| A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation. The perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability. We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2. | ||||

| CVE-2023-1998 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2024-08-02 | 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-2023-1838 | 3 Linux, Netapp, Redhat | 9 Linux Kernel, H300s, H410c and 6 more | 2024-08-02 | 7.1 High |
| A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in virtio network subcomponent in the Linux kernel due to a double fget. This flaw could allow a local attacker to crash the system, and could even lead to a kernel information leak problem. | ||||
| CVE-2023-1855 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2024-08-02 | 6.3 Medium |
| A use-after-free flaw was found in xgene_hwmon_remove in drivers/hwmon/xgene-hwmon.c in the Hardware Monitoring Linux Kernel Driver (xgene-hwmon). This flaw could allow a local attacker to crash the system due to a race problem. This vulnerability could even lead to a kernel information leak problem. | ||||
| CVE-2023-1829 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-08-02 | 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-2023-1668 | 3 Cloudbase, Debian, Redhat | 8 Open Vswitch, Debian Linux, Enterprise Linux and 5 more | 2024-08-02 | 8.2 High |
| A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow. | ||||
| CVE-2023-1637 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-08-02 | 5.5 Medium |
| A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of the CPU similar to the speculative execution behavior kind of attacks. | ||||
| CVE-2023-1382 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2024-08-02 | 4.7 Medium |
| A data race flaw was found in the Linux kernel, between where con is allocated and con->sock is set. This issue leads to a NULL pointer dereference when accessing con->sock->sk in net/tipc/topsrv.c in the tipc protocol in the Linux kernel. | ||||
| CVE-2023-1252 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2024-08-02 | 7.8 High |
| A use-after-free flaw was found in the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch 9a2544037600 ("ovl: fix use after free in struct ovl_aio_req") not applied yet, the kernel could be affected. | ||||
| CVE-2023-1281 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-08-02 | 7.8 High |
| Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. | ||||
| CVE-2023-1206 | 3 Fedoraproject, Linux, Redhat | 5 Fedora, Linux Kernel, Enterprise Linux and 2 more | 2024-08-02 | 5.7 Medium |
| A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%. | ||||
| CVE-2023-1192 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-08-02 | 6.5 Medium |
| A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service. | ||||
| CVE-2023-1195 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2024-08-02 | 5.5 Medium |
