{"id":"CVE-2026-72076","summary":"Input: ims-pcu - fix out-of-bounds read in ims_pcu_irq() debug logging","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nInput: ims-pcu - fix out-of-bounds read in ims_pcu_irq() debug logging\n\nThe debug logging in ims_pcu_irq() unconditionally prints data from\npcu-\u003eurb_in_buf. However, if the interrupt fired for pcu-\u003eurb_ctrl, the\nactual data resides in pcu-\u003eurb_ctrl_buf. If urb-\u003eactual_length for the\ncontrol URB exceeds pcu-\u003emax_in_size, this leads to an out-of-bounds\nread.\n\nFix this by printing from the correct buffer associated with the URB.","modified":"2026-08-18T03:31:21.714606587Z","published":"2026-08-15T05:52:26.884Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72076.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/20fbf3ca0259d00664d1ede88837e1f11b49a88e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3fd7c0ace245334f2a0bd29fdcb680ad56e9b275"},{"type":"WEB","url":"https://git.kernel.org/stable/c/403b0a6970b1084bb27907c0f8225801fdd0fe1d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4d2553e9a76a11500ec670cbe16b7fd3da4832de"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9c964fc9507aeab74376ba9f892cf84ad6950dfe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b746e853721dee91e4234c033d1b90f4605705bb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e6153407d7edabc6ff98f0fda415d556c0bcb57a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f97bfc1a0766802a99167b3dc62d1ee7dca929fe"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72076.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72076"},{"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":"628329d52474323938a03826941e166bc7c8eff4"},{"fixed":"4d2553e9a76a11500ec670cbe16b7fd3da4832de"},{"fixed":"b746e853721dee91e4234c033d1b90f4605705bb"},{"fixed":"e6153407d7edabc6ff98f0fda415d556c0bcb57a"},{"fixed":"3fd7c0ace245334f2a0bd29fdcb680ad56e9b275"},{"fixed":"20fbf3ca0259d00664d1ede88837e1f11b49a88e"},{"fixed":"9c964fc9507aeab74376ba9f892cf84ad6950dfe"},{"fixed":"f97bfc1a0766802a99167b3dc62d1ee7dca929fe"},{"fixed":"403b0a6970b1084bb27907c0f8225801fdd0fe1d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72076.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.10.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72076.json"}}],"schema_version":"1.9.0"}
