  1. CVE-2023-3610

    High · CVSS 7.8EPSS 0.25%Fix available

    Use-after-free in Linux kernel's netfilter: nf_tables component

    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 4bedf9eee016286c835e3d8fa981ddece5338795.

  2. CVE-2023-3609

    High · CVSS 7.8EPSS 0.49%Fix available

    Use-after-free in Linux kernel's net/sched: cls_u32 component

    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 it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.

    Critical · CVSS 9.1EPSS 1.16%Fix available

    CVE-2023-38431

    An issue was discovered in the Linux kernel before 6.3.8. fs/smb/server/connection.c in ksmbd does not validate the relationship between the NetBIOS header's length field and the SMB header sizes, via pdu_size in ksmbd_conn_handler_loop, leading to an out-of-bounds read.

  4. CVE-2023-21400

    Medium · CVSS 6.7EPSS 0.26%Fix available

    CVE-2023-21400

    In multiple functions of io_uring.c, there is a possible kernel memory corruption due to improper locking. This could lead to local escalation of privilege in the kernel with System execution privileges needed. User interaction is not needed for exploitation.

  5. CVE-2023-32254

    Critical · CVSS 9.8EPSS 2.91%Fix available

    Tree connection race condition remote code execution vulnerability

    A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_TREE_DISCONNECT commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel.

  6. CVE-2023-32250

    Critical · CVSS 9EPSS 2.59%Fix available

    Session race condition remote code execution vulnerability

    A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_SESSION_SETUP commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel.

  7. CVE-2023-1206

    High · CVSS 8.7EPSS 0.63%Public exploitFix available

    CVE-2023-1206

    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%.

  8. CVE-2023-3212

    Medium · CVSS 4.4EPSS 0.28%Fix available

    CVE-2023-3212

    A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic.
