Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.10.156

Description A memory allocation issue in the Linux kernel's bnxt en driver has been resolved. The driver needs to track concurrent TPA completions on the aggregation ring, and on P5 chips, the maximum number of concurrent TPA is 256. Memory allocation failure has been reported due to order-5 memory allocation for TPA data. The issue has been fixed by allocating each small chunk of memory separately for each TPA instance, reducing it to order-0 allocations.

Recommendations For Linux kernel version 5.10.156 and earlier, update to a newer version that includes the fix for the memory allocation issue in the bnxt en driver. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
