CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2019-12382 – kernel: unchecked kstrdup of fwstr in drm_load_edid_firmware leads to denial of service
https://notcve.org/view.php?id=CVE-2019-12382
An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel through 5.1.5. There is an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: The vendor disputes this issues as not being a vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance for a NULL pointer dereference ** EN DISPUTA ** Un problema fue encontrado en la función drm_load_edid_firmware en el archivo driver/gpu/drm/drm_edid_load.c en el kernel de Linux hasta la versión 5.1.5. Se presenta un kstrdup sin comprobar de fwstr, que podría permitir que un atacante genere una Denegación de Servicio (desreferencia de puntero NULL y bloqueo del sistema). NOTA: El proveedor niega que estos problemas no sean una vulnerabilidad porque kstrdup () que devuelve NULL se trata de manera suficiente y no hay posibilidad de que se elimine la referencia al puntero NULL. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00040.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00048.html http://www.securityfocus.com/bid/108474 https://cgit.freedesktop.org/drm/drm-misc/commit/?id=9f1f1a2dab38d4ce87a13565cf4dc1b73bef3a5f https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J36BIJTKEPUOZKJNHQBUZA47RQONUKOI https://lists.fedoraproject.org/archives/list&# • CWE-476: NULL Pointer Dereference •

An issue was discovered in ip_ra_control in net/ipv4/ip_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: this is disputed because new_ra is never used if it is NULL ** EN DISPUTA ** Un problema fue encontrado en la función ip_ra_control en el archivo net/ipv4/ip_sockglue.c en el kernel de Linux hasta la versión 5.1.5.

**DISPUTED** An issue was discovered in the efi subsystem in the Linux kernel through 5.1.5. phys_efi_set_virtual_address_map in arch/x86/platform/efi/efi.c and efi_call_phys_prolog in arch/x86/platform/efi/efi_64.c mishandle memory allocation failures. NOTE: This id is disputed as not being an issue because “All the code touched by the referenced commit runs only at boot, before any user processes are started.
