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.

low complexity
linux canonical CWE-787
7.2
2021-06-04 CVE-2021-3491 Out-of-bounds Write vulnerability in multiple products
The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem.

7.2
2021-05-26 CVE-2020-27815 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
A flaw was found in the JFS filesystem code in the Linux Kernel which allows a local attacker with the ability to set extended attributes to panic the system, causing memory corruption or escalating privileges.
local
low complexity
linux debian netapp CWE-119
7.8
2021-05-26 CVE-2020-25668 Improper Synchronization vulnerability in multiple products
