CVE-2026-43503 [HIGH] CWE-691 CVE-2026-43503: In the Linux kernel, the following vulnerability has been resolved: net: skbuff: propagate shared-f In the Linux kernel, the following vulnerability has been resolved: net: skbuff: propagate shared-frag marker through frag-transfer helpers Two frag-transfer helpers (__pskb_copy_fclone() and skb_shift()) fail to propagate the SKBFL_SHARED_FRAG bit in skb_shinfo()->flags when moving frags from source to destination. __pskb_copy_fclone() defers the re

CVE-2016-8655 [HIGH] CWE-362 CVE-2016-8655: Race condition in net/packet/af_packet.c in the Linux kernel through 4.8.12 allows local users to ga Race condition in net/packet/af_packet.c in the Linux kernel through 4.8.12 allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging the CAP_NET_RAW capability to change a socket version, related to the packet_set_ring and packet_setsockopt functions.

CVE-2011-2189 [HIGH] CWE-400 CVE-2011-2189: net/core/net_namespace.c in the Linux kernel 2.6.32 and earlier does not properly handle a high rate net/core/net_namespace.c in the Linux kernel 2.6.32 and earlier does not properly handle a high rate of creation and cleanup of network namespaces, which makes it easier for remote attackers to cause a denial of service (memory consumption) via requests to a daemon that requires a separate namespace per connection, as demonstrated by vsftpd.

CVE-2020-12351 [HIGH] CWE-20 CVE-2020-12351: Improper input validation in BlueZ may allow an unauthenticated user to potentially enable escalatio Improper input validation in BlueZ may allow an unauthenticated user to potentially enable escalation of privilege via adjacent access.

CVE-2022-1043 [HIGH] CWE-416 CVE-2022-1043: A flaw was found in the Linux kernel’s io_uring implementation. This flaw allows an attacker with a A flaw was found in the Linux kernel’s io_uring implementation. This flaw allows an attacker with a local account to corrupt system memory, crash the system or escalate privileges.

CVE-2021-43267 [CRITICAL] CWE-1284 CVE-2021-43267: An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Int 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-2023-44466 [HIGH] CWE-120 CVE-2023-44466: An issue was discovered in net/ceph/messenger_v2.c in the Linux kernel before 6.4.5. There is an int An issue was discovered in net/ceph/messenger_v2.c in the Linux kernel before 6.4.5. There is an integer signedness error, leading to a buffer overflow and remote code execution via HELLO or one of the AUTH frames. This occurs because of an untrusted length taken from a TCP packet in ceph_decode_32.

CVE-2017-1000112 [HIGH] CWE-362 CVE-2017-1000112: Linux kernel: Exploitable memory corruption due to UFO to non-UFO path switch. When building a UFO p Linux kernel: Exploitable memory corruption due to UFO to non-UFO path switch. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption. In case UFO packet lengths exceeds MTU, co

CVE-2019-11479 [HIGH] CWE-405 CVE-2019-11479: Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, a

CVE-2016-4997 [HIGH] CWE-264 CVE-2016-4997: The compat IPT_SO_SET_REPLACE and IP6T_SO_SET_REPLACE setsockopt implementations in the netfilter su The compat IPT_SO_SET_REPLACE and IP6T_SO_SET_REPLACE setsockopt implementations in the netfilter subsystem in the Linux kernel before 4.6.3 allow local users to gain privileges or cause a denial of service (memory corruption) by leveraging in-container root access to provide a crafted offset value that triggers an unintended decrement.
