The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libperf package and not the libperf package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
RDMA/bnxt_re: Free SRQ toggle page after firmware teardown
Free the toggle page only after firmware teardown completes so that an NQ interrupt arriving during bnxt_qplib_destroy_srq() won't write the toggle values to an already-freed page. Move free_page() after bnxt_qplib_destroy_srq().
