The input parameter passed in register x1 is not validated well enough in the function sdei_interrupt_bind. The parameter is passed to a call to plat_ic_get_interrupt_type. It can be any arbitrary value passing checks in the function plat_ic_is_sgi. A compromised Normal World (Linux kernel) can enable a root-privileged attacker to issue arbitrary SMC calls. Using this primitive, he can control the content of registers x0 through x6, which are used to send parameters to TF-A. Out-of-bounds addresses can be read in the context of TF-A (EL3). Because the read value is never returned to non-secure memory or in registers, no leak is possible. An attacker can still crash TF-A, however.","severity":{"version":"3.1","score":4.4,"vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","level":"medium","assessor":"adp","from":"cve"},"epss":{"day":"2026-11-09","score":0.00224,"percentile":0.13138,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-125"],"published":"2024-02-21T00:00:00Z","modified":"2026-10-28T02:30:27Z","fixes":[{"ecosystem":"Alpine:v3.18","package":"arm-trusted-firmware","fixed_in":["2.8.14-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.19","package":"arm-trusted-firmware","fixed_in":["2.8.14-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.20","package":"arm-trusted-firmware","fixed_in":["2.8.14-r0"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"arm-trusted-firmware","fixed_in":["2.10.0+dfsg-1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"arm-trusted-firmware","fixed_in":["2.10.0+dfsg-1"],"sources":["osv"]},{"ecosystem":"openEuler:20.03-LTS-SP1","package":"arm-trusted-firmware","fixed_in":["1.6-4.oe1"],"sources":["osv"]},{"ecosystem":"openEuler:20.03-LTS-SP4","package":"arm-trusted-firmware","fixed_in":["1.6-4.oe2003sp4"],"sources":["osv"]},{"ecosystem":"openEuler:22.03-LTS","package":"arm-trusted-firmware","fixed_in":["2.3-4.oe2203sp3"],"sources":["osv"]},{"ecosystem":"openEuler:22.03-LTS-SP1","package":"arm-trusted-firmware","fixed_in":["2.3-4.oe2203sp1"],"sources":["osv"]},{"ecosystem":"openEuler:22.03-LTS-SP2","package":"arm-trusted-firmware","fixed_in":["2.3-4.oe2203sp2"],"sources":["osv"]},{"ecosystem":"openEuler:22.03-LTS-SP3","package":"arm-trusted-firmware","fixed_in":["2.3-4.oe2203sp3"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Alpine:v3.18","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.8.14-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.19","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.8.14-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.20","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.8.14-r0"}]}]},{"source":"osv","ecosystem":"Debian:12","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.10.0+dfsg-1","2.10.10+dfsg-1","2.12.0+dfsg-1","2.12.0+dfsg-2","2.12.1+dfsg-1","2.12.16+dfsg-1","2.8.0+dfsg-1","2.9.0+dfsg-1","2.9.0+dfsg-2","2.9.0+dfsg-3"]},{"source":"osv","ecosystem":"Debian:13","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.10.0+dfsg-1"}]}]},{"source":"osv","ecosystem":"Debian:14","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.10.0+dfsg-1"}]}]},{"source":"osv","ecosystem":"openEuler:20.03-LTS-SP1","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6-4.oe1"}]}]},{"source":"osv","ecosystem":"openEuler:20.03-LTS-SP4","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6-4.oe2003sp4"}]}]},{"source":"osv","ecosystem":"openEuler:22.03-LTS","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3-4.oe2203sp3"}]}]},{"source":"osv","ecosystem":"openEuler:22.03-LTS-SP1","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3-4.oe2203sp1"}]}]},{"source":"osv","ecosystem":"openEuler:22.03-LTS-SP2","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3-4.oe2203sp2"}]}]},{"source":"osv","ecosystem":"openEuler:22.03-LTS-SP3","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3-4.oe2203sp3"}]}]},{"source":"osv","ecosystem":"Ubuntu:20.04:LTS","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1-3","2.2-2"]},{"source":"osv","ecosystem":"Ubuntu:22.04:LTS","package":"arm-trusted-firmware","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5+dfsg-1","2.6+dfsg-1"]}],"references":[{"url":"https://github.com/ARM-software/arm-trusted-firmware/blob/a05414bedc9b1cc35cf0795ce641b6b4db5bc97e/services/std_svc/sdei/sdei_main.c#L708","tags":["x_transferred","web"]},{"url":"https://github.com/ARM-software/arm-trusted-firmware/blob/a05414bedc9b1cc35cf0795ce641b6b4db5bc97e/services/std_svc/sdei/sdei_main.c#L714","tags":["x_transferred","web"]},{"url":"https://trustedfirmware-a.readthedocs.io/en/latest/security_advisories/security-advisory-tfv-11.html","tags":["x_transferred","advisory","report"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-49100","tags":["advisory"]},{"url":"https://github.com/advisories/GHSA-rmvf-wrpj-7c43"},{"url":"https://security.alpinelinux.org/vuln/CVE-2023-49100","tags":["advisory"]},{"url":"https://github.com/CVEP
