{"id":"CVE-2024-50157","summary":"RDMA/bnxt_re: Avoid CPU lockups due fifo occupancy check loop","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/bnxt_re: Avoid CPU lockups due fifo occupancy check loop\n\nDriver waits indefinitely for the fifo occupancy to go below a threshold\nas soon as the pacing interrupt is received. This can cause soft lockup on\none of the processors, if the rate of DB is very high.\n\nAdd a loop count for FPGA and exit the __wait_for_fifo_occupancy_below_th\nif the loop is taking more time. Pacing will be continuing until the\noccupancy is below the threshold. This is ensured by the checks in\nbnxt_re_pacing_timer_exp and further scheduling the work for pacing based\non the fifo occupancy.","modified":"2026-04-02T12:21:18.632909Z","published":"2024-11-07T09:31:34.355Z","related":["SUSE-SU-2024:4314-1","SUSE-SU-2024:4316-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4387-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1","USN-7276-1","USN-7277-1","openSUSE-SU-2024:14500-1","openSUSE-SU-2025:14705-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/50xxx/CVE-2024-50157.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2fb6b2e82413e401b72dfeacd7a60416fcfc5b41"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7998e7efd1d557af118ac96f48ebc569b929b555"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8be3e5b0c96beeefe9d5486b96575d104d3e7d17"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/50xxx/CVE-2024-50157.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-50157"},{"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":"2ad4e6303a6d7518632739eaf67821a3553db1bd"},{"fixed":"7998e7efd1d557af118ac96f48ebc569b929b555"},{"fixed":"2fb6b2e82413e401b72dfeacd7a60416fcfc5b41"},{"fixed":"8be3e5b0c96beeefe9d5486b96575d104d3e7d17"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-50157.json"}}],"schema_version":"1.7.5"}
