CVE-2023-38427 – Ubuntu Security Notice USN-6466-1
https://notcve.org/view.php?id=CVE-2023-38427
17 Jul 2023 — An issue was discovered in the Linux kernel before 6.3.8. fs/smb/server/smb2pdu.c in ksmbd has an integer underflow and out-of-bounds read in deassemble_neg_contexts. Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel did not properly validate certain data structure fields when parsing lease contexts, leading to an out-of-bounds read vulnerability. A remote attacker could use this to cause a denial of service or possibly expose sensitive information. Quentin Minster discovered that ... • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.3.8 • CWE-125: Out-of-bounds Read CWE-191: Integer Underflow (Wrap or Wraparound) •

17 Jul 2023 — An issue was discovered in the Linux kernel before 6.3.4. fs/ksmbd/smb2pdu.c in ksmbd does not properly check the UserName value because it does not consider the address of security buffer, leading to an out-of-bounds read. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.3.4 • CWE-125: Out-of-bounds Read •

CVE-2023-38429 – Ubuntu Security Notice USN-6339-3
https://notcve.org/view.php?id=CVE-2023-38429
17 Jul 2023 — An issue was discovered in the Linux kernel before 6.3.4. fs/ksmbd/connection.c in ksmbd has an off-by-one error in memory allocation (because of ksmbd_smb2_check_message) that may lead to out-of-bounds access. Zi Fan Tan discovered that the binder IPC implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition existed in the f2fs file system in the Linux ... • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.3.4 • CWE-193: Off-by-one Error •

CVE-2023-38409 – kernel: fbcon: out-of-sync arrays in fbcon_mode_deleted due to wrong con2fb_map assignment
https://notcve.org/view.php?id=CVE-2023-38409
17 Jul 2023 — An issue was discovered in set_con2fb_map in drivers/video/fbdev/core/fbcon.c in the Linux kernel before 6.2.12. Because an assignment occurs only for the first vc, the fbcon_registered_fb and fbcon_display arrays can be desynchronized in fbcon_mode_deleted (the con2fb_map points at the old fb_info). A memory corruption flaw was found in set_con2fb_map in drivers/video/fbdev/core/fbcon.c in the Framebuffer Console in the Linux kernel. This flaw allows a local attacker to crash the system, leading to a denia... • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2.12 • CWE-129: Improper Validation of Array Index CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

CVE-2023-3269 – Distros-[dirtyvma] privilege escalation via non-rcu-protected vma traversal
https://notcve.org/view.php?id=CVE-2023-3269
06 Jul 2023 — A vulnerability exists in the memory management subsystem of the Linux kernel. The lock handling for accessing and updating virtual memory areas (VMAs) is incorrect, leading to use-after-free problems. This issue can be successfully exploited to execute arbitrary kernel code, escalate containers, and gain root privileges. Ruihan Li discovered that the memory management subsystem in the Linux kernel contained a race condition when accessing VMAs in certain conditions, leading to a use-after-free vulnerabilit... • https://github.com/lrh2000/StackRot • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-37454
06 Jul 2023 — An issue was discovered in the Linux kernel through 6.4.2. A crafted UDF filesystem image causes a use-after-free write operation in the udf_put_super and udf_close_lvid functions in fs/udf/super.c. NOTE: the suse.com reference has a different perspective about this. • https://bugzilla.suse.com/show_bug.cgi?id=CVE-2023-37454 • CWE-416: Use After Free •

CVE-2023-37453 – kernel: usb: out-of-bounds read in read_descriptors
https://notcve.org/view.php?id=CVE-2023-37453
06 Jul 2023 — An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds and crash in read_descriptors in drivers/usb/core/sysfs.c. An out-of-bounds read issue was found in the USB subsystem in the Linux kernel. This flaw allows a malicious user to crash the system, resulting in a denial of service condition. Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising speculative execution and branch prediction may allow unauthorised memo... • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1e4c574225cc5a0553115e5eb5787d1474db5b0f • CWE-125: Out-of-bounds Read •
