{"id":"CVE-2026-43256","summary":"media: qcom: camss: vfe: Fix out-of-bounds access in vfe_isr_reg_update()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: qcom: camss: vfe: Fix out-of-bounds access in vfe_isr_reg_update()\n\nvfe_isr() iterates using MSM_VFE_IMAGE_MASTERS_NUM(7) as the loop\nbound and passes the index to vfe_isr_reg_update(). However,\nvfe-\u003eline[] array is defined with VFE_LINE_NUM_MAX(4):\n\n    struct vfe_line line[VFE_LINE_NUM_MAX];\n\nWhen index is 4, 5, 6, the access to vfe-\u003eline[line_id] exceeds\nthe array bounds and resulting in out-of-bounds memory access.\n\nFix this by using separate loops for output lines and write masters.","modified":"2026-06-18T03:55:04.380436593Z","published":"2026-05-06T11:28:45.209Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43256.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0c074e80921fd18984b75836730d76c768c84f65"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1b103307df6d461a0731be25aca69ad0335b0933"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d965919af524e68cb2ab1a685872050ad2ee933d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e6cbf765686fb6c1d8f2530b3daf6c66efc92f5d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e7a38ecda2498e7ce998793ac2a46ca47317635d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fade67c88870f497a13ed450ba01f7236c92dd9b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43256.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43256"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4edc8eae715cecf5f8bf12a0c77c281f336c37db"},{"fixed":"e6cbf765686fb6c1d8f2530b3daf6c66efc92f5d"},{"fixed":"0c074e80921fd18984b75836730d76c768c84f65"},{"fixed":"1b103307df6d461a0731be25aca69ad0335b0933"},{"fixed":"fade67c88870f497a13ed450ba01f7236c92dd9b"},{"fixed":"e7a38ecda2498e7ce998793ac2a46ca47317635d"},{"fixed":"d965919af524e68cb2ab1a685872050ad2ee933d"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43256.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.18.0"},{"fixed":"6.1.167"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.128"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43256.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
