An issue was discovered in the Linux kernel through 5.3.9. There is a use-after-free when aa_label_parse() fails in aa_audit_rule_init() in security/apparmor/audit.c. Se detectó un problema en el kernel de Linux versiones hasta 5.3.9. Se presenta un uso de la memoria previamente liberada cuando ocurre un fallo de la función aa_label_parse() en la función aa_audit_rule_init() en el archivo security/apparmor/audit.c. • https://lists.debian.org/debian-lts-announce/2020/08/msg00019.html https://lore.kernel.org/patchwork/patch/1142523 https://security.netapp.com/advisory/ntap-20191205-0001 https://support.f5.com/csp/article/K21561554?utm_source=f5support&%3Butm_medium=RSS • CWE-416: Use After Free •
CVSS: 9.8EPSS: 0%CPEs: 34EXPL: 0CVE-2019-18805 – kernel: integer overflow in tcp_ack_update_rtt in net/ipv4/tcp_input.c
https://notcve.org/view.php?id=CVE-2019-18805
An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6. Se detectó un problema en el archivo net/ipv4/sysctl_net_ipv4.c en el kernel de Linux versiones anteriores a 5.0.11. Se presenta un desbordamiento de enteros firmado del archivo net/ipv4/tcp_input.c en la función tcp_ack_update_rtt() cuando el espacio de usuario escribe un entero muy grande en /proc/sys/net/ipv4/tcp_min_rtt_wlen, lo que conlleva a una denegación de servicio o posiblemente a otro impacto no especificado, también se conoce como CID -19fad20d15a6. A flaw was reported in the Linux kernel's TCP subsystem while calculating a packet round trip time, when a sysctl parameter (/proc/sys/net/ipv4/tcp_min_rtt_wlen) is set incorrectly. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00039.html https://access.redhat.com/errata/RHSA-2020:0740 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.11 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=19fad20d15a6494f47f85d869f00b11343ee5c78 https://security.netapp.com/advisory/ntap-20191205-0001 https://access.redhat.com/security/cve/CVE-2019-18805 https: • CWE-190: Integer Overflow or Wraparound •

In the Linux kernel through 5.3.8, f->fmt.sdr.reserved is uninitialized in rcar_drif_g_fmt_sdr_cap in drivers/media/platform/rcar_drif.c, which could cause a memory disclosure problem. En el kernel de Linux versiones hasta 5.3.8, f->fmt.sdr.reserved no se inicializa en la función rcar_drif_g_fmt_sdr_cap en el archivo drivers/media/platform/rcar_drif.c, lo que podría causar un problema de divulgación de memoria. • https://patchwork.linuxtv.org/patch/59542 https://usn.ubuntu.com/4284-1 https://usn.ubuntu.com/4285-1 https://usn.ubuntu.com/4287-1 https://usn.ubuntu.com/4287-2 • CWE-908: Use of Uninitialized Resource •

https://notcve.org/view.php?id=CVE-2019-18683
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 •
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') •
