An issue was discovered in xfs_agf_verify in fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through 5.6.10. Attackers may trigger a sync of excessive duration via an XFS v5 image with crafted metadata, aka CID-d0c7feaf8767. Se detectó un problema en la función xfs_agf_verify en el archivo fs/xfs/libxfs/xfs_alloc.c en el kernel de Linux versiones hasta 5.6.10. Los atacantes pueden desencadenar una sincronización de duración excesiva por medio de una imagen XFS v5 con metadatos diseñados, también se conoce como CID-d0c7feaf8767. A flaw was discovered in the XFS source in the Linux kernel. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d0c7feaf87678371c2c09b3709400be416b2dc62 https://github.com/torvalds/linux/commit/d0c7feaf87678371c2c09b3709400be416b2dc62 https://lists.debian.org/debian-lts-announce/2020/08/msg00019.html https://lists.debian.org/debian-lts-announce/2020/10/msg00032.html https://lists.debian.org/debian-lts-announce/2020/10/msg00034.html https://lists.fedoraproject.org/archives/li • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

https://notcve.org/view.php?id=CVE-2020-12654
An issue was found in Linux kernel before 5.5.4. mwifiex_ret_wmm_get_status() in drivers/net/wireless/marvell/mwifiex/wmm.c allows a remote AP to trigger a heap-based buffer overflow because of an incorrect memcpy, aka CID-3a9b153c5591. Se detectó un problema en el kernel de Linux versiones anteriores a 5.5.4. En la función mwifiex_ret_wmm_get_status() en el archivo drivers/net/wireless/marvell/mwifiex/wmm.c permite a un AP remoto desencadenar un desbordamiento del búfer en la región heap de la memoria debido a una memcpy incorrecta, también se conoce como CID-3a9b153c5591. A flaw was found in the Linux kernel. The Marvell mwifiex driver allows a remote WiFi access point to trigger a heap-based memory buffer overflow due to an incorrect memcpy operation. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://www.openwall.com/lists/oss-security/2020/05/08/2 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.5.4 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3a9b153c5591548612c3955c9600a98150c81875 https://github.com/torvalds/linux/commit/3a9b153c5591548612c3955c9600a98150c81875 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

An issue was found in Linux kernel before 5.5.4. The mwifiex_cmd_append_vsie_tlv() function in drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea. Se detectó un problema en el kernel de Linux versiones anteriores a 5.5.4. La función mwifiex_cmd_append_vsie_tlv() en el archivo drivers/net/wireless/marvell/mwifiex/scan.c permite a usuarios locales alcanzar privilegios o causar una denegación de servicio debido a una memcpy incorrecta y al desbordamiento del búfer, también se conoce como CID-b70261a288ea.

The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a "double fetch" vulnerability, aka CID-28d76df18f0a. NOTE: the vendor states "The security impact of this bug is not as bad as it could have been because these operations are all privileged and root already has enormous destructive power." La función __mptctl_ioctl en el archivo drivers/message/fusion/mptctl.c en el kernel de Linux versiones anteriores a 5.4.14, permite a usuarios locales mantener un bloqueo incorrecto durante la operación ioctl y desencadenar una condición de carrera, es decir, una vulnerabilidad de "double fetch", también se conoce como CID-28d76df18f0a. NOTA: el suplidor afirma "El impacto de seguridad de este bug no es tan malo como podría haber sido debido a que estas operaciones son privilegiadas y la root ya posee un enorme poder destructivo. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.14 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=28d76df18f0ad5bcf5fa48510b225f0ed262a99b https://github.com/torvalds/linux/commit/28d76df18f0ad5bcf5fa48510b225f0ed262a99b https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debian.org/debian-lts- • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 4.7EPSS: 0%CPEs: 5EXPL: 0CVE-2020-12114 – kernel: DoS by corrupting mountpoint reference counter
https://notcve.org/view.php?id=CVE-2020-12114
A pivot_root race condition in fs/namespace.c in the Linux kernel 4.4.x before 4.4.221, 4.9.x before 4.9.221, 4.14.x before 4.14.178, 4.19.x before 4.19.119, and 5.x before 5.3 allows local users to cause a denial of service (panic) by corrupting a mountpoint reference counter. Una condición de carrera en la función pivot_root en el archivo fs/namespace.c en el kernel de Linux versiones 4.4.x anteriores a la versión 4.4.221, versiones 4.9.x anteriores a la versión 4.9.221, versiones 4.14.x anteriores a la versión 4.14.178, versiones 4.19.x anteriores a 4.19.119, y versiones 5.x anteriores a la versión 5.3, permite a usuarios locales causar una denegación de servicio (pánico) al corromper un contador de referencia de punto de montaje. A flaw was found in the Linux kernel’s implementation of the pivot_root syscall. This flaw allows a local privileged user (root outside or root inside a privileged container) to exploit a race condition to manipulate the reference count of the root filesystem. To be able to abuse this flaw, the process or user calling pivot_root must have advanced permissions. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://packetstormsecurity.com/files/159565/Kernel-Live-Patch-Security-Notice-LSN-0072-1.html http://www.openwall.com/lists/oss-security/2020/05/04/2 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://security.netapp.com/advisory/ntap-20200608-0001 https: • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-400: Uncontrolled Resource Consumption •
