  • CVE-2017-15649

    Use-after-free in af_packet.c.

    A vulnerability in fanout_add() in 'net/packet/af_packet.c' in the Linux kernel version 4.13.6 and older allows local users to gain privileges or cause a denial of service (kernel crash). A specially crafted sequence of system calls may trigger a race condition (involving fanout_add() and packet_do_bind() functions) that leads to a use-after-free.

  • CVE-2016-8399

    net: Out of bounds stack read in memcpy_fromiovec.

  • CVE-2017-12190

    Memory leak when merging buffers in SCSI IO vectors.

    It was found that in the Linux kernel through v4.14-rc5, bio_map_user_iov() and bio_unmap_user() in 'block/bio.c' do unbalanced pages refcounting if IO vector has small consecutive buffers belonging to the same page. bio_add_pc_page() merges them into one, but the page reference is never dropped, causing a memory leak and possible system lockup due to out-of-memory condition.

    A syntax vulnerability was discovered in the kernel's ASN1.1 DER decoder, which could lead to memory corruption or a complete local denial of service through x509 certificate DER files. A local system user could use a specially created key file to trigger BUG_ON() in the public_key_verify_signature() function (crypto/asymmetric_keys/public_key.c), to cause a kernel panic and crash the system.
