kernel: denial of service in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c

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.

kernel: unprivileged access to llcp_sock_create in net/nfc/llcp_sock.c in the AF_NFC socket type.

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.

kernel: unprivileged users able to create RAW sockets in AF_ISDN network protocol

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.

kernel: privilege escalation in atalk_create in net/appletalk/ddp.c in the AF_APPLETALK network module

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.

kernel: unprivileged users able to create RAW sockets in AF_IEEE802154 network protocol

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.

kernel: unprivileged users able to create RAW sockets in the the AF_AX25 network protocol.

ax25_create in net/ax25/af_ax25.c in the AF_AX25 network module in the Linux kernel 3.16 through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-0614e2b73768.

An issue was discovered in BMC Patrol Agent 9.0.10i. Weak execution permissions on the PatrolAgent SUID binary could allow an attacker with "patrol" privileges to elevate his/her privileges to the ones of the "root" user by specially crafting a shared library .so file that will be loaded during execution.

kernel: Memory leak in hsr_dev_finalize() in net/hsr/hsr_device.c

In the Linux kernel before 5.0.3, a memory leak exits in hsr_dev_finalize() in net/hsr/hsr_device.c if hsr_add_port fails to add a port, which may cause denial of service, aka CID-6caabe7f197d.

kernel: Memory leak in sit_init_net() in net/ipv6/sit.c

In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka CID-07f12b26e21a.

kernel: information disclosure in hns_roce_alloc_ucontext in drivers/infiniband/hw/hns/hns_roce_main.c

In the Linux kernel before 4.17, hns_roce_alloc_ucontext in drivers/infiniband/hw/hns/hns_roce_main.c does not initialize the resp data structure, which might allow attackers to obtain sensitive information from kernel stack memory, aka CID-df7e40425813.

kernel: buffer-overflow hardening in WiFi beacon validation code.

An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check the length of variable elements in a beacon head, leading to a buffer overflow.

kernel: vulnerability in rds6_inc_info_copy in net/rds/recv.c allows attackers to obtain sensitive information

In the Linux kernel before 5.2.14, rds6_inc_info_copy in net/rds/recv.c allows attackers to obtain sensitive information from kernel stack memory because tos and flags fields are not initialized.

kernel: i_size_read() infinite loop leads to denial of service

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.

kernel: null pointer dereference in drivers/net/wireless/intel/iwlwifi/pcie/trans.c

drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.

kernel: null pointer dereference in drivers/scsi/qla2xxx/qla_os.c

drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.

kernel: null-pointer dereference in drivers/net/wireless/marvell/libertas/if_sdio.c

drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.

kernel: null-pointer dereference in drivers/net/fjes/fjes_main.c

drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.

kernel: null pointer dereference in drivers/gpu/drm/amd/amdkfd/kfd_interrupt.c

drivers/gpu/drm/amd/amdkfd/kfd_interrupt.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. NOTE: The security community disputes this issues as not being serious enough to be deserving a CVE id

kernel: out-of-bounds in function build_audio_procunit in sound/usb/mixer.c

An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function build_audio_procunit in the file sound/usb/mixer.c.

kernel: out of bounds access in functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx

An issue was discovered in the Linux kernel before 5.2.3. Out of bounds access exists in the functions ath6kl_wmi_pstream_timeout_event_rx and ath6kl_wmi_cac_event_rx in the file drivers/net/wireless/ath/ath6kl/wmi.c.
