An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable. This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance.

  - ** DISPUTED ** 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. (CVE-2019-12382)

  - An issue was discovered in the Linux kernel before     5.2.3. There is a use-after-free caused by a malicious     USB device in the drivers/media/usb/dvb-usb/dvb-usb-     init.c driver. (CVE-2019-15213)

  - An issue was discovered in xfs_setattr_nonsize in     fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS     partially wedges when a chgrp fails on account of being     out of disk quota. xfs_setattr_nonsize is failing to     unlock the ILOCK after the xfs_qm_vop_chown_reserve call     fails. This is primarily a local DoS attack vector, but     it might result as well in remote DoS if the XFS     filesystem is exported for instance via NFS.

  - In the Linux kernel before 5.1.13, there is a memory     leak in drivers/scsi/libsas/sas_expander.c when SAS     expander discovery fails. This will cause a BUG and     denial of service. (CVE-2019-15807)

  - An issue was discovered in the Linux kernel before     5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which     will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in the Linux kernel before     5.0.4. The 9p filesystem did not protect i_size_write()     properly, which causes an i_size_read() infinite loop     and denial of service on SMP systems. (CVE-2019-16413)

  - An issue was discovered in write_tpt_entry in     drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel     through 5.3.2. The cxgb4 driver is directly calling     dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of     Service, exploitable if this driver is used on an     architecture for which this stack/DMA interaction has     security relevance. (CVE-2019-17075)

  - The SCTP socket buffer used by a userspace application     is not accounted by the cgroups subsystem. An attacker     can use this flaw to cause a denial of service attack.

  - ax25_create in net/ax25/af_ax25.c in the AF_AX25     network module in the Linux kernel through 5.3.2 does     not enforce CAP_NET_RAW, which means that unprivileged     users can create a raw socket, aka     CID-0614e2b73768.(CVE-2019-17052)

  - ieee802154_create in net/ieee802154/socket.c in the     AF_IEEE802154 network module in the Linux kernel     through 5.3.2 does not enforce CAP_NET_RAW, which means     that unprivileged users can create a raw socket, aka     CID-e69dbd4619e7.(CVE-2019-17053)

  - atalk_create in net/appletalk/ddp.c in the AF_APPLETALK     network module in the Linux kernel through 5.3.2 does     not enforce CAP_NET_RAW, which means that unprivileged     users can create a raw socket, aka     CID-6cc03e8aa36c.(CVE-2019-17054)

  - base_sock_create in drivers/isdn/mISDN/socket.c in the     AF_ISDN network module in the Linux kernel through     5.3.2 does not enforce CAP_NET_RAW, which means that     unprivileged users can create a raw socket, aka     CID-b91ee4aa2a21.(CVE-2019-17055)

  - llcp_sock_create in net/nfc/llcp_sock.c in the AF_NFC     network module in the Linux kernel through 5.3.2 does     not enforce CAP_NET_RAW, which means that unprivileged     users can create a raw socket, aka     CID-3a359798b176.(CVE-2019-17056)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

New kernel packages are available for Slackware 14.2 to fix security issues.
