{"id":"DEBIAN-CVE-2025-37929","details":"In the Linux kernel, the following vulnerability has been resolved:  arm64: errata: Add missing sentinels to Spectre-BHB MIDR arrays  Commit a5951389e58d (\"arm64: errata: Add newer ARM cores to the spectre_bhb_loop_affected() lists\") added some additional CPUs to the Spectre-BHB workaround, including some new arrays for designs that require new 'k' values for the workaround to be effective.  Unfortunately, the new arrays omitted the sentinel entry and so is_midr_in_range_list() will walk off the end when it doesn't find a match. With UBSAN enabled, this leads to a crash during boot when is_midr_in_range_list() is inlined (which was more common prior to c8c2647e69be (\"arm64: Make  _midr_in_range_list() an exported function\")):   |  Internal error: aarch64 BRK: 00000000f2000001 [#1] PREEMPT SMP  |  pstate: 804000c5 (Nzcv daIF +PAN -UAO -TCO -DIT -SSBS BTYPE=--)  |  pc : spectre_bhb_loop_affected+0x28/0x30  |  lr : is_spectre_bhb_affected+0x170/0x190  | [...]  |  Call trace:  |   spectre_bhb_loop_affected+0x28/0x30  |   update_cpu_capabilities+0xc0/0x184  |   init_cpu_features+0x188/0x1a4  |   cpuinfo_store_boot_cpu+0x4c/0x60  |   smp_prepare_boot_cpu+0x38/0x54  |   start_kernel+0x8c/0x478  |   __primary_switched+0xc8/0xd4  |  Code: 6b09011f 54000061 52801080 d65f03c0 (d4200020)  |  ---[ end trace 0000000000000000 ]---  |  Kernel panic - not syncing: aarch64 BRK: Fatal exception  Add the missing sentinel entries.","modified":"2026-09-01T16:06:13.362779097Z","published":"2025-05-20T16:15:29.483Z","upstream":["CVE-2025-37929"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-37929"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.140-1"}]}],"versions":["6.1.106-1","6.1.106-2","6.1.106-3","6.1.112-1","6.1.115-1","6.1.119-1","6.1.123-1","6.1.124-1","6.1.128-1","6.1.129-1","6.1.133-1","6.1.135-1","6.1.137-1","6.1.139-1","6.1.27-1","6.1.37-1","6.1.38-1","6.1.38-2","6.1.38-2~bpo11+1","6.1.38-3","6.1.38-4","6.1.38-4~bpo11+1","6.1.52-1","6.1.55-1","6.1.55-1~bpo11+1","6.1.64-1","6.1.66-1","6.1.67-1","6.1.69-1","6.1.69-1~bpo11+1","6.1.76-1","6.1.76-1~bpo11+1","6.1.82-1","6.1.85-1","6.1.90-1","6.1.90-1~bpo11+1","6.1.94-1","6.1.94-1~bpo11+1","6.1.98-1","6.1.99-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-37929.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.29-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-37929.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.29-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-37929.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
