CVE-2023-1652 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-17 N/A 7.1 HIGH
A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel information leak problem.
CVE-2023-1637 1 Linux 1 Linux Kernel 2026-06-17 N/A 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-2023-1611 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2026-06-17 N/A 6.3 MEDIUM
A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This flaw allows an attacker to crash the system and possibly cause a kernel information lea
CVE-2023-1583 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
A NULL pointer dereference was found in io_file_bitmap_get in io_uring/filetable.c in the io_uring sub-component in the Linux Kernel. When fixed files are unregistered, some context information (file_alloc_{start,end} and alloc_hint) is not cleared. A subsequent request that has auto index selection enabled via IORING_FILE_INDEX_ALLOC can cause a NULL pointer dereference. An unprivileged user can use the flaw to cause a system crash.
CVE-2023-1582 1 Linux 1 Linux Kernel 2026-06-17 N/A 4.7 MEDIUM
A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel. This issue may allow a local attacker with user privilege to cause a denial of service.
CVE-2023-1513 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-06-17 N/A 3.3 LOW
A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an information leak.
CVE-2023-1476 2 Linux, Redhat 6 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 3 more 2026-06-17 N/A 7.0 HIGH
A use-after-free flaw was found in the Linux kernel’s mm/mremap memory address space accounting source code. This issue occurs due to a race condition between rmap walk and mremap, allowing a local user to crash the system or potentially escalate their privileges on the system.
CVE-2023-1390 1 Linux 1 Linux Kernel 2026-06-17 N/A 7.5 HIGH
A remote denial of service vulnerability was found in the Linux kernel’s TIPC kernel module. The while loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system to instantly spike to 100%, causing a denial of service condition.
CVE-2023-1382 1 Linux 1 Linux Kernel 2026-06-17 N/A 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-2023-1295 2 Linux, Netapp 6 Linux Kernel, H300s, H410c and 3 more 2026-06-17 N/A 7.8 HIGH
A time-of-check to time-of-use issue exists in io_uring subsystem's IORING_OP_CLOSE operation in the Linux kernel's versions 5.6 - 5.11 (inclusive), which allows a local user to elevate their privileges to root. Introduced in b5dba59e0cf7e2cc4d3b3b1ac5fe81ddf21959eb, patched in 9eac1904d3364254d622bf2c771c4f85cd435fc2, backported to stable in 788d0824269bef539fe31a785b1517882eafed93.
CVE-2023-1252 1 Linux 1 Linux Kernel 2026-06-17 N/A 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-2023-1249 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
A use-after-free flaw was found in the Linux kernel’s core dump subsystem. This flaw allows a local user to crash the system. Only if patch 390031c94211 ("coredump: Use the vma snapshot in fill_files_note") not applied yet, then kernel could be affected.
CVE-2023-1206 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-06-17 N/A 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-2023-1195 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
A use-after-free flaw was found in reconn_set_ipaddr_from_hostname in fs/cifs/connect.c in the Linux kernel. The issue occurs when it forgets to set the free pointer server->hostname to NULL, leading to an invalid pointer request.
CVE-2023-1194 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2026-06-17 N/A 7.1 HIGH
An out-of-bounds (OOB) memory read flaw was found in parse_lease_state in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. When an attacker sends the CREATE command with a malformed payload to KSMBD, due to a missing check of `NameOffset` in the `parse_lease_state()` function, the `create_context` object can access invalid memory.
CVE-2023-1193 1 Linux 1 Linux Kernel 2026-06-17 N/A 6.5 MEDIUM
A use-after-free flaw was found in setup_async_work in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. This issue could allow an attacker to crash the system by accessing freed work.
CVE-2023-1192 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-17 N/A 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-2023-1118 1 Linux 1 Linux Kernel 2026-06-17 N/A 7.8 HIGH
A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate their privileges on the system.
CVE-2023-1095 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-17 N/A 5.5 MEDIUM
In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list -- the list head is all zeroes, this results in a NULL pointer dereference.
CVE-2023-1079 1 Linux 1 Linux Kernel 2026-06-17 N/A 6.8 MEDIUM
A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.
