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') •

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 •

usb_sg_cancel in drivers/usb/core/message.c in the Linux kernel before 5.6.8 has a use-after-free because a transfer occurs without a reference, aka CID-056ad39ee925. a función usb_sg_cancel en el archivo drivers/usb/core/message.c en el kernel de Linux versiones anteriores a la versión 5.6.8, tiene un uso de la memoria previamente liberada porque se produce una transferencia sin una referencia, también se conoce como CID-056ad39ee925. A use-after-free flaw was found in usb_sg_cancel in drivers/usb/core/message.c in the USB core subsystem. This flaw allows a local attacker with a special user or root privileges to crash the system due to a race problem in the scatter-gather cancellation and transfer completion in usb_sg_wait. This vulnerability can also lead to a leak of internal kernel information. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.6.8 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=056ad39ee9253873522f6469c3364964a322912b https://github.com/torvalds/linux/commit/056ad39ee9253873522f6469c3364964a322912b 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-a • CWE-416: Use After Free •
