CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 1CVE-2019-15239 – kernel: local attacker can trigger multiple use-after-free conditions results in privilege escalation
https://notcve.org/view.php?id=CVE-2019-15239
In the Linux kernel, a certain net/ipv4/tcp_output.c change, which was properly incorporated into 4.16.12, was incorrectly backported to the earlier longterm kernels, introducing a new vulnerability that was potentially more severe than the issue that was intended to be fixed by backporting. Specifically, by adding to a write queue between disconnection and re-connection, a local attacker can trigger multiple use-after-free conditions. This can result in a kernel crash, or potentially in privilege escalation. NOTE: this affects (for example) Linux distributions that use 4.9.x longterm kernels before 4.9.190 or 4.14.x longterm kernels before 4.14.139. En el kernel de Linux, un cierto cambio del archivo net/ipv4/tcp_output.c, que fue incorporado apropiadamente en versión 4.16.12, fue respaldado incorrectamente en los primeros kernels a largo plazo, introduciendo una nueva vulnerabilidad que era potencialmente más severa que el problema que se pretendía solucionar mediante respaldo. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html https://access.redhat.com/errata/RHSA-2019:3978 https://access.redhat.com/errata/RHSA-2019:3979 https://access.redhat.com/errata/RHSA-2020:0027 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7f582b248d0a86bae5788c548d7bb5bca6f7691a https://lore.kernel.org/stable/41a61a2f87691d2bc839f26cdfe6f5ff2f51e472.camel%40decadent.org.uk https: • CWE-416: Use After Free •

An issue was discovered in the Linux kernel before 5.2.6. There is a use-after-free caused by a malicious USB device in the drivers/media/v4l2-core/v4l2-dev.c driver because drivers/media/radio/radio-raremono.c does not properly allocate memory. Se descubrió un problema en el kernel de Linux versiones anteriores a 5.2.6. Se presenta un uso de memoria previamente liberada causado por un dispositivo USB malicioso en el controlador drivers/media/v4l2-core/v4l2-dev.c porque el archivo drivers/media/radio/radio-raremono.c no asigna apropiadamente la memoria. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://www.openwall.com/lists/oss-security/2019/08/20/2 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.2.6 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c666355e60ddb4748ead3bdd983e3f7f2224aaf0 https://lists.debian.org/debian • CWE-416: Use After Free •
