CVE-2023-26074 – Shannon Baseband NrmmMsgCodec Access Category Definitions Heap Buffer Overflow
https://notcve.org/view.php?id=CVE-2023-26074
An issue was discovered in Samsung Mobile Chipset and Baseband Modem Chipset for Exynos 850, Exynos 980, Exynos 1080, Exynos 1280, Exynos 2200, Exynos Modem 5123, Exynos Modem 5300, and Exynos Auto T5123.. A heap-based buffer overflow in the 5G MM message codec can occur due to insufficient parameter validation when decoding operator-defined access category definitions. There is a heap buffer overflow in Shannon Baseband, inside the 5G MM protocol implementation (NrmmMsgCodec as it is called in Shannon according to debug strings), specifically when handling the Operator-defined access category definitions message (IEI = 0x76). • http://packetstormsecurity.com/files/171383/Shannon-Baseband-NrmmMsgCodec-Access-Category-Definitions-Heap-Buffer-Overflow.html https://bugs.chromium.org/p/project-zero/issues/detail?id=2397 https://googleprojectzero.blogspot.com/2023/03/multiple-internet-to-baseband-remote-rce.html https://semiconductor.samsung.com/processor/mobile-processor https://semiconductor.samsung.com/processor/modem https://semiconductor.samsung.com/support/quality-support/product-security-updates • CWE-787: Out-of-bounds Write •

CVE-2022-42703 – kernel: use-after-free related to leaf anon_vma double reuse
https://notcve.org/view.php?id=CVE-2022-42703
mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse. El archivo mm/rmap.c en el kernel de Linux versiones anteriores a 5.19.7, presenta un uso de memoria previamente liberada relacionado con un doble reúso de la hoja anon_vma A memory leak flaw with use-after-free capability was found in the Linux kernel. The VMA mm/rmap.c functionality in the is_mergeable_anon_vma() function continuously forks, using memory operations to trigger an incorrect reuse of leaf anon_vma. This issue allows a local attacker to crash the system. • https://bugs.chromium.org/p/project-zero/issues/detail?... id=2555283eb40df89945557273121e9393ef9b542b https://github.com/torvalds/linux/commit/2555283eb40df89945557273121e9393ef9b542b https://googleprojectzero.blogspot.com/2022/12/exploiting-CVE-2022-42703-bringing-back-the-stack-attack.html https://access.redhat.com/security/cve/CVE-2022-42703 https://bugzilla.redhat.com/show_bug.cgi? • CWE-416: Use After Free •
CVE-2022-34169 – Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious XSLT stylesheets
https://notcve.org/view.php?id=CVE-2022-34169
The Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious XSLT stylesheets. This can be used to corrupt Java class files generated by the internal XSLTC compiler and execute arbitrary Java bytecode. Users are recommended to update to version 2.7.3 or later. Note: Java runtimes (such as OpenJDK) include repackaged copies of Xalan. La biblioteca Apache Xalan Java XSLT es vulnerable a un problema de truncamiento de enteros cuando procesa hojas de estilo XSLT maliciosas. • https://github.com/bor8/CVE-2022-34169 http://packetstormsecurity.com/files/168186/Xalan-J-XSLTC-Integer-Truncation.html http://www.openwall.com/lists/oss-security/2022/07/19/5 http://www.openwall.com/lists/oss-security/2022/07/19/6 http://www.openwall.com/lists/oss-security/2022/07/20/2 http://www.openwall.com/lists/oss-security/2022/07/20/3 http://www.openwall.com/lists/oss-security/2022/10/18/2 http://www.openwall.com/lists/oss-security/2022/11/ • CWE-192: Integer Coercion Error CWE-681: Incorrect Conversion between Numeric Types •
CVE-2022-26362 – Xen TLB Flush Bypass
https://notcve.org/view.php?id=CVE-2022-26362
x86 pv: Race condition in typeref acquisition Xen maintains a type reference count for pages, in addition to a regular reference count. This scheme is used to maintain invariants required for Xen's safety, e.g. PV guests may not have direct writeable access to pagetables; updates need auditing by Xen. Unfortunately, the logic for acquiring a type reference has a race condition, whereby a safely TLB flush is issued too early and creates a window where the guest can re-establish the read/write mapping before writeability is prohibited. x86 pv: Una condición de carrera en la adquisición de typeref Xen mantiene un recuento de referencias de tipo para las páginas, además de un recuento de referencias regular. Este esquema es usado para mantener invariantes requeridos para la seguridad de Xen, por ejemplo, los huéspedes PV no pueden tener acceso directo de escritura a las tablas de páginas; las actualizaciones necesitan ser auditadas por Xen. • http://packetstormsecurity.com/files/167718/Xen-TLB-Flush-Bypass.html http://www.openwall.com/lists/oss-security/2022/06/09/3 http://xenbits.xen.org/xsa/advisory-401.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OH65U6FTTB5MLH5A6Q3TW7KVCGOG4MYI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RKRXZ4LHGCGMOG24ZCEJNY6R2BTS4S2Q https://security.gentoo.org/glsa/202208-23 https://www.debian.org/security/2022/dsa-5184 http • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
