CVSS: 7.8EPSS: 1%CPEs: 8EXPL: 0CVE-2019-15916 – kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c leads to denial of service
https://notcve.org/view.php?id=CVE-2019-15916
An issue was discovered in the Linux kernel before 5.0.1. There is a memory leak in register_queue_kobjects() in net/core/net-sysfs.c, which will cause denial of service. Se descubrió un problema en el kernel de Linux versiones anteriores a 5.0.1. Se presenta una pérdida de memoria en la función register_queue_kobjects() en el archivo net/core/net-sysfs.c, lo que causará una denegación de servicio. A flaw that allowed an attacker to leak kernel memory was found in the network subsystem where an attacker with permissions to create tun/tap devices can create a denial of service and panic the system. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://access.redhat.com/errata/RHSA-2020:0740 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=895a5e96dbd6386c8e78e5b78e067dcc67b7f0ab https://security.netapp.com/advisory/ntap-20191004-0001 https://support.f5.com/csp/art • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •

A backporting error was discovered in the Linux stable/longterm kernel 4.4.x through 4.4.190, 4.9.x through 4.9.190, 4.14.x through 4.14.141, 4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the upstream "x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()" commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped. Se descubiró un error de backporting en el kernel de Linux estable/a largo plazo en sus versiones 4.4.x hasta 4.4.190, versiones 4.9.x hasta 4.9.190, versiones 4.14.x hasta 4.14.141, versiones 4.19.x hasta 4.19.69 y versiones 5.2.x hasta 5.2 .11. El uso incorrecto del commit "x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()" aguas arriba reintrodujo la vulnerabilidad Spectre que se pretendía eliminar. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html https://grsecurity.net/teardown_of_a_failed_linux_lts_spectre_fix.php https://lists.debian.org/debian-lts-announce/2019/10/msg00000.html https://seclists.org/bugtraq/2019/Sep/41 https://security.netapp.com/advisory/ntap-20191004-0001 https://usn.ubuntu.com/4157-1 https://usn.ubuntu.com/4157-2 https://usn.ubuntu.com/4162-1 http • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service. En el kernel de Linux versiones anteriores a 5.1.13, se presenta una pérdida de memoria en la biblioteca drivers/scsi/libsas/sas_expander.c cuando no se detecta el expansor SAS. Esto provocará un BUG y una denegación de servicio.

https://notcve.org/view.php?id=CVE-2019-15666
An issue was discovered in the Linux kernel before 5.0.19. There is an out-of-bounds array access in __xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandles directory validation. Se descubrió un fallo en el núcleo de Linux en versiones anteriores a 5.0.19. Hay un acceso a array fuera de límites en __xfrm_policy_unlink, lo que causará una denegación del servicio, ya que verify_newpolicy_info en net/xfrm/xfrm_user.c gestiona mal la validación de directorios.

CVSS: 7.8EPSS: 1%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 •
