In the Linux kernel, the following vulnerability has been resolved: netfilter: xttcpmss: check remaining length before reading optlen Quoting reporter: In net/netfilter/xttcpmss.c lines 53-68, the TCP option parser reads opi+1 directly without validating the remaining option length. If the last...

CVE-2026-43171

The CVE-2026-43171 described affects the Linux kernel EFI/CPER component where cper_print_fw_err() does not validate the error-record length against the given offset, allowing an underflow that can cause dumping of large memory regions. Consequences include potential data disclosure and system in...

CVE-2026-43171 EFI/CPER: don't dump the entire memory region

In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: don't dump the entire memory region The current logic at cperprintfwerr doesn't check if the error record length is big enough to handle offset. On a bad firmware, if the ofset is above the actual record, length -= offs...

CVE-2026-43125 dlm: validate length in dlm_search_rsb_tree

In the Linux kernel, the following vulnerability has been resolved: dlm: validate length in dlmsearchrsbtree The len parameter in dlmdumprsbname is not validated and comes from network messages. When it exceeds DLMRESNAMEMAXLEN, it can cause out-of-bounds write in dlmsearchrsbtree. Add length...

CVE-2026-43125

CVE-2026-43125 affects the Linux kernel dlm module. The vulnerability stems from unvalidated length in dlm_dump_rsb_name() coming from network messages, allowing an out-of-bounds write in dlm_search_rsb_tree() when the length exceeds DLM_RESNAME_MAXLEN. This could enable denial of service and, in...
