CVE-2020-13974 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 7.8 High
An issue was discovered in the Linux kernel 4.4 through 5.7.1. drivers/tty/vt/keyboard.c has an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community argue that the integer overflow does not lead to a security issue in this case.
CVE-2020-13143 5 Canonical, Debian, Linux and 2 more 38 Ubuntu Linux, Debian Linux, Linux Kernel and 35 more 2024-11-21 6.5 Medium
gadget_dev_desc_UDC_store in drivers/usb/gadget/configfs.c in the Linux kernel 3.16 through 5.6.13 relies on kstrdup without considering the possibility of an internal '\0' value, which allows attackers to trigger an out-of-bounds read, aka CID-15753588bcd4.

An issue was discovered in the Linux kernel before 5.4.17. drivers/spi/spi-dw.c allows attackers to cause a panic via concurrent calls to dw_spi_irq and dw_spi_transfer_one, aka CID-19b61392c5a8.
CVE-2020-12768 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 5.5 Medium
An issue was discovered in the Linux kernel before 5.6. svm_cpu_uninit in arch/x86/kvm/svm.c has a memory leak, aka CID-d80b64ff297e. NOTE: third parties dispute this issue because it's a one-time leak at the boot, the size is negligible, and it can't be triggered at will
CVE-2020-12653 5 Debian, Linux, Netapp and 2 more 42 Debian Linux, Linux Kernel, A700s and 39 more 2024-11-21 7.8 High
An issue was found in Linux kernel before 5.5.4. The mwifiex_cmd_append_vsie_tlv() function in drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea.
CVE-2020-11884 6 Canonical, Debian, Fedoraproject and 3 more 38 Ubuntu Linux, Debian Linux, Fedora and 35 more 2024-11-21 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-2020-11494 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 4.4 Medium
An issue was discovered in slc_bump in drivers/net/can/slcan.c in the Linux kernel 3.16 through 5.6.2. It allows attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL, aka CID-b9258a2cece4.
CVE-2020-10942 5 Canonical, Debian, Linux and 2 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2024-11-21 5.3 Medium
In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls.
CVE-2020-10933 5 Debian, Fedoraproject, Linux and 2 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2024-11-21 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-2020-10803 5 Debian, Fedoraproject, Opensuse and 2 more 7 Debian Linux, Fedora, Backports Sle and 4 more 2024-11-21 5.4 Medium
In phpMyAdmin 4.x before 4.9.5 and 5.x before 5.0.2, a SQL injection vulnerability was discovered where malicious code could be used to trigger an XSS attack through retrieving and displaying results (in tbl_get_field.php and libraries/classes/Display/Results.php). The attacker must be able to insert crafted data into certain database tables, which when retrieved (for instance, through the Browse tab) can trigger the XSS attack.
CVE-2020-10802 5 Debian, Fedoraproject, Opensuse and 2 more 7 Debian Linux, Fedora, Backports Sle and 4 more 2024-11-21 8.0 High
In phpMyAdmin 4.x before 4.9.5 and 5.x before 5.0.2, a SQL injection vulnerability has been discovered where certain parameters are not properly escaped when generating certain queries for search actions in libraries/classes/Controllers/Table/TableSearchController.php. An attacker can generate a crafted database or table name. The attack can be performed if a user attempts certain search operations on the malicious database or table.
CVE-2020-10781 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-11-21 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-2020-10757 7 Canonical, Debian, Fedoraproject and 4 more 13 Ubuntu Linux, Debian Linux, Fedora and 10 more 2024-11-21 7.8 High
A flaw was found in the Linux Kernel in versions after 4.5-rc1 in the way mremap handled DAX Huge Pages. This flaw allows a local attacker with access to a DAX enabled storage to escalate their privileges on the system.
CVE-2020-10711 5 Canonical, Debian, Linux and 2 more 17 Ubuntu Linux, Debian Linux, Linux Kernel and 14 more 2024-11-21 5.9 Medium
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service.
CVE-2020-10690 6 Canonical, Debian, Linux and 3 more 34 Ubuntu Linux, Debian Linux, Linux Kernel and 31 more 2024-11-21 6.5 Medium
There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode.
CVE-2019-9213 5 Canonical, Debian, Linux and 2 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2024-11-21 5.5 Medium
In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task.
CVE-2019-8980 5 Canonical, Debian, Linux and 2 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2024-11-21 7.5 High
A memory leak in the kernel_read_file function in fs/exec.c in the Linux kernel through 4.20.11 allows attackers to cause a denial of service (memory consumption) by triggering vfs_read failures.
