| CVE-2022-32296 | Low | 0.00 | 3.3 | 0.00 | Jun 5, 2022 | The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are used. This occurs because of use of Algorithm 4 ("Double-Hash Port Selection Algorithm") of RFC 6056. | ||
| CVE-2021-45868 | Med | 0.00 | 5.5 | 0.01 | Mar 18, 2022 | In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file. | ||
| CVE-2021-3744 | Med | 0.00 | 5.5 | 0.01 | Mar 4, 2022 | A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808. | ||

This flaw allows unprivileged local users to escalate their… | ||
| CVE-2021-3753 | Med | 0.00 | 4.7 | 0.00 | Feb 16, 2022 | A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl (KDSETMDE). The highest threat from this vulnerability is to data… | ||
| CVE-2021-44879 | Med | 0.00 | 5.5 | 0.01 | Feb 14, 2022 | In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered, leading to a move_data_page NULL pointer dereference. | ||
| CVE-2021-45402 | Med | 0.00 | 5.5 | 0.00 | Feb 11, 2022 | The check_alu_op() function in kernel/bpf/verifier.c in the Linux kernel through v5.16-rc5 did not properly update bounds while handling the mov32 instruction, which allows local users to obtain potentially sensitive address information, aka a "pointer leak." | ||
| CVE-2021-45485 | Hig | 0.00 | 7.5 | 0.04 | Dec 25, 2021 | In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. | ||
| CVE-2021-44733 | Hig | 0.00 | 7.0 | 0.01 | Dec 22, 2021 | A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11. This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. | ||
| 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-2021-43057 | Hig | 0.00 | 7.8 | 0.00 | Oct 28, 2021 | An issue was discovered in the Linux kernel before 5.14.8. A use-after-free in selinux_ptrace_traceme (aka the SELinux handler for PTRACE_TRACEME) could be used by local attackers to cause memory corruption and escalate privileges, aka CID-a3727a8bac0a. This occurs because of an… | ||
| CVE-2021-42327 | Med | 0.00 | 6.7 | 0.01 | Oct 21, 2021 | dp_link_settings_write in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within… | ||
| CVE-2021-42252 | Hig | 0.00 | 7.8 | 0.00 | Oct 11, 2021 | An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileges, aka… | ||
| CVE-2021-42008 | Hig | 0.00 | 7.8 | 0.01 | Oct 5, 2021 | The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access. | ||
| CVE-2021-41864 | Hig | 0.00 | 7.8 | 0.00 | Oct 2, 2021 | prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write. |
