CVE-2020-10942 | 4 Canonical, Debian, Linux and 1 more | 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more | 2024-11-21 | 5.4 MEDIUM | 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 | 4 Debian, Fedoraproject, Linux and 1 more | 4 Debian Linux, Fedora, Linux Kernel and 1 more | 2024-11-21 | 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 | 2024-11-21 | 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-2020-10774 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
A memory disclosure flaw was found in the Linux kernel's versions before 4.18.0-193.el8 in the sysctl subsystem when reading the /proc/sys/kernel/rh_features file.

CVE-2020-10768 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 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. | |||||
CVE-2020-10767 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 1.9 LOW | 5.5 MEDIUM |
A flaw was found in the Linux kernel before 5.8-rc1 in the implementation of the Enhanced IBPB (Indirect Branch Prediction Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to perform a Spectre V2 style attack when this configuration is active. The highest threat from this vulnerability is to confidentiality. | |||||
CVE-2020-10766 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
A logic bug flaw was found in Linux kernel before 5.8-rc1 in the implementation of SSBD. A bug in the logic handling allows an attacker with a local account to disable SSBD protection during a context switch when additional speculative execution mitigations are in place. This issue was introduced when the per task/process conditional STIPB switching was added on top of the existing SSBD switching. The highest threat from this vulnerability is to confidentiality. | |||||
CVE-2020-10757 | 7 Canonical, Debian, Fedoraproject and 4 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2024-11-21 | 6.9 MEDIUM | 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. | |||||

A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. This flaw allows an attacker with local access to crash the system. | |||||
CVE-2020-10711 | 5 Canonical, Debian, Linux and 2 more | 11 Ubuntu Linux, Debian Linux, Linux Kernel and 8 more | 2024-11-21 | 4.3 MEDIUM | 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 | 33 Ubuntu Linux, Debian Linux, Linux Kernel and 30 more | 2024-11-21 | 4.4 MEDIUM | 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-2020-0561 | 4 Intel, Linux, Microsoft and 1 more | 5 Software Guard Extensions Sdk, Linux Kernel, Windows and 2 more | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
Improper initialization in the Intel(R) SGX SDK before v2.6.100.1 may allow an authenticated user to potentially enable escalation of privilege via local access. | |||||
CVE-2019-9857 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 4.9 MEDIUM | 5.5 MEDIUM |
In the Linux kernel through 5.0.2, the function inotify_update_existing_watch() in fs/notify/inotify/inotify_user.c neglects to call fsnotify_put_mark() with IN_MASK_CREATE after fsnotify_find_mark(), which will cause a memory leak (aka refcount leak). Finally, this will cause a denial of service. | |||||
CVE-2019-9500 | 2 Broadcom, Linux | 2 Brcmfmac Driver, Linux Kernel | 2024-11-21 | 7.9 HIGH | 7.9 HIGH |
The Broadcom brcmfmac WiFi driver prior to commit 1b5e2423164b3670e8bc9174e4762d297990deff is vulnerable to a heap buffer overflow. If the Wake-up on Wireless LAN functionality is configured, a malicious event frame can be constructed to trigger an heap buffer overflow in the brcmf_wowl_nd_results function. This vulnerability can be exploited with compromised chipsets to compromise the host, or when used in combination with CVE-2019-9503, can be used remotely. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions. | |||||
CVE-2019-9213 | 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 |
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-2019-9162 | 3 Canonical, Linux, Netapp | 7 Ubuntu Linux, Linux Kernel, Cn1610 and 4 more | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
In the Linux kernel before 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP NAT module has insufficient ASN.1 length checks (aka an array index error), making out-of-bounds read and write operations possible, leading to an OOPS or local privilege escalation. This affects snmp_version and snmp_helper. | |||||
CVE-2019-9003 | 4 Canonical, Linux, Netapp and 1 more | 8 Ubuntu Linux, Linux Kernel, Cn1610 and 5 more | 2024-11-21 | 7.8 HIGH | 7.5 HIGH |
In the Linux kernel before 4.20.5, attackers can trigger a drivers/char/ipmi/ipmi_msghandler.c use-after-free and OOPS by arranging for certain simultaneous execution of the code, as demonstrated by a "service ipmievd restart" loop. |
