CVSS: 7.5EPSS: 0%CPEs: 7EXPL: 0CVE-2023-32247 – Session setup memory exhaustion denial-of-service vulnerability
https://notcve.org/view.php?id=CVE-2023-32247
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_SESSION_SETUP commands. The issue results from the lack of control of resource consumption. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Se encontró una falla en el ksmbd del kernel de Linux, un servidor SMB de alto rendimiento en el kernel. • https://access.redhat.com/security/cve/CVE-2023-32247 https://bugzilla.redhat.com/show_bug.cgi?id=2219803 https://security.netapp.com/advisory/ntap-20230915-0011 https://www.zerodayinitiative.com/advisories/ZDI-CAN-20478 • CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2023-32252
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 https://bugzilla.redhat.com/show_bug.cgi?id=2219815 https://security.netapp.com/advisory/ntap-20231124-0001 https://www.zerodayinitiative.com/advisories/ZDI-CAN-20590 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2023-2860
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. This vulnerability allows local attackers to disclose sensitive information on affected installations of the Linux Kernel. • https://access.redhat.com/security/cve/CVE-2023-2860 https://bugzilla.redhat.com/show_bug.cgi?id=2218122 https://www.zerodayinitiative.com/advisories/ZDI-CAN-18511 • CWE-125: Out-of-bounds Read •
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 •
