An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-36916 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-36916/ (Markdown: https://insights.sbomify.com/CVE-2024-36916/index.md)","id":"CVE-2024-36916","markdown":"https://insights.sbomify.com/CVE-2024-36916/index.md","name":"CVE-2024-36916","record":{"aliases":["BELL-CVE-2024-36916","DEBIAN-CVE-2024-36916","UBUNTU-CVE-2024-36916"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An out-of-bounds shift in the Linux kernel's blk-iocost module can cause undefined behavior, potentially leading to system instability or crashes.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nblk-iocost: avoid out of bounds shift\n\nUBSAN catches undefined behavior in blk-iocost, where sometimes\niocg-\u003edelay is shifted right by a number that is too large,\nresulting in undefined behavior on some architectures.\n\n[  186.556576] ------------[ cut here ]------------\nUBSAN: shift-out-of-bounds in block/blk-iocost.c:1366:23\nshift exponent 64 is too large for 64-bit type 'u64' (aka 'unsigned long long')\nCPU: 16 PID: 0 Comm: swapper/16 Tainted: G S          E    N 6.9.0-0_fbk700_debug_rc2_kbuilder_0_gc85af715cac0 #1\nHardware name: Quanta Twin Lakes MP/Twin Lakes Passive MP, BIOS F09_3A23 12/08/2020\nCall Trace:\n \u003cIRQ\u003e\n dump_stack_lvl+0x8f/0xe0\n __ubsan_handle_shift_out_of_bounds+0x22c/0x280\n iocg_kick_delay+0x30b/0x310\n ioc_timer_fn+0x2fb/0x1f80\n __run_timer_base+0x1b6/0x250\n...\n\nAvoid that undefined behavior by simply taking the\n\"delay = 0\" branch if the shift is too large.\n\nI am not sure what the symptoms of an undefined value\ndelay will be, but I suspect it could be more than a\nlittle annoying to debug.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"blk-iocost: avoid out of bounds shift","id":"CVE-2024-36916","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","linux:linux_kernel"],"type":"integer_overflow","year":"2024"},"n_packages":0,"n_references":6,"next":{"headline":"block: fix overflow in blk_ioctl_discard()","id":"CVE-2024-36917"},"packages":[],"prev":{"headline":"nfc: llcp: fix nfc_llcp_setsockopt() unsafe copies","id":"CVE-2024-36915"},"products":["Linux"],"published":"2024-05-30","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"An out-of-bounds shift in the Linux kernel's blk-iocost module can cause undefined behavior, potentially leading to system instability or crashes.","url":"https://insights.sbomify.com/CVE-2024-36916/"}
