https://notcve.org/view.php?id=CVE-2023-32252
17 May 2023 — A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2_LOGOFF commands. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Linux Kernel. • https://access.redhat.com/security/cve/CVE-2023-32252 • CWE-476: NULL Pointer Dereference •

CVE-2023-2124 – kernel: OOB access in the Linux kernel's XFS subsystem
https://notcve.org/view.php?id=CVE-2023-2124
15 May 2023 — 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. It was discovered that the XFS file system implementation in the Linux kernel did not properly perform metadata validation when mounting certain images. An attacker could use this to specially craft a file system image that, when mounted, could cause a de... • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/fs/xfs/xfs_buf_item_recover.c?h=v6.4-rc1&id=22ed903eee23a5b174e240f1cdfa9acf393a5210 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

CVE-2023-2007 – Linux Kernel DPT I2O Controller Time-Of-Check Time-Of-Use Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2023-2007
13 Apr 2023 — 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. This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target... • https://github.com/torvalds/linux/commit/b04e75a4a8a81887386a0d2dbf605a48e779d2a0 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-667: Improper Locking •

CVE-2023-28464 – Kernel: double free in hci_conn_cleanup of the bluetooth subsystem
https://notcve.org/view.php?id=CVE-2023-28464
31 Mar 2023 — hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux kernel through 6.2.9 has a use-after-free (observed in hci_conn_hash_flush) because of calls to hci_dev_put and hci_conn_put. There is a double free that may lead to privilege escalation. A double-free vulnerability was found in the hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux Kernel. This issue may cause a denial of service or privilege escalation. The SUSE Linux Enterprise 15 SP5 AZURE kernel was updated to receive various security and... • https://lore.kernel.org/lkml/20230309074645.74309-1-wzhmmmmm%40gmail.com • CWE-415: Double Free •

CVE-2023-27537 – Gentoo Linux Security Advisory 202310-12
https://notcve.org/view.php?id=CVE-2023-27537
30 Mar 2023 — A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate "handles". This sharing was introduced without considerations for do this sharing across separate threads but there was no indication of this fact in the documentation. Due to missing mutexes or thread locks, two threads sharing the same HSTS data could end up doing a double-free or use-after-free. Multiple vulnerabilities have been discovered in curl, the worst of which could result in arbitrary code execution. Ver... • https://hackerone.com/reports/1897203 • CWE-415: Double Free •

CVE-2023-1380 – Kernel: a USB-accessible slab-out-of-bounds read in brcmfmac
https://notcve.org/view.php?id=CVE-2023-1380
27 Mar 2023 — A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading to a denial of service. It was discovered that the OverlayFS implementation in the Linux kernel did not properly handle copy up operation in some conditions. A local attacker could possibly use this to gain elevated privileges. It wa... • http://packetstormsecurity.com/files/173087/Kernel-Live-Patch-Security-Notice-LSN-0095-1.html • CWE-125: Out-of-bounds Read •

CVE-2023-1077 – kernel: Type confusion in pick_next_rt_entity()
https://notcve.org/view.php?id=CVE-2023-1077
27 Mar 2023 — In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption. A memory corruption flaw was found in the Linux kernel's scheduler subsystem. This could allow a local user to crash the system or potentially escalate their privileges on the... • https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=7c4a5b89a0b5a57a64b601775b296abf77a9fe97 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

https://notcve.org/view.php?id=CVE-2023-27534
21 Mar 2023 — A path traversal vulnerability exists in curl <8.0.0 SFTP implementation causes the tilde (~) character to be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as the first element to indicate a path relative to the user's home directory. Attackers can exploit this flaw to bypass filtering or execute arbitrary code by crafting a path like /~2/foo while accessing a server with a specific user.

CVE-2023-27535 – curl: FTP too eager connection reuse
https://notcve.org/view.php?id=CVE-2023-27535
21 Mar 2023 — An authentication bypass vulnerability exists in libcurl <8.0.0 in the FTP connection reuse feature that can result in wrong credentials being used during subsequent transfers. Previously created connections are kept in a connection pool for reuse if they match the current setup. However, certain FTP settings such as CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC, and CURLOPT_USE_SSL were not included in the configuration match checks, causing them to match too easily. This could ... • https://hackerone.com/reports/1892780 • CWE-287: Improper Authentication CWE-305: Authentication Bypass by Primary Weakness •
