CVSS: 7.8EPSS: 2%CPEs: 42EXPL: 0CVE-2019-15538 – kernel: denial of service in in xfs_setattr_nonsize in fs/xfs/xfs_iops.c
https://notcve.org/view.php?id=CVE-2019-15538
An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS. Se descubrió un problema en xfs_setattr_nonsize en fs / xfs / xfs_iops.c en el kernel de Linux a través de 5.2.9. XFS se bloquea parcialmente cuando falla un chgrp debido a que no se encuentra en la cuota de disco. xfs_setattr_nonsize no puede desbloquear el ILOCK después de que la llamada xfs_qm_vop_chown_reserve falla. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1fb254aa983bf190cfd685d40c64a480a9bafaee https://github.com/torvalds/linux/commit/1fb254aa983bf190cfd685d40c64a480a9bafaee https://lists.debian.org/debian-lts-announce/2019/09/msg00014.html https://lists.debian.org/debian-lts-announce/2019/09/msg00015.html https://lists.fedoraproject.org/archives& • CWE-400: Uncontrolled Resource Consumption •
CVSS: 10.0EPSS: 0%CPEs: 12EXPL: 0CVE-2019-15505 – kernel: out of bounds read in drivers/media/usb/dvb-usb/technisat-usb2.c
https://notcve.org/view.php?id=CVE-2019-15505
drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via crafted USB device traffic (which may be remote via usbip or usbredir). drivers/media/usb/dvb-usb/technisat-usb2.c en el kernel de Linux hasta la versión 5.2.9 tiene una lectura fuera de los límites a través del tráfico de dispositivos USB diseñado (que puede ser remoto a través de usbip o usbredir). An out-of-bounds read flaw was found in the DVB USB subsystem of the Linux kernel. There was no boundary check applied to the array in struct technisat_usb2_state state->buf until the 0xff byte is encountered. If the byte is not encountered within the limit, an exposure of kernel data structure occurs. Data confidentiality and system availability are the highest threats with this vulnerability. • http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://git.linuxtv.org/media_tree.git/commit/?id=0c4df39e504bf925ab666132ac3c98d6cbbe380b https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/O3RUDQJXRJQVGHCGR4YZWTQ3ECBI7TXH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedorapro • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2019-15099
drivers/net/wireless/ath/ath10k/usb.c in the Linux kernel through 5.2.8 has a NULL pointer dereference via an incomplete address in an endpoint descriptor. El archivo drivers/net/wireless/ath/ath10k/usb.c en el kernel de Linux versiones hasta 5.2.8, presenta una desreferencia del puntero NULL por medio de una dirección incompleta en un descriptor de endpoint. A null pointer dereference flaw was discovered in the Linux kernel's implementation of the ath10k USB device driver. The vulnerability requires the attacker to plug in a specially crafted hardware device that present endpoint descriptors that normal ath10k devices do not recognize. System availability is the highest threat with this vulnerability. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html https://lore.kernel.org/linux-wireless/20190804003101.11541-1-benquike%40gmail.com/T/#u https://security.netapp.com/advisory/ntap-20190905-0002 https://support.f5.com/csp/article/K76295179 https://support.f5.com/csp/article/K76295179?utm_source=f5support&%3Butm_medium=RSS https://usn.ubuntu.com/4258-1 https://usn.ubuntu.com/4284-1 https://usn.ubuntu.com/4287-1 https://usn.ubuntu.com/4287-2 http • CWE-20: Improper Input Validation CWE-476: NULL Pointer Dereference •

A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before 4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware could use this flaw to issue a specially crafted ioctl function call and cause the system to crash.

https://notcve.org/view.php?id=CVE-2014-0069
The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer. La función cifs_iovec_write en fs/cifs/file.c en el kernel de Linux hasta 3.13.5 no maneja debidamente operaciones de escritura no en caché que copian menos bytes de los solicitados, lo que permite a usuarios locales obtener información sensible de la memoria del kernel, causar una denegación de servicio (corrupción de memoria y caída del sistema) o posiblemente ganar privilegios a través de una llamada al sistema writev con un puntero manipulado. • http://article.gmane.org/gmane.linux.kernel.cifs/9401 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=5d81de8e8667da7135d3a32a964087c0faf5483f http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00026.html http://rhn.redhat.com/errata/RHSA-2014-0328.html http://www.openwall.com/lists/oss-security/2014/02/17/4 http://www.securityfocus.com/bid/65588 https://bugzilla.redhat.com/show_bug.cgi?id=1064253 https://github.com/torvalds/linux/comm • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
