Description OSIDB Bzimport 2024-11-07 10:02:37 UTC 
In the Linux kernel, the following vulnerability has been resolved:

RDMA/bnxt_re: Fix out of bound check

Driver exports pacing stats only on GenP5 and P7 adapters. But while
parsing the pacing stats, driver has a check for "rdev->dbr_pacing".  This
caused a trace when KASAN is enabled.

BUG: KASAN: slab-out-of-bounds in bnxt_re_get_hw_stats+0x2b6a/0x2e00 [bnxt_re]
