The read_member_functions() function in gdb/stabsread.c contains a linked list removal bug in the code that separates destructor and non-destructor member functions of C++ classes. The bug causes the destructor entries to remain in the main function list while the list length counter is decremented, resulting in an out-of-bounds write when the function list is copied to its final allocated array. An attacker can craft an ELF binary with malicious .stab and .stabstr sections that triggers this out-of-bounds write when a user opens the file in GDB and performs any symbol-inspection operation such as setting a breakpoint. The inferior process does not need to be executed. Under controlled conditions, this was demonstrated to achieve execution of arbitrary commands within the GDB process.(CVE-2026-13732)","affected":[{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"gdb","purl":"pkg:rpm/openEuler/gdb&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"11.1-19.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["gdb-11.1-19.oe2203sp4.aarch64.rpm","gdb-debuginfo-11.1-19.oe2203sp4.aarch64.rpm","gdb-debugsource-11.1-19.oe2203sp4.aarch64.rpm","gdb-gdbserver-11.1-19.oe2203sp4.aarch64.rpm","gdb-headless-11.1-19.oe2203sp4.aarch64.rpm"],"noarch":["gdb-help-11.1-19.oe2203sp4.noarch.rpm"],"src":["gdb-11.1-19.oe2203sp4.src.rpm"],"x86_64":["gdb-11.1-19.oe2203sp4.x86_64.rpm","gdb-debuginfo-11.1-19.oe2203sp4.x86_64.rpm","gdb-debugsource-11.1-19.oe2203sp4.x86_64.rpm","gdb-gdbserver-11.1-19.oe2203sp4.x86_64.rpm","gdb-headless-11.1-19.oe2203sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4505"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13732"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"}],"database_specific":{"severity":"High"}}
