CVE-2021-38201 – kernel: slab-out-of-bounds access in xdr_set_page_base() in net/sunrpc/xdr.c
https://notcve.org/view.php?id=CVE-2021-38201
net/sunrpc/xdr.c in the Linux kernel before 5.13.4 allows remote attackers to cause a denial of service (xdr_set_page_base slab-out-of-bounds access) by performing many NFS 4.2 READ_PLUS operations. El archivo net/sunrpc/xdr.c en el kernel de Linux versiones anteriores a 5.13.4, permite a atacantes remotos causar una denegación de servicio (acceso fuera de los límites de xdr_set_page_base) al llevar a cabo muchas operaciones NFS 4.2 READ_PLUS A flaw was found in the Linux kernel that allows remote attackers to cause a denial of service (xdr_set_page_base slab-out-of-bounds access) by performing many NFS 4.2 READ_PLUS operations. The highest threat from this vulnerability is to system availability. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.4 https://github.com/torvalds/linux/commit/6d1c0f3d28f98ea2736128ed3e46821496dc3a8c https://security.netapp.com/advisory/ntap-20210902-0010 https://access.redhat.com/security/cve/CVE-2021-38201 https://bugzilla.redhat.com/show_bug.cgi?id=1992731 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

fs/nfsd/trace.h in the Linux kernel before 5.13.4 might allow remote attackers to cause a denial of service (out-of-bounds read in strlen) by sending NFS traffic when the trace event framework is being used for nfsd. El archivo fs/nfsd/trace.h en el kernel de Linux versiones anteriores a 5.13.4, podría permitir a atacantes remotos causar una denegación de servicio (lectura fuera de los límites en strlen) mediante el envío de tráfico NFS cuando el marco de eventos de rastreo se está usando para nfsd • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.4 https://github.com/torvalds/linux/commit/7b08cf62b1239a4322427d677ea9363f0ab677c6 https://security.netapp.com/advisory/ntap-20210902-0010 • CWE-125: Out-of-bounds Read •

drivers/usb/host/max3421-hcd.c in the Linux kernel before 5.13.6 allows physically proximate attackers to cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain situations. El archivo drivers/usb/host/max3421-hcd.c en el kernel de Linux versiones anteriores a 5.13.6, permite a atacantes físicamente próximos causar una denegación de servicio (uso de memoria previamente liberada y pánico) al eliminar un dispositivo USB MAX-3421 en determinadas situaciones • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.6 https://github.com/torvalds/linux/commit/b5fdf5c6e6bee35837e160c00ac89327bdad031b https://lists.debian.org/debian-lts-announce/2021/12/msg00012.html • CWE-416: Use After Free •
