CVE-2023-39193 |
A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure. Published: October 09, 2023; 2:15:10 PM -0400 |
V4.0:(not available) V3.1: 6.0 MEDIUM V2.0:(not available) |
CVE-2023-39192 |
A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a crash or information disclosure.

CVE-2023-39189 |
A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure. Published: October 09, 2023; 2:15:10 PM -0400 |

CVE-2023-42755 |
A flaw was found in the IPv4 Resource Reservation Protocol (RSVP) classifier in the Linux kernel. The xprt pointer may go beyond the linear part of the skb, leading to an out-of-bounds read in the `rsvp_classify` function. This issue may allow a local user to crash the system and cause a denial of service. Published: October 05, 2023; 3:15:11 PM -0400 |
V4.0:(not available) V3.1: 5.5 MEDIUM V2.0:(not available) |
CVE-2023-42754 |
A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system. Published: October 05, 2023; 3:15:11 PM -0400 |
V4.0:(not available) V3.1: 5.5 MEDIUM V2.0:(not available) |
CVE-2023-39191 |
An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel. Published: October 04, 2023; 3:15:10 PM -0400 |
V4.0:(not available) V3.1: 8.2 HIGH V2.0:(not available) |
CVE-2023-4732 |
A flaw was found in pfn_swap_entry_to_page in memory management subsystem in the Linux Kernel. In this flaw, an attacker with a local user privilege may cause a denial of service problem due to a BUG statement referencing pmd_t x. Published: October 03, 2023; 1:15:09 PM -0400 |
V4.0:(not available) V3.1: 4.7 MEDIUM V2.0:(not available) |
CVE-2023-5345 |
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. Published: October 02, 2023; 11:15:09 PM -0400 |

CVE-2023-44466 |
An issue was discovered in net/ceph/messenger_v2.c in the Linux kernel before 6.4.5. There is an integer signedness error, leading to a buffer overflow and remote code execution via HELLO or one of the AUTH frames. This occurs because of an untrusted length taken from a TCP packet in ceph_decode_32. Published: September 29, 2023; 2:15:11 AM -0400 |
V4.0:(not available) V3.1: 8.8 HIGH V2.0:(not available) |
CVE-2023-42756 |
A flaw was found in the Netfilter subsystem of the Linux kernel. A race condition between IPSET_CMD_ADD and IPSET_CMD_SWAP can lead to a kernel panic due to the invocation of `__ip_set_put` on a wrong `set`. This issue may allow a local user to crash the system. Published: September 28, 2023; 10:15:21 AM -0400 |
V4.0:(not available) V3.1: 4.7 MEDIUM V2.0:(not available) |
CVE-2023-42753 |
An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system. Published: September 25, 2023; 5:15:15 PM -0400 |

CVE-2023-5158 |
A flaw was found in vringh_kiov_advance in drivers/vhost/vringh.c in the host side of a virtio ring in the Linux Kernel. This issue may result in a denial of service from guest to host via zero length descriptor. Published: September 25, 2023; 12:15:15 PM -0400 |
V4.0:(not available) V3.1: 5.5 MEDIUM V2.0:(not available) |
CVE-2020-36766 |
An issue was discovered in the Linux kernel before 5.8.6. drivers/media/cec/core/cec-api.c leaks one byte of kernel memory on specific hardware to unprivileged users, because of directly assigning log_addrs with a hole in the struct. Published: September 18, 2023; 5:15:07 AM -0400 |
V4.0:(not available) V3.1: 3.3 LOW V2.0:(not available) |
CVE-2023-4921 |
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. Published: September 12, 2023; 4:15:10 PM -0400 |

CVE-2023-4623 |
A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control) component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling pointer that can cause a use-after-free. We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f. Published: September 06, 2023; 10:15:12 AM -0400 |

CVE-2023-4622 |
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. Published: September 06, 2023; 10:15:12 AM -0400 |

CVE-2023-4244 |
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage collection, it is possible to underflow the reference counter causing a use-after-free vulnerability. We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8. Published: September 06, 2023; 10:15:11 AM -0400 |

CVE-2023-3777 |
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked whether the chain is bound and the chain's owner rule can also release the objects in certain circumstances. We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8. Published: September 06, 2023; 10:15:10 AM -0400 |

CVE-2023-4611 |
A use-after-free flaw was found in mm/mempolicy.c in the memory management subsystem in the Linux Kernel. This issue is caused by a race between mbind() and VMA-locked page fault, and may allow a local attacker to crash the system or lead to a kernel information leak. Published: August 29, 2023; 6:15:09 PM -0400 |
V4.0:(not available) V3.1: 6.3 MEDIUM V2.0:(not available) |
CVE-2023-4569 |
A memory leak flaw was found in nft_set_catchall_flush in net/netfilter/nf_tables_api.c in the Linux Kernel. This issue may allow a local attacker to cause double-deactivations of catchall elements, which can result in a memory leak. Published: August 28, 2023; 6:15:10 PM -0400 |
