CVSS: 7.8EPSS: 0%CPEs: 20EXPL: 5CVE-2021-33909 – kernel: size_t-to-int conversion vulnerability in the filesystem layer
https://notcve.org/view.php?id=CVE-2021-33909
fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user, aka CID-8cae8cd89f05. Un archivo fs/seq_file.c en el kernel de Linux versiones 3.16 hasta 5.13.x anteriores a 5.13.4, no restringe apropiadamente las asignaciones de búferes seq, conllevando a un desbordamiento de enteros, una escritura fuera de límites y una escalada a root por parte de un usuario no privilegiado, también se conoce como CID-8cae8cd89f05 An out-of-bounds write flaw was found in the Linux kernel's seq_file in the Filesystem layer. This flaw allows a local attacker with a user privilege to gain access to out-of-bound memory, leading to a system crash, leak of internal kernel information and can escalate privileges. The issue results from not validating the size_t-to-int conversion prior to performing operations. The highest threat from this vulnerability is to data integrity, confidentiality and system availability. • https://github.com/Liang2580/CVE-2021-33909 https://github.com/ChrisTheCoolHut/CVE-2021-33909 https://github.com/bbinfosec43/CVE-2021-33909 http://packetstormsecurity.com/files/163621/Sequoia-A-Deep-Root-In-Linuxs-Filesystem-Layer.html http://packetstormsecurity.com/files/163671/Kernel-Live-Patch-Security-Notice-LSN-0079-1.html http://packetstormsecurity.com/files/164155/Kernel-Live-Patch-Security-Notice-LSN-0081-1.html http://packetstormsecurity.com/files/165477/Kernel-Live-Patch-Security-Notice-LSN-0083-1 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-10723
A memory corruption issue was found in DPDK versions 17.05 and above. This flaw is caused by an integer truncation on the index of a payload. Under certain circumstances, the index (a UInt) is copied and truncated into a uint16, which can lead to out of bound indexing and possible memory corruption. Se encontró un problema de corrupción de memoria en DPDK versiones 17.05 y superiores. Este fallo es causado por un truncamiento de enteros en el índice de una carga útil. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00045.html https://bugs.dpdk.org/show_bug.cgi?id=268 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10723 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HRHKFVV4MRWNNJOYQOVP64L4UVWYPEO4 https://usn.ubuntu.com/4362-1 https://www.openwall.com/lists/oss-security/2020/05/18/2 https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020&# • CWE-190: Integer Overflow or Wraparound •

A vulnerability was found in DPDK versions 18.05 and above. A missing check for an integer overflow in vhost_user_set_log_base() could result in a smaller memory map than requested, possibly allowing memory corruption.
