| The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable. | ||||
| CVE-2024-1086 | 5 Debian, Fedoraproject, Linux and 2 more | 23 Debian Linux, Fedora, Linux Kernel and 20 more | 2025-02-13 | 7.8 High |
| 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 which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660. | ||||
| CVE-2023-6932 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation. A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread. We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1. | ||||
| CVE-2023-6931 | 3 Debian, Linux, Redhat | 6 Debian Linux, Linux Kernel, Enterprise Linux and 3 more | 2025-02-13 | 7.8 High |
| A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation. A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group(). We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b. | ||||
| CVE-2023-6817 | 2 Linux, Redhat | 8 Linux Kernel, Enterprise Linux, Logging and 5 more | 2025-02-13 | 7.8 High |
| 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 commit 317eb9685095678f2c9f5a8189de698c5354316a. | ||||
| CVE-2023-5717 | 2 Linux, Redhat | 5 Linux Kernel, Enterprise Linux, Logging and 2 more | 2025-02-13 | 7.8 High |
| 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 recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06. | ||||
| CVE-2023-4921 | 3 Debian, Linux, Redhat | 10 Debian Linux, Linux Kernel, Enterprise Linux and 7 more | 2025-02-13 | 7.8 High |
| 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(). We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8. | ||||
| CVE-2023-4622 | 3 Debian, Linux, Redhat | 9 Debian Linux, Linux Kernel, Enterprise Linux and 6 more | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local privilege escalation. The unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without locking the queue. Thus there is a race where unix_stream_sendpage() could access an skb locklessly that is being released by garbage collection, resulting in use-after-free. We recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c. | ||||
| CVE-2023-3611 | 3 Debian, Linux, Redhat | 11 Debian Linux, Kernel, Linux Kernel and 8 more | 2025-02-13 | 7.8 High |
| 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 3e337087c3b5805fe0b8a46ba622a962880b5d64. | ||||
| CVE-2023-20593 | 4 Amd, Debian, Redhat and 1 more | 147 Athlon Gold 7220u, Athlon Gold 7220u Firmware, Epyc 7232p and 144 more | 2025-02-13 | 5.5 Medium |
| An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information. | ||||
| CVE-2023-1998 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2025-02-13 | 5.6 Medium |
| The Linux kernel allows userspace processes to enable mitigations by calling prctl with PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection. However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons, which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target injection against which STIBP protects. | ||||
| CVE-2023-1829 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root. We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. | ||||
| CVE-2022-2196 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2025-02-13 | 5.8 Medium |
| A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past commit 2e7eab81425a | ||||
| CVE-2021-33631 | 2 Huawei, Redhat | 5 Openeuler, Enterprise Linux, Logging and 2 more | 2025-02-13 | 5.5 Medium |
| Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows Forced Integer Overflow.This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3, from 5.10.0-60.18.0 before 5.10.0-183.0.0. | ||||
| CVE-2023-35001 | 5 Debian, Fedoraproject, Linux and 2 more | 15 Debian Linux, Fedora, Linux Kernel and 12 more | 2025-02-13 | 7.8 High |
| Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace | ||||
| CVE-2023-3390 | 3 Linux, Netapp, Redhat | 12 Linux Kernel, H300s, H410c and 9 more | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97. | ||||
| CVE-2023-2194 | 3 Fedoraproject, Linux, Redhat | 5 Fedora, Linux Kernel, Enterprise Linux and 2 more | 2025-02-13 | 6.7 Medium |
| An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The userspace "data->block[0]" variable was not capped to a number between 0-255 and was used as the size of a memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to crash the system or potentially achieve code execution. | ||||
