https://notcve.org/view.php?id=CVE-2023-4010
31 Jul 2023 — A flaw was found in the USB Host Controller Driver framework in the Linux kernel. The usb_giveback_urb function has a logic loophole in its implementation. Due to the inappropriate judgment condition of the goto statement, the function cannot return under the input of a specific malformed descriptor file, so it falls into an endless loop, resulting in a denial of service. • https://access.redhat.com/security/cve/CVE-2023-4010 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

CVE-2023-3773 – Kernel: xfrm: out-of-bounds read of xfrma_mtimer_thresh nlattr
https://notcve.org/view.php?id=CVE-2023-3773
25 Jul 2023 — A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to cause a 4 byte out-of-bounds read of XFRMA_MTIMER_THRESH when parsing netlink attributes, leading to potential leakage of sensitive heap data to userspace. Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising speculative execution and branch prediction may allow unauthorised memory reads via a specula... • https://access.redhat.com/errata/RHSA-2023:6583 • CWE-125: Out-of-bounds Read •

CVE-2023-3772 – Kernel: xfrm: null pointer dereference in xfrm_update_ae_params()

25 Jul 2023 — A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). This issue may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in xfrm_update_ae_params(), leading to a possible kernel crash and denial of service. Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising speculative execution and branch prediction may allow unauthorised memory reads via a speculative side-channel attack.

CVE-2023-3640 – Kernel: x86/mm: a per-cpu entry area leak was identified through the init_cea_offsets function when prefetchnta and prefetcht2 instructions being used for the per-cpu entry area mapping to the user space
https://notcve.org/view.php?id=CVE-2023-3640
24 Jul 2023 — A possible unauthorized memory access flaw was found in the Linux kernel's cpu_entry_area mapping of X86 CPU data to memory, where a user may guess the location of exception stacks or other important data. Based on the previous CVE-2023-0597, the 'Randomize per-cpu entry area' feature was implemented in /arch/x86/mm/cpu_entry_area.c, which works through the init_cea_offsets() function when KASLR is enabled. However, despite this feature, there is still a risk of per-cpu entry area leaks. This issue could al... • https://github.com/pray77/CVE-2023-3640 • CWE-203: Observable Discrepancy •

CVE-2023-3750 – Libvirt: improper locking in virstoragepoolobjlistsearch may lead to denial of service
https://notcve.org/view.php?id=CVE-2023-3750
24 Jul 2023 — A flaw was found in libvirt. The virStoragePoolObjListSearch function does not return a locked pool as expected, resulting in a race condition and denial of service when attempting to lock the same object from another thread. This issue could allow clients connecting to the read-only socket to crash the libvirt daemon. It wad discovered that libvirt incorrectly handled locking when processing certain requests. A local attacker could possibly use this issue to cause libvirt to stop responding or crash, resul... • https://access.redhat.com/errata/RHSA-2023:6409 • CWE-667: Improper Locking •

CVE-2023-3812 – Kernel: tun: bugs for oversize packet when napi frags enabled in tun_napi_alloc_frags
https://notcve.org/view.php?id=CVE-2023-3812
24 Jul 2023 — An out-of-bounds memory access flaw was found in the Linux kernel’s TUN/TAP device driver functionality in how a user generates a malicious (too big) networking packet when napi frags is enabled. This flaw allows a local user to crash or potentially escalate their privileges on the system. An update for kpatch-patch is now available for Red Hat Enterprise Linux 9.
