4 security issues in bookworm high

There are 4 open security issues in bookworm.

1 important issue:

CVE-2026-107891:

3 issues postponed or untriaged:

CVE-2026-6042: (needs triaging) A security flaw has been discovered in musl libc up to 1.2.6. Affected is the function iconv of the file src/locale/iconv.c of the component GB18030 4-byte Decoder. Performing a manipulation results in inefficient algorithmic complexity. The attack must be initiated from a local position. To fix this issue, it is recommended to deploy a patch.
CVE-2025-26519: (needs triaging) musl libc 0.9.13 through 1.2.5 before 1.2.6 has an out-of-bounds write vulnerability when an attacker can trigger iconv conversion of untrusted EUC-KR text to UTF-8.
CVE-2026-40200: (needs triaging) An issue was discovered in musl libc 0.7.10 through 1.2.6. Stack-based memory corruption can occur during qsort of very large arrays, due to incorrectly implemented double-word primitives. The number of elements must exceed about seven million, i.e., the 32nd Leonardo number on 32-bit platforms (or the 64th Leonardo number on 64-bit platforms, which is not practical).

testing migrations

excuses:
- Migration status for musl (1.2.6-1 to 1.2.6-2): BLOCKED: Maybe temporary, maybe blocked but Britney is missing information (check below)
- Issues preventing migration:
- ∙ ∙ Missing build on riscv64
- ∙ ∙ Autopkgtest deferred on riscv64: missing arch:riscv64 build
- ∙ ∙ Autopkgtest for musl/1.2.6-2: amd64: Pass, arm64: Pass, armhf: Pass, i386: Test triggered, ppc64el: Pass, s390x: Pass
- ∙ ∙ Lintian check waiting for test results on riscv64 - info
- ∙ ∙ Reproducibility check waiting for results on i386 - info
- ∙ ∙ Too young, only 0 of 2 days old
- Additional info (not blocking):
- ∙ ∙ Piuparts tested OK - https://piuparts.debian.org/sid/source/m/musl.html
- ∙ ∙ Reproduced on amd64 - info
- ∙ ∙ Reproduced on arm64 - info
- ∙ ∙ Reproduced on armhf - info
- Not considered
