CVE-2024-1086 [HIGH] CWE-416 CVE-2024-1086: 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_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error whi

CVE-2018-5391 [HIGH] CWE-400 CVE-2018-5391: The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of speci The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current

CVE-2017-7558 [HIGH] CWE-125 CVE-2017-7558: A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{, A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket's diagnostic information. As a result, up to 100 bytes of

CVE-2009-2767 [HIGH] CWE-119 CVE-2009-2767: The init_posix_timers function in kernel/posix-timers.c in the Linux kernel before 2.6.31-rc6 allows The init_posix_timers function in kernel/posix-timers.c in the Linux kernel before 2.6.31-rc6 allows local users to cause a denial of service (OOPS) or possibly gain privileges via a CLOCK_MONOTONIC_RAW clock_nanosleep call that triggers a NULL pointer dereference.

It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process.

CVE-2021-34866 [HIGH] CWE-843 CVE-2021-34866: 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 5.14-rc3. 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 prope

It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211944.

CVE-2023-3389 [HIGH] CWE-416 CVE-2023-3389: A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve lo A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59 (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and

CVE-2023-3090 [HIGH] CWE-787 CVE-2023-3090: A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend upgrading past commit 90cbed5247439a966b645

CVE-2023-5717 [HIGH] CWE-787 CVE-2023-5717: A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory locations outside of the allocated buffer. We

CVE-2023-6817 [HIGH] CWE-416 CVE-2023-6817: 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_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free. We recommend upgrading past c

CVE-2023-3611 [HIGH] CWE-787 CVE-2023-3611: An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be explo An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend upgrading past commit 3e337087c3b5805fe0

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-2023-4206 [HIGH] CWE-416 CVE-2023-4206: A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to achieve local privilege escalation. When route4_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_f

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-2023-5345 [HIGH] CWE-416 CVE-2023-5345: A use-after-free vulnerability in the Linux kernel's fs/smb/client component can be exploited to ach A use-after-free vulnerability in the Linux kernel's fs/smb/client component can be exploited to achieve local privilege escalation. In case of an error in smb3_fs_context_parse_param, ctx->password was freed but the field was not set to NULL which could lead to double free. We recommend upgrading past commit e6e43b8aa7cd3c3af686caf0c2e11819a886d705.

CVE-2023-4921 [HIGH] CWE-416 CVE-2023-4921: A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited t A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in agg_dequeue(). W
