CVE-2026-81880 radare2: Uncontrolled resource consumption in radare2 PEF loader

radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's Apple Preferred Executable Format loader was vulnerable because the PEF loader accepted relocSecCount values that were not bounded by the number of sections or complete relocation records in t...

CVE-2026-81879

radare2 is a UNIX-like reverse engineering framework and command-line toolset. Prior to 6.2.0, radare2's ELF PNXNUM handling was vulnerable because the ELF parser allocated the program-header array using the resolved PNXNUM count but several consumers still iterated with the original ephnum value...

CVE-2026-81879

radare2 (a UNIX-like reverse engineering framework) is vulnerable to a heap out-of-bounds read in its ELF parser's PN_XNUM handling prior to version 6.2.0. The root cause is a mismatch: the program-header array is allocated using the resolved PN_XNUM count, but several consumers still iterate usi...
