found in GDB's STABS debug format parser. The\nread_member_functions() function in gdb/stabsread.c contains a linked\nlist removal bug in the code that separates destructor and non-destructor\nmember functions of C++ classes. The bug causes the destructor entries to\nremain in the main function list while the list length counter is\ndecremented, resulting in an out-of-bounds write when the function list\nis copied to its final allocated array. An attacker can craft an ELF\nbinary with malicious .stab and .stabstr sections that triggers this\nout-of-bounds write when a user opens the file in GDB and performs any\nsymbol-inspection operation such as setting a breakpoint. The inferior\nprocess does not need to be executed. Under controlled conditions, this\nwas demonstrated to achieve execution of arbitrary commands within the\nGDB process.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.aarch64","SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.ppc64le","SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.s390x","SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2026-13732","url":"https://www.suse.com/security/cve/CVE-2026-13732"},{"category":"external","summary":"SUSE Bug 1277757 for CVE-2026-13732","url":"https://bugzilla.suse.com/1277757"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.aarch64","SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.ppc64le","SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.s390x","SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":7.8,"baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"products":["SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.aarch64","SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.ppc64le","SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.s390x","SUSE Linux Micro Extras 6.2:gdb-0:16.3-160000.6.1.x86_64"]}],"threats":[{"category":"impact","date":"2026-09-20T13:53:47Z","details":"important"}],"title":"CVE-2026-13732"}]}
