DATE CVE VULNERABILITY TITLE RISK
2021-09-19 CVE-2021-41073 Release of Invalid Pointer or Reference vulnerability in multiple products
loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/<pid>/maps for exploitation.

2021-08-08 CVE-2021-38201 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
net/sunrpc/xdr.c in the Linux kernel before 5.13.4 allows remote attackers to cause a denial of service (xdr_set_page_base slab-out-of-bounds access) by performing many NFS 4.2 READ_PLUS operations.

7.5
2021-08-08 CVE-2021-38202 Out-of-bounds Read vulnerability in multiple products
fs/nfsd/trace.h in the Linux kernel before 5.13.4 might allow remote attackers to cause a denial of service (out-of-bounds read in strlen) by sending NFS traffic when the trace event framework is being used for nfsd.

2021-08-08 CVE-2021-38207 Classic Buffer Overflow vulnerability in Linux Kernel
drivers/net/ethernet/xilinx/ll_temac_main.c in the Linux kernel before 5.12.13 allows remote attackers to cause a denial of service (buffer overflow and lockup) by sending heavy network traffic for about ten minutes.

2021-07-26 CVE-2021-37576 Out-of-bounds Write vulnerability in multiple products
arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e.

2021-07-22 CVE-2021-29657 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Linux Kernel
arch/x86/kvm/svm/nested.c in the Linux kernel before 5.11.12 has a use-after-free in which an AMD KVM guest can bypass access control on host OS MSRs when there are nested guests, aka CID-a58d9166a756.

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.
