| 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-2021-3655 | 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-2021-22555 | Hig | 0.21 | 8.3 | 0.79 | KEV | Jul 7, 2021 | A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space | |
| CVE-2021-43267 | Cri | 0.05 | 9.8 | 0.58 | Nov 2, 2021 | An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type. | ||
| CVE-2021-33909 | Hig | 0.01 | 7.8 | 0.10 | Jul 20, 2021 | fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user, aka CID-8cae8cd89f05. | ||
| 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… | ||

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-2018-25020 | Hig | 0.00 | 7.8 | 0.01 | Dec 8, 2021 | The BPF subsystem in the Linux kernel before 4.17 mishandles situations with a long jump over an instruction sequence where inner instructions require substantial expansions into multiple BPF instructions, leading to an overflow. This affects kernel/bpf/core.c and… | ||
| CVE-2021-43976 | Med | 0.00 | 4.6 | 0.01 | Nov 17, 2021 | In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic). | ||
| CVE-2021-43975 | Med | 0.00 | 6.7 | 0.01 | Nov 17, 2021 | In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted length value. | ||
| CVE-2021-43389 | Med | 0.00 | 5.5 | 0.01 | Nov 4, 2021 | An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. |
