12 Dec 2019 — In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-buffer). En el kernel de Linux versión 5.4.0-rc2, se presenta un uso de la memoria previamente liberada en la función __blk_add_trace en el archivo kernel/trace/blktrace.c (que se usa para completar una estructura blk_io_trace y colocarla en un per-cpu sub-buffer).

08 Dec 2019 — In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure.

08 Dec 2019 — In the Linux kernel 5.0.21, mounting a crafted ext4 filesystem image, performing some operations, and unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in fs/ext4/super.c. En el kernel de Linux versión 5.0.21, montando una imagen de sistema de archivos ext4 diseñada, al realizar algunas operaciones y desmontarla puede conllevar a un uso de la memoria previamente liberada en la función ext4_put_super en el archivo fs/ext4/super.c, relacionado con la fun... • https://github.com/Trinadh465/linux-4.19.72_CVE-2019-19447 • CWE-416: Use After Free •

05 Dec 2019 — fpregs_state_valid in arch/x86/include/asm/fpu/internal.h in the Linux kernel before 5.4.2, when GCC 9 is used, allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact because of incorrect fpu_fpregs_owner_ctx caching, as demonstrated by mishandling of signal-based non-cooperative preemption in Go 1.14 prereleases on amd64, aka CID-59c4bd853abc.

30 Nov 2019 — relay_open in kernel/relay.c in the Linux kernel through 5.4.1 allows local users to cause a denial of service (such as relay blockage) by triggering a NULL alloc_percpu result. La función relay_open en el archivo kernel/relay.c en el kernel de Linux versiones hasta 5.4.1, permite a usuarios locales causar una denegación de servicio (tal y como un bloqueo de retransmisión) al desencadenar un resultado NULL de alloc_percpu.

29 Nov 2019 — A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html • CWE-122: Heap-based Buffer Overflow CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •

29 Nov 2019 — A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA.

29 Nov 2019 — A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code.
