CVSS: 10.0EPSS: 0%CPEs: 7EXPL: 0CVE-2021-38578 – edk2: integer underflow in SmmEntryPoint function leads to potential SMM privilege escalation
https://notcve.org/view.php?id=CVE-2021-38578
Existing CommBuffer checks in SmmEntryPoint will not catch underflow when computing BufferSize. Unas comprobaciones existentes de CommBuffer en SmmEntryPoint no detectan el desbordamiento cuando es calculado BufferSize A flaw was found in edk2. A integer underflow in the SmmEntryPoint function leads to a write into the SMM region allowing a local attacker with administration privileges on the system to execute code within the SMM privileged context. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://bugzilla.tianocore.org/show_bug.cgi?id=3387 https://www.insyde.com/security-pledge/SA-2023024 https://access.redhat.com/security/cve/CVE-2021-38578 https://bugzilla.redhat.com/show_bug.cgi?id=1960321 • CWE-124: Buffer Underwrite ('Buffer Underflow') CWE-787: Out-of-bounds Write •

NetworkPkg/IScsiDxe has remotely exploitable buffer overflows. NetworkPkg/IScsiDxe presenta unos desbordamientos de búfer explotables de forma remota A flaw was found in edk2. Missing checks in the IScsiHexToBin function in NetworkPkg/IScsiDxe lead to a buffer overflow allowing a remote attacker, who can inject himself in the communication between edk2 and the iSCSI target, to write arbitrary data to any address in the edk2 firmware and potentially execute code. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://bugzilla.tianocore.org/show_bug.cgi?id=3356 https://www.insyde.com/security-pledge/SA-2023025 https://access.redhat.com/security/cve/CVE-2021-38575 https://bugzilla.redhat.com/show_bug.cgi?id=1956284 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-124: Buffer Underwrite ('Buffer Underflow') •
