CVE-2023-34256 – Ubuntu Security Notice USN-6701-3
https://notcve.org/view.php?id=CVE-2023-34256
31 May 2023 — An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against attackers with the stated "When modifying the block device while it is mounted by the filesystem" access. Se ha descubierto un problema en el kernel de Linux en las versiones anteriores a 6.3.3. Hay una lectur... • https://bugzilla.suse.com/show_bug.cgi?id=1211895 • CWE-125: Out-of-bounds Read •

CVE-2023-32254 – Tree connection race condition remote code execution vulnerability
https://notcve.org/view.php?id=CVE-2023-32254
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 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. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Linux Kernel. • https://access.redhat.com/security/cve/CVE-2023-32254 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

CVE-2023-33952 – Kernel: vmwgfx: double free within the handling of vmw_buffer_object objects
https://notcve.org/view.php?id=CVE-2023-33952
17 May 2023 — A double-free vulnerability was found in handling vmw_buffer_object objects in the vmwgfx driver in the Linux kernel. This issue occurs due to the lack of validating the existence of an object prior to performing further free operations on the object, which may allow a local privileged user to escalate privileges and execute code in the context of the kernel. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability ... • https://access.redhat.com/errata/RHSA-2023:6583 • CWE-415: Double Free •
