The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged code on the target system to exploit this vulnerability.(CVE-2022-2991)\r\n\r\nAn out-of-bounds memory read flaw was found in the Linux kernel\u0026apos;s BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data.(CVE-2022-2905)\r\n\r\nAn issue was discovered in the Linux kernel through 5.16-rc6.
