An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free. • https://github.com/sanjana123-cloud/CVE-2019-18683 http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://packetstormsecurity.com/files/155890/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/11/05/1 https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lore.kernel.org/lkml/20191103221719.27118-1-alex.popov%40linux.com https://seclists.org/bugtraq/2020/Jan/10 https://security.net • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

In the Linux kernel before 5.3.4, a reference count usage error in the fib6_rule_suppress() function in the fib6 suppression feature of net/ipv6/fib6_rules.c, when handling the FIB_LOOKUP_NOREF flag, can be exploited by a local attacker to corrupt memory, aka CID-ca7a03c41753. En el kernel de Linux versiones anteriores a 5.3.4, un atacante local puede explotar un error de uso del conteo de referencia en la función fib6_rule_suppress() en la funcionalidad de supresión de fib6 del archivo net/ipv6/fib6_rules.c, cuando maneja el flag FIB_LOOKUP_NOREF, para corromper la memoria , también se conoce como CID-ca7a03c41753. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.4 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ca7a03c4175366a92cee0ccc4fec0038c3266e26 https://github.com/torvalds/linux/commit/ca7a03c4175366a92cee0ccc4fec0038c3266e26 https://launchpad.net/bugs/1847478 https://security.netapp.com/advisory/ntap-20191031-0005 https://usn.ubuntu.com/4161-1 • CWE-772: Missing Release of Resource after Effective Lifetime •
CVSS: 8.8EPSS: 0%CPEs: 13EXPL: 1CVE-2019-17666 – kernel: rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel lacks a certain upper-bound check, leading to a buffer overflow
https://notcve.org/view.php?id=CVE-2019-17666
rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow. En la función rtl_p2p_noa_ie en el archivo drivers/net/wireless/realtek/rtlwifi/ps.c en el kernel de Linux versiones hasta 5.3.6, carece de una cierta comprobación de límite superior, lo que conlleva a un desbordamiento del búfer. A flaw was found in the Linux kernel's implementation of the RealTek wireless drivers WiFi-direct (or WiFi peer-to-peer) driver implementation. When the RealTek wireless networking hardware is configured to accept WiFi-Direct or WiFi P2P connections, an attacker within the wireless network connectivity radio range can exploit a flaw in the WiFi-direct protocol known as "Notice of Absence" by creating specially crafted frames which can then corrupt kernel memory as the upper bounds on the length of the frame is unchecked and supplied by the incoming packet. • https://github.com/uthrasri/CVE-2019-17666 http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00010.html https://access.redhat.com/errata/RHSA-2020:0328 https://access.redhat.com/errata/RHSA-2020:0339 https://access.redhat.com/errata/RHSA-2020:0543 https://access.redhat.com/errata/RHSA-2020:0661 https://access.redhat.com/errata/RHSA-2020:0740 https://arstechnica.com/information-technology/2019/10&# • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2019-17133
In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow. En el kernel de Linux versiones hasta 5.3.2, la función cfg80211_mgd_wext_giwessid en el archivo net/wireless/wext-sme.c no rechaza un SSID IE largo, conllevando a un Desbordamiento de Búfer. A vulnerability was found in the Linux kernel's generic WiFi ESSID handling implementation. The flaw allows a system to join a wireless network where the ESSID is longer than the maximum length of 32 characters, which can cause the system to crash or execute code. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00010.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0374 https://access.redhat.com/errata/RHSA-2020:0375 https://access.redhat.com/errata/RHSA-2020:0543 https://access.redhat.com/errata/RHSA-2020:0592 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable. This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance. Se detectó un problema en la función write_tpt_entry en el archivo drivers/infiniband/hw/cxgb4/mem.c en el kernel de Linux versiones hasta 5.3.2. El controlador cxgb4 está llamando directamente a dma_map_single (una función DMA) desde una variable de la pila. • http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lore.kernel.org/lkml/20191001165611.GA3542072%40kroah.com https://seclists.org/bugtraq/2019/Nov/11 https://usn.ubuntu.com/4208-1 https://usn.ubuntu.com/4210-1 https://usn.ubuntu.com/4211-1 https://usn.ubuntu.com/4211-2 https://usn.ubuntu.com/4226-1 https://www.oracle.com/security-alerts/cp •
