|---|---|---|---|---|
| CVE-2020-29372 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-08-04 | 4.7 Medium |
| An issue was discovered in do_madvise in mm/madvise.c in the Linux kernel before 5.6.8. There is a race condition between coredump operations and the IORING_OP_MADVISE implementation, aka CID-bc0c4d1e176e. | ||||
| CVE-2020-29374 | 3 Debian, Linux, Netapp | 11 Debian Linux, Linux Kernel, 500f and 8 more | 2024-08-04 | 3.6 Low |
| An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/huge_memory.c. The get_user_pages (aka gup) implementation, when used for a copy-on-write page, does not properly consider the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58. | ||||
| CVE-2020-29371 | 1 Linux | 1 Linux Kernel | 2024-08-04 | 3.3 Low |
| An issue was discovered in romfs_dev_read in fs/romfs/storage.c in the Linux kernel before 5.8.4. Uninitialized memory leaks to userspace, aka CID-bcf85fcedfdd. | ||||
| CVE-2020-29373 | 1 Linux | 1 Linux Kernel | 2024-08-04 | 6.5 Medium |
| An issue was discovered in fs/io_uring.c in the Linux kernel before 5.6. It unsafely handles the root directory during path lookups, and thus a process inside a mount namespace can escape to unintended filesystem locations, aka CID-ff002b30181d. | ||||
| CVE-2020-29369 | 2 Linux, Netapp | 5 Linux Kernel, Hci Compute Node, Hci Management Node and 2 more | 2024-08-04 | 7.0 High |
| An issue was discovered in mm/mmap.c in the Linux kernel before 5.7.11. There is a race condition between certain expand functions (expand_downwards and expand_upwards) and page-table free operations from an munmap call, aka CID-246c320a8cfe. | ||||
| CVE-2020-29370 | 2 Linux, Netapp | 10 Linux Kernel, Cloud Backup, H410c and 7 more | 2024-08-04 | 7.0 High |
| An issue was discovered in kmem_cache_alloc_bulk in mm/slub.c in the Linux kernel before 5.5.11. The slowpath lacks the required TID increment, aka CID-fd4d9c7d0c71. | ||||
| CVE-2020-29368 | 3 Linux, Netapp, Redhat | 11 Linux Kernel, Cloud Backup, Element Software and 8 more | 2024-08-04 | 7.0 High |
| An issue was discovered in __split_huge_pmd in mm/huge_memory.c in the Linux kernel before 5.7.5. The copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check, aka CID-c444eb564fb1. | ||||
| CVE-2020-28974 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2024-08-04 | 5.0 Medium |
| A slab-out-of-bounds read in fbcon in the Linux kernel before 5.9.7 could be used by local attackers to read privileged information or potentially crash the kernel, aka CID-3c4e0dff2095. This occurs because KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for manipulations such as font height. | ||||
| CVE-2020-28941 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2024-08-04 | 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-2020-28915 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Rhev Hypervisor | 2024-08-04 | 5.8 Medium |
| A buffer over-read (at the framebuffer layer) in the fbcon code in the Linux kernel before 5.8.15 could be used by local attackers to read kernel memory, aka CID-6735b4632def. | ||||
| CVE-2020-28588 | 1 Linux | 1 Linux Kernel | 2024-08-04 | 5.5 Medium |
| An information disclosure vulnerability exists in the /proc/pid/syscall functionality of Linux Kernel 5.1 Stable and 5.4.66. More specifically, this issue has been introduced in v5.1-rc4 (commit 631b7abacd02b88f4b0795c08b54ad4fc3e7c7c0) and is still present in v5.10-rc4, so it’s likely that all versions in between are affected. An attacker can read /proc/pid/syscall to trigger this vulnerability, which leads to the kernel leaking memory contents. | ||||
| CVE-2020-28374 | 4 Debian, Fedoraproject, Linux and 1 more | 9 Debian Linux, Fedora, Linux Kernel and 6 more | 2024-08-04 | 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-2020-28097 | 2 Linux, Netapp | 18 Linux Kernel, Cloud Backup, H300e and 15 more | 2024-08-04 | 5.9 Medium |
| The vgacon subsystem in the Linux kernel before 5.8.10 mishandles software scrollback. There is a vgacon_scrolldelta out-of-bounds read, aka CID-973c096f6a85. | ||||
| CVE-2020-27786 | 3 Linux, Netapp, Redhat | 6 Linux Kernel, Cloud Backup, Solidfire Baseboard Management Controller and 3 more | 2024-08-04 | 7.8 High |
| A flaw was found in the Linux kernel’s implementation of MIDI, where an attacker with a local account and the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to this specific memory while freed and before use causes the flow of execution to change and possibly allow for memory corruption or privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | ||||
| CVE-2020-27825 | 4 Debian, Linux, Netapp and 1 more | 9 Debian Linux, Linux Kernel, Cloud Backup and 6 more | 2024-08-04 | 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-2020-27830 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-08-04 | 5.5 Medium |
| A vulnerability was found in Linux Kernel where in the spk_ttyio_receive_buf2() function, it would dereference spk_ttyio_synth without checking whether it is NULL or not, and may lead to a NULL-ptr deref crash. | ||||
| CVE-2020-27815 | 3 Debian, Linux, Netapp | 22 Debian Linux, Linux Kernel, Aff A250 and 19 more | 2024-08-04 | 7.8 High |
| A flaw was found in the JFS filesystem code in the Linux Kernel which allows a local attacker with the ability to set extended attributes to panic the system, causing memory corruption or escalating privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | ||||
| CVE-2020-27820 | 4 Fedoraproject, Linux, Oracle and 1 more | 6 Fedora, Linux Kernel, Communications Cloud Native Core Binding Support Function and 3 more | 2024-08-04 | 4.7 Medium |
| A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could happen if removing device (that is not common to remove video card physically without power-off, but same happens if "unbind" the driver). | ||||
| CVE-2020-27784 | 1 Linux | 1 Linux Kernel | 2024-08-04 | 5.5 Medium |
| A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl() printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had been freed by gprinter_free(). | ||||
| CVE-2020-27777 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Openshift Container Platform | 2024-08-04 | 6.7 Medium |
| A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries platform) a root like local user could use this flaw to further increase their privileges to that of a running kernel. | ||||
