https://notcve.org/view.php?id=CVE-2020-12659
An issue was discovered in the Linux kernel before 5.6.7. xdp_umem_reg in net/xdp/xdp_umem.c has an out-of-bounds write (by a user with the CAP_NET_ADMIN capability) because of a lack of headroom validation. Se detectó un problema en el kernel de Linux versiones anteriores a 5.6.7. En la función xdp_umem_reg en el archivo net/xdp/xdp_umem.c se presenta una escritura fuera de límites (por un usuario con la capacidad CAP_NET_ADMIN) debido a una falta de comprobación del headroom. An out-of-bounds (OOB) memory access flaw was found in the Network XDP (the eXpress Data Path) module in the Linux kernel's xdp_umem_reg function in net/xdp/xdp_umem.c. When a user with special user privilege of CAP_NET_ADMIN (or root) calls setsockopt to register umem ring on XDP socket, passing the headroom value larger than the available space in the chunk, it leads to an out-of-bounds write, causing panic or possible memory corruption. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html https://bugzilla.kernel.org/show_bug.cgi?id=207225 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.6.7 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=99e3a236dd43d06c65af0a2ef9cb44306aef6e02 https://github.com/torvalds/linux/commit/99e3a236dd43d06c65af0a2ef9cb44306aef6e02 https://security.netapp.com/advisory/ntap-20200608-0001 https://usn.ubuntu.com/4387-1 https://usn.ubuntu.com/4388- • CWE-787: Out-of-bounds Write •

An array overflow was discovered in mt76_add_fragment in drivers/net/wireless/mediatek/mt76/dma.c in the Linux kernel before 5.5.10, aka CID-b102f0c522cf. An oversized packet with too many rx fragments can corrupt memory of adjacent pages.
