The xfer_secondary_pool function in drivers/char/random.c in the Linux kernel 2.4 before 2.4.35 performs reseed operations on only the first few bytes of a buffer, which might make it easier for attackers to predict the output of the random number generator, related to incorrect use of the sizeof operator.

Security readout for executives and security teams

This is an old Linux 2.4 kernel weakness in random number generation. A reseed bug could leave most of an internal buffer insufficiently refreshed, making generated random output easier to predict. The practical risk is mainly to legacy systems that still run or derive security-sensitive keys from affected Linux 2.4 kernels. Exposure is likely limited to obsolete Linux 2.4 deployments, embedded appliances, or vendor-maintained legacy images that did not receive the 2.4.35 or vendor backported fix. Treat this as a legacy-risk cleanup item unless affected systems still generate cryptographic secrets. Prioritize identifying obsolete kernels, confirming vendor fixes, and retiring unsupported assets. Mitigation focus: Upgrade affected Linux 2.4 kernels to 2.4.35 or later where feasible.; For Debian systems, review DSA-1503 and apply the relevant vendor kernel update.; For appliances, request vendor confirmation that the RNG fix was backported..
