0 A vulnerability in the Linux kernel's batman-adv mesh networking subsystem was resolved. The issue involved a signed 16-bit integer field last_changeset_len that could wrap to a negative value when assigned a value greater than 32767, leading to uninitialized memory usage during buffer population. This flaw was fixed by changing the field to an unsigned 16-bit integer to prevent sign extension errors. The vulnerability affects multiple Linux kernel versions prior to specific 5.15.x updates. A high severity CVSS score of 9.8 indicates critical impact potential. Official patches are available and should be applied. No known exploits are reported in the wild.
