CVE-2020-35519 1 Linux 1 Linux Kernel 2021-06-18 6.8 MEDIUM 7.8 HIGH
An out-of-bounds (OOB) memory access flaw was found in x25_bind in net/x25/af_x25.c in the Linux kernel version v5.12-rc5. A bounds check failure allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-3501 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2021-06-18 3.6 LOW 7.1 HIGH
A flaw was found in the Linux kernel in versions before 5.12. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability.

An issue was discovered in the Linux kernel before 5.8.1. net/bluetooth/hci_event.c has a slab out-of-bounds read in hci_extended_inquiry_result_evt, aka CID-51c19bf3d5cf.
CVE-2019-16746 1 Linux 1 Linux Kernel 2021-06-14 7.5 HIGH 9.8 CRITICAL
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.
CVE-2019-19074 1 Linux 1 Linux Kernel 2021-06-14 7.8 HIGH 7.5 HIGH
A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-728c1e2a05e4.
CVE-2019-20812 1 Linux 1 Linux Kernel 2021-06-14 4.9 MEDIUM 5.5 MEDIUM
An issue was discovered in the Linux kernel before 5.4.7. The prb_calc_retire_blk_tmo() function in net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain failure case involving TPACKET_V3, aka CID-b43d1f9f7067.
CVE-2019-17133 1 Linux 1 Linux Kernel 2021-06-14 7.5 HIGH 9.8 CRITICAL
In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow.
CVE-2019-10638 1 Linux 1 Linux Kernel 2021-06-14 4.3 MEDIUM 6.5 MEDIUM
In the Linux kernel before 5.1.7, a device can be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses.
CVE-2019-17075 1 Linux 1 Linux Kernel 2021-06-14 7.1 HIGH 7.5 HIGH
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-2019-15218 1 Linux 1 Linux Kernel 2021-06-14 4.9 MEDIUM 4.6 MEDIUM
An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/siano/smsusb.c driver.
