CVE-2020-29660 5 Broadcom, Debian, Fedoraproject and 2 more 17 Fabric Operating System, Debian Linux, Fedora and 14 more 2024-11-21 2.1 LOW 4.4 MEDIUM
A locking inconsistency issue was discovered in the tty subsystem of the Linux kernel through 5.9.13. drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c may allow a read-after-free attack against TIOCGSID, aka CID-c8bcd9c5be24.
CVE-2020-29569 4 Debian, Linux, Netapp and 1 more 7 Debian Linux, Linux Kernel, Hci Compute Node and 4 more 2024-11-21 7.2 HIGH 8.8 HIGH
An issue was discovered in the Linux kernel through 5.10.1, as used with Xen through 4.14.x. The Linux kernel PV block backend expects the kernel thread handler to reset ring->xenblkd to NULL when stopped. However, the handler may not have time to run if the frontend quickly toggles between the states connect and disconnect. As a consequence, the block backend may re-use a pointer after it was freed. A misbehaving guest can trigger a dom0 crash by continuously connecting / disconnecting a block frontend. Privilege escalation and information leaks cannot be ruled out. This only affects systems with a Linux blkback.
CVE-2020-29534 1 Linux 1 Linux Kernel 2024-11-21 7.2 HIGH 7.8 HIGH
An issue was discovered in the Linux kernel before 5.9.3. io_uring takes a non-refcounted reference to the files_struct of the process that submitted a request, causing execve() to incorrectly optimize unshare_fd(), aka CID-0f2122045b94.
CVE-2020-29384 3 Advsys, Apple, Linux 3 Pngout, Macos, Linux Kernel 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in PNGOUT 2020-01-15. When compressing a crafted PNG file, it encounters an integer overflow.
CVE-2020-29374 3 Debian, Linux, Netapp 11 Debian Linux, Linux Kernel, 500f and 8 more 2024-11-21 3.3 LOW 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-2020-29373 1 Linux 1 Linux Kernel 2024-11-21 2.1 LOW 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-2020-29372 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-11-21 4.7 MEDIUM 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-2020-29371 1 Linux 1 Linux Kernel 2024-11-21 2.1 LOW 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-2020-29370 2 Linux, Netapp 10 Linux Kernel, Cloud Backup, H410c and 7 more 2024-11-21 4.4 MEDIUM 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-2020-29369 2 Linux, Netapp 5 Linux Kernel, Hci Compute Node, Hci Management Node and 2 more 2024-11-21 6.9 MEDIUM 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-2020-29368 2 Linux, Netapp 9 Linux Kernel, Cloud Backup, Element Software and 6 more 2024-11-21 6.9 MEDIUM 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 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-11-21 6.1 MEDIUM 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 2024-11-21 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-2020-28915 1 Linux 1 Linux Kernel 2024-11-21 6.1 MEDIUM 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 2024-11-21 2.1 LOW 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 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 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-2020-28097 2 Linux, Netapp 18 Linux Kernel, Cloud Backup, H300e and 15 more 2024-11-21 3.6 LOW 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-2020-27830 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-11-21 2.1 LOW 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-2020-27825 4 Debian, Linux, Netapp and 1 more 9 Debian Linux, Linux Kernel, Cloud Backup and 6 more 2024-11-21 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-2020-27820 3 Fedoraproject, Linux, Oracle 5 Fedora, Linux Kernel, Communications Cloud Native Core Binding Support Function and 2 more 2024-11-21 4.7 MEDIUM 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).
