Description

This security bulletin contains information about 10 vulnerabilities.


1) Out-of-bounds write (CVE-ID: CVE-2025-7546)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the bfd_elf_set_group_contents() function in bfd/elf.c. A local user can trigger an out-of-bounds write and execute arbitrary code on the target system.
