DATE CVE VULNERABILITY TITLE RISK
2021-07-20 CVE-2021-33909 Integer Overflow or Wraparound vulnerability in multiple products
fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user, aka CID-8cae8cd89f05.
7.8
2021-07-09 CVE-2021-3612 Out-of-bounds Write vulnerability in multiple products
An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP.
7.8
2021-06-23 CVE-2021-33624 Type Confusion vulnerability in multiple products
In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a side-channel attack, aka CID-9183671af6db.

7.8
2021-05-24 CVE-2020-26558 Improper Authentication vulnerability in multiple products
Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session.
4.2
2021-05-14 CVE-2021-33034 Use After Free vulnerability in multiple products
In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409.
