An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/huge_memory.c. The get_user_pages (aka gup) implementation, when used for a copy-on-write page, does not properly consider the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58. Se detectó un problema en el kernel de Linux versiones anteriores a 5.7.3, relacionado con los archivos mm/gup.c y mm/huge_memory.c. La implementación de la función get_user_pages (también se conoce como gup), cuando se usa para una página copy-on-write, no considera apropiadamente la semántica de las operaciones de lectura y, por lo tanto, puede otorgar acceso de escritura involuntario, también se conoce como CID-17839856fd58 • http://packetstormsecurity.com/files/162117/Kernel-Live-Patch-Security-Notice-LSN-0075-1.html https://bugs.chromium.org/p/project-zero/issues/detail?id=2045 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.7.3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=17839856fd588f4ab6b789f482ed3ffd7c403e1f https://lists.debian.org/debian-lts-announce/2021/06/msg00019.html https://lists.debian.org/debian-lts-announce/2021/06/msg00020.html https://lists.debi • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-863: Incorrect Authorization •
CVSS: 7.2EPSS: 0%CPEs: 39EXPL: 1CVE-2020-15436 – kernel: use-after-free in fs/block_dev.c
https://notcve.org/view.php?id=CVE-2020-15436
Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain privileges or cause a denial of service by leveraging improper access to a certain error field. La vulnerabilidad de tipo use-after-free en el archivo fs/block_dev.c en el kernel de Linux versiones anteriores a 5.8, permite a usuarios locales obtener privilegios o causar una denegación de servicio al aprovechar el acceso inapropiado a un determinado campo de error A use-after-free flaw was observed in blkdev_get(), in fs/block_dev.c after a call to __blkdev_get() fails, and its refcount gets freed/released. This problem may cause a denial of service problem with a special user privilege, and may even lead to a confidentiality issue. • https://lkml.org/lkml/2020/6/7/379 https://security.netapp.com/advisory/ntap-20201218-0002 https://access.redhat.com/security/cve/CVE-2020-15436 https://bugzilla.redhat.com/show_bug.cgi?id=1901168 • CWE-416: Use After Free •

Vulnerability in the Java SE product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 11.0.8 and 15. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00041.html https://lists.debian.org/debian-lts-announce/2020/10/msg00031.html https://security.gentoo.org/glsa/202101-19 https://security.netapp.com/advisory/ntap-20201023-0004 https://www.debian.org/security/2020/dsa-4779 https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020.html https://access.redhat.com/security/cve/CVE-2020-14803 https://bugzilla.redhat.com/show_bug& • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
