Prior to 9.2.0846, set_sofo() in src/spellfile.c reuses sl_sal_first[] without resetting values left by set_sal_first(), so a crafted spell file containing an SN_SAL section before an SN_SOFO section causes under-counted mapping lists and attacker-influenced writes beyond a heap allocation. This issue is fixed in version 9.2.0846. ## Affected - `vim < 9.2.0846` ## Remediation Upgrade past the affected range: - `vim 9.2.0846` ## Vendor advisories - **RHSA-2026:66336** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 10), Red Hat Enterprise Linux BaseOS (v. 10) · released 2026-09-10 · [advisory](https://access.redhat.com/errata/RHSA-2026:66336) - **RHSA-2026:66348** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 8), Red Hat Enterprise Linux BaseOS (v. 8) · released 2026-09-10 · [advisory](https://access.redhat.com/errata/RHSA-2026:66348) - **RHSA-2026:66366** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 9), Red Hat Enterprise Linux BaseOS (v. 9) · released 2026-09-10 · [advisory](https://access.redhat.com/errata/RHSA-2026:66366) - **Red Hat VEX** · Important · affected: Red Hat Enterprise Linux 6 · no fix planned: Red Hat Enterprise Linux 6 · updated 2026-10-14 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-73072.json) - **RHSA-2026:68711** · Red Hat · fixed in: Red Hat Enterprise Linux Server (v. 7 ELS) · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68711) - **RHSA-2026:67956** · Red Hat · fixed in: Red Hat Update Infrastructure 5 · released 2026-09-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:67956) - **RHSA-2026:70818** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v.9.6), Red Hat Enterprise Linux BaseOS EUS (v.9.6) · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:70818) - **RHSA-2026:71603** · Red Hat · fixed in: Red Hat Update Infrastructure 5 · released 2026-09-24 · [advisory](https://access.redhat.com/errata/RHSA-2026:71603) - **RHSA-2026:72466** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream E4S (v.9.2), Red Hat Enterprise Linux BaseOS E4S (v.9.2) · released 2026-09-28 · [advisory](https://access.redhat.com/errata/RHSA-2026:72466) - **RHSA-2026:72465** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream E4S (v.9.4), Red Hat Enterprise Linux BaseOS E4S (v.9.4) · released 2026-09-28 · [advisory](https://access.redhat.com/errata/RHSA-2026:72465) - **RHSA-2026:73859** · Red Hat · fixed in: Red Hat AI Inference Server 3.2 · released 2026-09-30 · [advisory](https://access.redhat.com/errata/RHSA-2026:73859) - **RHSA-2026:73929** · Red Hat · fixed in: Red Hat AI Inference Server 3.2 · released 2026-09-30 · [advisory](https://access.redhat.com/errata/RHSA-2026:73929) - **RHSA-2026:73930** · Red Hat · fixed in: Red Hat AI Inference Server 3.2 · released 2026-09-30 · [advisory](https://access.redhat.com/errata/RHSA-2026:73930) - **RHSA-2026:73960** · Red Hat · fixed in: Red Hat OpenShift AI 3.0 · released 2026-09-30 · [advisory](https://access.redhat.com/errata/RHSA-2026:73960) - **RHSA-2026:82066** · Red Hat · fixed in: Red Hat AI Inference Server 3.5 · released 2026-10-13 · [advisory](https://access.redhat.com/errata/RHSA-2026:82066)
