CVE-2021-47245

CVE-2021-47245 affects the Linux kernel netfilter synproxy TCP option parser. The vulnerability arises from an out-of-bounds read in synproxy_parse_options when parsing TCP options; if length equals 1, the loop reads an opcode byte and, if it is not TCPOPT_EOL or TCPOPT_NOP, reads one more byte, ...

CVE-2021-47243

The CVE-2021-47243 issue concerns the Linux kernel's cake_qdisc TCP option parser. Affected code paths cake_get_tcpopt and cake_tcph_may_drop could read one byte out of bounds when processing TCP options, particularly if the option length is 1, leading to a second read for opcodes not equal to TC...

CVE-2021-47244

The CVE-2021-47244 entry concerns the Linux kernel mptcp option parsing (mptcp_get_options). The vulnerability is a potential out-of-bounds read when parsing TCP options: if an option’s length is 1, the parser loops and reads the opcode byte; if the opcode is not TCPOPT_EOL or TCPOPT_NOP, it read...
