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.
CVE-2020-12888 6 Canonical, Debian, Fedoraproject and 3 more 39 Ubuntu Linux, Debian Linux, Fedora and 36 more 2023-11-07 4.7 MEDIUM 5.3 MEDIUM
The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space.
CVE-2020-12770 5 Canonical, Debian, Fedoraproject and 2 more 36 Ubuntu Linux, Debian Linux, Fedora and 33 more 2023-11-07 4.6 MEDIUM 6.7 MEDIUM
An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040.
CVE-2020-12655 1 Linux 1 Linux Kernel 2023-11-07 2.1 LOW 5.5 MEDIUM
An issue was discovered in xfs_agf_verify in fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through 5.6.10. Attackers may trigger a sync of excessive duration via an XFS v5 image with crafted metadata, aka CID-d0c7feaf8767.
CVE-2020-11884 5 Canonical, Debian, Fedoraproject and 2 more 35 Ubuntu Linux, Debian Linux, Fedora and 32 more 2023-11-07 6.9 MEDIUM 7.0 HIGH
In the Linux kernel 4.19 through 5.6.7 on the s390 platform, code execution may occur because of a race condition, as demonstrated by code in enable_sacf_uaccess in arch/s390/lib/uaccess.c that fails to protect against a concurrent page table upgrade, aka CID-3f777e19d171. A crash could also occur.
CVE-2020-11584 2 Linux, Plesk 2 Linux Kernel, Onyx 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
A GET-based XSS reflected vulnerability in Plesk Onyx 17.8.11 allows remote unauthenticated users to inject arbitrary JavaScript, HTML, or CSS via a GET parameter.
CVE-2020-10933 4 Debian, Fedoraproject, Linux and 1 more 4 Debian Linux, Fedora, Linux Kernel and 1 more 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in Ruby 2.5.x through 2.5.7, 2.6.x through 2.6.5, and 2.7.0. If a victim calls BasicSocket#read_nonblock(requested_size, buffer, exception: false), the method resizes the buffer to fit the requested size, but no data is copied. Thus, the buffer string provides the previous value of the heap. This may expose possibly sensitive data from the interpreter.
CVE-2020-10781 2 Debian, Linux 2 Debian Linux, Linux Kernel 2023-11-07 4.9 MEDIUM 5.5 MEDIUM
A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable.
CVE-2020-10773 1 Linux 1 Linux Kernel 2023-11-07 2.1 LOW 4.4 MEDIUM
A stack information leak flaw was found in s390/s390x in the Linux kernel’s memory manager functionality, where it incorrectly writes to the /proc/sys/vm/cmm_timeout file. This flaw allows a local user to see the kernel data.
CVE-2020-10768 1 Linux 1 Linux Kernel 2023-11-07 2.1 LOW 5.5 MEDIUM
A flaw was found in the Linux Kernel before 5.8-rc1 in the prctl() function, where it can be used to enable indirect branch speculation after it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens the system to Spectre v2 attacks. The highest threat from this vulnerability is to confidentiality.
