It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-49933 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2024-49933/ (Markdown: https://insights.sbomify.com/CVE-2024-49933/index.md)","id":"CVE-2024-49933","markdown":"https://insights.sbomify.com/CVE-2024-49933/index.md","name":"CVE-2024-49933","record":{"aliases":["AZL-52941","BELL-CVE-2024-49933","DEBIAN-CVE-2024-49933","GHSA-66x6-php2-c8mm","UBUNTU-CVE-2024-49933"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","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":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nblk_iocost: fix more out of bound shifts\n\nRecently running UBSAN caught few out of bound shifts in the\nioc_forgive_debts() function:\n\nUBSAN: shift-out-of-bounds in block/blk-iocost.c:2142:38\nshift exponent 80 is too large for 64-bit type 'u64' (aka 'unsigned long\nlong')\n...\nUBSAN: shift-out-of-bounds in block/blk-iocost.c:2144:30\nshift exponent 80 is too large for 64-bit type 'u64' (aka 'unsigned long\nlong')\n...\nCall Trace:\n\u003cIRQ\u003e\ndump_stack_lvl+0xca/0x130\n__ubsan_handle_shift_out_of_bounds+0x22c/0x280\n? __lock_acquire+0x6441/0x7c10\nioc_timer_fn+0x6cec/0x7750\n? blk_iocost_init+0x720/0x720\n? call_timer_fn+0x5d/0x470\ncall_timer_fn+0xfa/0x470\n? blk_iocost_init+0x720/0x720\n__run_timer_base+0x519/0x700\n...\n\nActual impact of this issue was not identified but I propose to fix the\nundefined behaviour.\nThe proposed fix to prevent those out of bound shifts consist of\nprecalculating exponent before using it the shift operations by taking\nmin value from the actual exponent and maximum possible number of bits.","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: fix more out of bound shifts","id":"CVE-2024-49933","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"integer_overflow","year":"2024"},"n_packages":0,"n_references":7,"next":{"headline":"fs/inode: Prevent dump_mapping() accessing invalid dentry.d_name.name","id":"CVE-2024-49934"},"packages":[],"prev":{"headline":"btrfs: don't readahead the relocation inode on RST","id":"CVE-2024-49932"},"products":["Linux"],"published":"2024-10-21","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","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-2024-49933/"}
