CVE-2023-33203 |
The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based device. Published: May 18, 2023; 4:15:08 AM -0400 |

CVE-2023-1859 |
A use-after-free flaw was found in xen_9pfs_front_removet in net/9p/trans_xen.c in Xen transport for 9pfs in the Linux Kernel. This flaw could allow a local attacker to crash the system due to a race problem, possibly leading to a kernel information leak. Published: May 17, 2023; 7:15:09 PM -0400 |

CVE-2023-2124 |
An out-of-bounds memory access flaw was found in the Linux kernel’s XFS file system in how a user restores an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or potentially escalate their privileges on the system. Published: May 15, 2023; 6:15:12 PM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0:(not available) |
CVE-2023-2156 |
A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol. This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the system. Published: May 09, 2023; 6:15:10 PM -0400 |
V4.0:(not available) V3.1: 7.5 HIGH V2.0:(not available) |
CVE-2023-2513 |
A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system crash or other undefined behaviors. Published: May 08, 2023; 5:15:11 PM -0400 |
V4.0:(not available) V3.1: 6.7 MEDIUM V2.0:(not available) |
CVE-2023-32233 |
In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled. Published: May 08, 2023; 4:15:20 PM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0:(not available) |
CVE-2023-32269 |
An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order for an attacker to exploit this, the system must have netrom routing configured or the attacker must have the CAP_NET_ADMIN capability. Published: May 05, 2023; 1:15:09 PM -0400 |
V4.0:(not available) V3.1: 6.7 MEDIUM V2.0:(not available) |
CVE-2023-2235 |
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. Published: May 01, 2023; 9:15:44 AM -0400 |

CVE-2023-31436 |
qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write because lmax can exceed QFQ_MIN_LMAX. Published: April 27, 2023; 10:15:09 PM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0:(not available) |
CVE-2023-0458 |
A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents. We recommend upgrading past version 6.1.8 or commit 739790605705ddcf18f21782b9c99ad7d53a8c11 Published: April 26, 2023; 3:15:08 PM -0400 |

CVE-2023-0045 |
The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to the prctl syscall. The patch that added the support for the conditional mitigation via prctl (ib_prctl_set) dates back to the kernel 4.9.176. We recommend upgrading past commit a664ec9158eeddd75121d39c9a0758016097fa96 Published: April 25, 2023; 7:15:09 PM -0400 |

CVE-2023-2007 |
The specific flaw exists within the DPT I2O Controller driver. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the kernel. Published: April 24, 2023; 7:15:18 PM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0:(not available) |
CVE-2023-2019 |
A flaw was found in the Linux kernel's netdevsim device driver, within the scheduling of events. This issue results from the improper management of a reference count. This may allow an attacker to create a denial of service condition on the system. Published: April 24, 2023; 5:15:09 PM -0400 |
V4.0:(not available) V3.1: 4.4 MEDIUM V2.0:(not available) |
CVE-2023-2006 |
A race condition was found in the Linux kernel's RxRPC network protocol, within the processing of RxRPC bundles. This issue results from the lack of proper locking when performing operations on an object. This may allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel. Published: April 24, 2023; 5:15:09 PM -0400 |

CVE-2023-1998 |
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-2023-2194 |
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. Published: April 20, 2023; 5:15:09 PM -0400 |

CVE-2023-2177 |
A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A local user could use this flaw to crash the system or potentially cause a denial of service.
