CVSS: 6.4EPSS: 0%CPEs: 3EXPL: 0CVE-2023-33203 – kernel: net: qcom/emac: race condition leading to use-after-free in emac_remove()
https://notcve.org/view.php?id=CVE-2023-33203
The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based device. A race condition vulnerability was found in the Linux kernel's Qualcomm EMAC Gigabit Ethernet Controller when the user physically removes the device before cleanup in the emac_remove function. This flaw can eventually result in a use-after-free issue, possibly leading to a system crash or other undefined behaviors. • https://bugzilla.redhat.com/show_bug.cgi?id=2192667 https://bugzilla.suse.com/show_bug.cgi?id=1210685 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2.9 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6b6bc5b8bd2d4ca9e1efa9ae0f98a0b0687ace75 https://access.redhat.com/security/cve/CVE-2023-33203 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-33951
A race condition vulnerability was found in the vmwgfx driver in the Linux kernel. The flaw exists within the handling of GEM objects. The issue results from improper locking when performing operations on an object. This flaw allows a local privileged user to disclose information in the context of the kernel. This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. • https://access.redhat.com/errata/RHSA-2023:6583 https://access.redhat.com/errata/RHSA-2023:6901 https://access.redhat.com/errata/RHSA-2023:7077 https://access.redhat.com/errata/RHSA-2024:1404 https://access.redhat.com/errata/RHSA-2024:4823 https://access.redhat.com/errata/RHSA-2024:4831 https://access.redhat.com/security/cve/CVE-2023-33951 https://bugzilla.redhat.com/show_bug.cgi?id=2218195 https://www.zerodayinitiative.com/advisories/ZDI-CAN-20110 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-667: Improper Locking •
CVSS: 8.2EPSS: 0%CPEs: 5EXPL: 0CVE-2023-33952 – Kernel: vmwgfx: double free within the handling of vmw_buffer_object objects
https://notcve.org/view.php?id=CVE-2023-33952
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 to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of vmw_buffer_object objects. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. • https://access.redhat.com/errata/RHSA-2023:6583 https://access.redhat.com/errata/RHSA-2023:6901 https://access.redhat.com/errata/RHSA-2023:7077 https://access.redhat.com/errata/RHSA-2024:1404 https://access.redhat.com/errata/RHSA-2024:4823 https://access.redhat.com/errata/RHSA-2024:4831 https://access.redhat.com/security/cve/CVE-2023-33952 https://bugzilla.redhat.com/show_bug.cgi?id=2218212 https://www.zerodayinitiative.com/advisories/ZDI-CAN-20292 • CWE-415: Double Free •

An out-of-bounds read vulnerability was found in the SR-IPv6 implementation in the Linux kernel. The flaw exists within the processing of seg6 attributes. The issue results from the improper validation of user-supplied data, which can result in a read past the end of an allocated buffer. This flaw allows a privileged local user to disclose sensitive information on affected installations of the Linux kernel.

CVSS: 6.7EPSS: 0%CPEs: 7EXPL: 0CVE-2023-0459 – Copy_from_user Spectre-V1 Gadget in Linux Kernel
https://notcve.org/view.php?id=CVE-2023-0459
Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec allowing a user to bypass the "access_ok" check and pass a kernel pointer to copy_from_user(). This would allow an attacker to leak information. We recommend upgrading beyond commit 74e19ef0ff8061ef55957c3abd71614ef0f42f47 A vulnerability was found in copy_from_user in 64-bit versions of the Linux kernel. This flaw allows a local attacker to bypass the "access_ok" sanity check and pass a kernel pointer to copy_from_user(), resulting in kernel data leaking. • https://github.com/torvalds/linux/commit/4b842e4e25b12951fa10dedb4bc16bc47e3b850c https://github.com/torvalds/linux/commit/74e19ef0ff8061ef55957c3abd71614ef0f42f47 https://access.redhat.com/security/cve/CVE-2023-0459 https://bugzilla.redhat.com/show_bug.cgi?id=2216383 • CWE-402: Transmission of Private Resources into a New Sphere ('Resource Leak') CWE-763: Release of Invalid Pointer or Reference •
