Linux Kernel vulnerabilities

CVE-2024-1085 [HIGH] CWE-416 CVE-2024-1085: A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_setelem_catchall_deactivate() function checks whether the catch-all set element is active in the current generation instead of the next generation before freeing it, but only flags it inactive in the next g

CVE-2023-3610 [HIGH] CWE-416 CVE-2023-3610: A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend upgrading past commit 4bedf9eee016286

CVE-2017-2634 [HIGH] CWE-476 CVE-2017-2634: It was found that the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation befo It was found that the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation before 2.6.22.17 used the IPv4-only inet_sk_rebuild_header() function for both IPv4 and IPv6 DCCP connections, which could result in memory corruptions. A remote attacker could use this flaw to crash the system.

CVE-2022-0742 [HIGH] CWE-275 CVE-2022-0742: Memory leak in icmp6 implementation in Linux Kernel 5.13+ allows a remote attacker to DoS a host by Memory leak in icmp6 implementation in Linux Kernel 5.13+ allows a remote attacker to DoS a host by making it go out-of-memory via icmp6 packets of type 130 or 131. We recommend upgrading past commit 2d3916f3189172d5c69d33065c3c21119fe539fc.

CVE-2021-3444 [HIGH] CWE-681 CVE-2021-3444: The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation w The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0. A local attacker with the ability to load bpf programs could use this gain out-of-bounds reads in kernel memory leading to information disclosure (kernel memory), and possibly out-of-bounds writes that could pote

CVE-2023-3776 [HIGH] CWE-416 CVE-2023-3776: A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it t

CVE-2023-3609 [HIGH] CWE-416 CVE-2023-3609: A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited t A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set i

CVE-2023-3777 [HIGH] CWE-416 CVE-2023-3777: A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain circumstances. We recommend upgrading past commit 6

CVE-2023-6111 [HIGH] CWE-416 CVE-2023-6111: A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The function nft_trans_gc_catchall did not remove the catchall set element from the catchall_list when the argument sync is true, making it possible to free a catchall set element many times. We recommend upgradin

CVE-2023-4207 [HIGH] CWE-416 CVE-2023-4207: A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation. When fw_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter()

CVE-2023-4208 [HIGH] CWE-416 CVE-2023-4208: A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited t A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. When u32_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter

CVE-2023-4015 [HIGH] CWE-416 CVE-2023-4015: A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. On an error when building a nftables rule, deactivating immediate expressions in nft_immediate_deactivate() can lead unbinding the chain and objects be deactivated but later used. We recommend upgrading past commi

CVE-2023-4623 [HIGH] CWE-416 CVE-2023-4623: A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control) component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remov

CVE-2022-3636 [HIGH] CWE-119 CVE-2022-3636: A vulnerability was identified in Linux Kernel 33fc42de33278b2b3ec6f3390512987bc29a62b7. This affect A vulnerability was identified in Linux Kernel 33fc42de33278b2b3ec6f3390512987bc29a62b7. This affects the function __mtk_ppe_check_skb of the file drivers/net/ethernet/mediatek/mtk_ppe.c of the component Ethernet Handler. Such manipulation leads to use after free. The name of the patch is 17a5f6a78dc7b8db385de346092d7d9f9dc24df6. It is best practice to

CVE-2021-31440 [HIGH] CWE-682 CVE-2021-31440: This vulnerability allows local attackers to escalate privileges on affected installations of Linux This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.11.15. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper

CVE-2024-0565 [HIGH] CWE-191 CVE-2024-0565: An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy length, leading to a denial of service.

CVE-2018-10853 [HIGH] CWE-250 CVE-2018-10853: A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as sg A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges inside guest.
