5.5
2021-08-02 CVE-2021-34556 Information Exposure Through Discrepancy vulnerability in multiple products
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack.

2021-08-02 CVE-2021-35477 Information Exposure Through Discrepancy vulnerability in multiple products
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value.

6.4
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
2021-07-07 CVE-2021-35039 Improper Verification of Cryptographic Signature vulnerability in multiple products
kernel/module.c in the Linux kernel before 5.12.14 mishandles Signature Verification, aka CID-0c18f29aae7c.
