Date Id Summary Products Score Patch Annotated
2021-03-23 CVE-2021-20219 A denial of service vulnerability was found in n_tty_receive_char_special in drivers/tty/n_tty.c of the Linux kernel. In this flaw a local attacker with a normal user privilege could delay the loop (due to a changing ldata->read_head, and a missing sanity check) and cause a threat to the system availability. Linux_kernel 5.5
2020-10-13 CVE-2020-25645 A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. Ubuntu_linux, Debian_linux, Linux_kernel, Hci_compute_node_bios, Solidfire_\&_hci_management_node, Solidfire_\&_hci_storage_node, Leap 7.5
2021-03-11 CVE-2021-20261 A race condition was found in the Linux kernels implementation of the floppy disk drive controller driver software. The impact of this issue is lessened by the fact that the default permissions on the floppy device (/dev/fd0) are restricted to root. If the permissions on the device have changed the impact changes greatly. In the default configuration root (or equivalent) permissions are required to attack this flaw. Linux_kernel, Enterprise_linux 6.4
2019-11-28 CVE-2019-19318 In the Linux kernel 5.3.11, mounting a crafted btrfs image twice can cause an rwsem_down_write_slowpath use-after-free because (in rwsem_can_spin_on_owner in kernel/locking/rwsem.c) rwsem_owner_flags returns an already freed pointer, Ubuntu_linux, Debian_linux, Linux_kernel, Active_iq_unified_manager, Aff_a400_firmware, Aff_a700s_firmware, Data_availability_services, Fas8300_firmware, Fas8700_firmware, H610s_firmware, Hci_management_node, Solidfire, Steelstore_cloud_integrated_storage, Leap 4.4
2019-12-17 CVE-2019-19813 In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in __mutex_lock in kernel/locking/mutex.c. This is related to mutex_can_spin_on_owner in kernel/locking/mutex.c, __btrfs_qgroup_free_meta in fs/btrfs/qgroup.c, and btrfs_insert_delayed_items in fs/btrfs/delayed-inode.c. Ubuntu_linux, Debian_linux, Linux_kernel, Active_iq_unified_manager, Aff_a400_firmware, Aff_a700s_firmware, Data_availability_services, Fas8300_firmware, Fas8700_firmware, H610s_firmware, Hci_management_node, Solidfire, Steelstore_cloud_integrated_storage 5.5
2019-11-27 CVE-2019-19319 In the Linux kernel before 5.2, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call, aka CID-345c0dbf3a30. Linux_kernel, Leap, Enterprise_linux 6.5
2018-08-07 CVE-2018-5953 The swiotlb_print_info function in lib/swiotlb.c in the Linux kernel through 4.14.14 allows local users to obtain sensitive address information by reading dmesg data from a "software IO TLB" printk call. Debian_linux, Linux_kernel 5.5
2020-11-20 CVE-2020-28974 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. Debian_linux, Linux_kernel 5.0
2020-09-10 CVE-2020-25220 The Linux kernel 4.9.x before 4.9.233, 4.14.x before 4.14.194, and 4.19.x before 4.19.140 has a use-after-free because skcd->no_refcnt was not considered during a backport of a CVE-2020-14356 patch. This is related to the cgroups feature. Linux_kernel 7.8
2020-11-28 CVE-2019-20934 An issue was discovered in the Linux kernel before 5.2.6. On NUMA systems, the Linux fair scheduler has a use-after-free in show_numa_stats() because NUMA fault statistics are inappropriately freed, aka CID-16d51a590a8c. Linux_kernel 5.3
