{"id":"CVE-2026-45988","summary":"rxrpc: Fix re-decryption of RESPONSE packets","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Fix re-decryption of RESPONSE packets\n\nIf a RESPONSE packet gets a temporary failure during processing, it may end\nup in a partially decrypted state - and then get requeued for a retry.\n\nFix this by just discarding the packet; we will send another CHALLENGE\npacket and thereby elicit a further response.  Similarly, discard an\nincoming CHALLENGE packet if we get an error whilst generating a RESPONSE;\nthe server will send another CHALLENGE.","modified":"2026-06-18T03:57:42.808307341Z","published":"2026-05-27T12:55:39.740Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45988.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0422e7a4883f25101903f3e8105c0808aa5f4ce9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/76cb9a2d252274adfae6e293a292434631a7d472"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7b89868305052b94a91b708c462bc2281fa42a4a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d61482be4aae1835b78875761206241835a7510e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f55b383070170e988e4dec28be2af1714d258521"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45988.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45988"},{"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":"17926a79320afa9b95df6b977b40cca6d8713cea"},{"fixed":"d61482be4aae1835b78875761206241835a7510e"},{"fixed":"7b89868305052b94a91b708c462bc2281fa42a4a"},{"fixed":"76cb9a2d252274adfae6e293a292434631a7d472"},{"fixed":"f55b383070170e988e4dec28be2af1714d258521"},{"fixed":"0422e7a4883f25101903f3e8105c0808aa5f4ce9"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-45988.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.22"},{"fixed":"6.6.140"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.86"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.27"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-45988.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
