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.

2021-06-04 CVE-2021-3489 Out-of-bounds Write vulnerability in multiple products
The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution.

2021-06-04 CVE-2021-3490 Out-of-bounds Write vulnerability in multiple products
The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution.

2021-03-22 CVE-2021-28972 Classic Buffer Overflow vulnerability in multiple products
In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly.
