| CVE-2021-20317 | Med | 0.22 | 4.4 | 0.00 | Sep 27, 2021 | A flaw was found in the Linux kernel. A corrupted timer tree caused the task wakeup to be missing in the timerqueue_add function in lib/timerqueue.c. This flaw allows a local attacker with special user privileges to cause a denial of service, slowing and eventually stopping the… | ||
| CVE-2021-20177 | Med | 0.22 | 4.4 | 0.00 | May 26, 2021 | A flaw was found in the Linux kernel's implementation of string matching within a packet. A privileged user (with root or CAP_NET_ADMIN) when inserting iptables rules could insert a rule which can panic the system. Kernel before kernel 5.5-rc1 is affected. | ||
| CVE-2020-29371 | Low | 0.22 | 3.3 | 0.01 | Nov 28, 2020 | 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-2021-21781 | Low | 0.21 | 3.3 | 0.01 | Aug 18, 2021 | An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66 and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read the contents of the sigpage, which can leak kernel memory contents. An… | ||
| CVE-2021-38209 | Low | 0.21 | 3.3 | 0.00 | Aug 8, 2021 | net/netfilter/nf_conntrack_standalone.c in the Linux kernel before 5.12.2 allows observation of changes in any net namespace because these changes are leaked into all other net namespaces. This is related to the NF_SYSCTL_CT_MAX, NF_SYSCTL_CT_EXPECT_MAX, and NF_SYSCTL_CT_BUCKETS… | ||
| CVE-2021-38205 | Low | 0.21 | 3.3 | 0.00 | Aug 8, 2021 | drivers/net/ethernet/xilinx/xilinx_emaclite.c in the Linux kernel before 5.13.3 makes it easier for attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM pointer). | ||
| CVE-2021-3655 | Low | 0.21 | 3.3 | 0.00 | Aug 5, 2021 | A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory. | ||
| CVE-2023-2177 | Med | 0.00 | 5.5 | 0.00 | Apr 20, 2023 | A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A local user could use this flaw to crash the system or potentially cause a… | ||
| CVE-2023-1637 | Med | 0.00 | 5.5 | 0.00 | Mar 27, 2023 | A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from suspend-to-RAM. A local user could use this flaw to potentially get… | ||
| CVE-2023-1078 | Hig | 0.00 | 7.8 | 0.00 | Mar 27, 2023 | A flaw was found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user can trigger this with rds_message_put(). Type confusion leads to `struct… | ||
| CVE-2023-1077 | Hig | 0.00 | 7.0 | 0.00 | Mar 27, 2023 | In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a… | ||
| CVE-2023-1076 | Med | 0.00 | 5.5 | 0.00 | Mar 27, 2023 | A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a type confusion in their initialization function. While it will be often correct, as tuntap devices require CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user… | ||
| CVE-2022-23222 | Hig | 0.00 | 7.8 | 0.02 | Jan 14, 2022 | kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of the availability of pointer arithmetic via certain *_OR_NULL pointer types. | ||
| CVE-2021-46283 | Med | 0.00 | 5.5 | 0.00 | Jan 11, 2022 | nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel before 5.12.13 allows local users to cause a denial of service (NULL pointer dereference and general protection fault) because of the missing initialization for nft_set_elem_expr_alloc. A local user can set a… |
