, Linux Kernel, Cloud Backup and 18 more | 2023-11-07 | 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 | 2023-11-07 | 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-2020-25639 | 3 Fedoraproject, Linux, Redhat | 5 Fedora, Linux Kernel, Enterprise Linux and 2 more | 2023-11-07 | 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-2020-25211 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2023-11-07 | 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-2020-1749 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Enterprise Mrg | 2023-11-07 | 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. | |||||
| CVE-2020-16166 | 7 Canonical, Debian, Fedoraproject and 4 more | 16 Ubuntu Linux, Debian Linux, Fedora and 13 more | 2023-11-07 | 4.3 MEDIUM | 3.7 LOW |
| The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c. | |||||
| CVE-2020-16119 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2023-11-07 | 4.6 MEDIUM | 7.8 HIGH |
| Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP socket with an attached dccps_hc_tx_ccid object as a listener after being released. Fixed in Ubuntu Linux kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and 3.2.0-149.196. | |||||
| CVE-2020-14386 | 4 Debian, Fedoraproject, Linux and 1 more | 4 Debian Linux, Fedora, Linux Kernel and 1 more | 2023-11-07 | 7.2 HIGH | 7.8 HIGH |
| A flaw was found in the Linux kernel before 5.9-rc4. Memory corruption can be exploited to gain root privileges from unprivileged processes. The highest threat from this vulnerability is to data confidentiality and integrity. | |||||
| CVE-2020-14385 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2023-11-07 | 4.7 MEDIUM | 5.5 MEDIUM |
| A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading to a denial of service. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2020-14314 | 4 Canonical, Debian, Linux and 1 more | 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more | 2023-11-07 | 2.1 LOW | 5.5 MEDIUM |
| A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash the system if the directory exists. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2020-14305 | 2 Linux, Netapp | 10 Linux Kernel, A250, A250 Firmware and 7 more | 2023-11-07 | 8.3 HIGH | 8.1 HIGH |
| An out-of-bounds memory write flaw was found in how the Linux kernel’s Voice Over IP H.323 connection tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote user to crash the system, causing a denial of service. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | |||||
